Nietzsche’s Big History

One of the most succinct formulations of Big History of which I am aware is a brief paragraph from Nietzsche:

“In some remote corner of the universe, poured out and glittering in innumerable solar systems, there once was a star on which clever animals invented knowledge. That was the highest and most mendacious minute of ‘world history’ — yet only a minute. After nature had drawn a few breaths the star grew cold, and the clever animals had to die.

“On Truth and Lie in an Extra-Moral Sense,” Friedrich Nietzsche, Fragment, 1873: from the Nachlass. Translated by Walter Kaufmann

…and in the original German:

In irgend einem abgelegenen Winkel des in zahllosen Sonnensystemen flimmernd ausgegossenen Weltalls gab es einmal ein Gestirn, auf dem kluge Tiere das Erkennen erfanden. Es war die hochmütigste und verlogenste Minute der “Weltgeschichte”: aber doch nur eine Minute. Nach wenigen Atemzügen der Natur erstarrte das Gestirn, und die klugen Tiere mußten sterben.

Über Wahrheit und Lüge im außermoralischen Sinne, Friedrich Nietzsche, 1873, aus dem Nachlaß

This passage has been translated several times, so, for purposes of comparison, here is another translation:

“In some remote corner of the universe that is poured out in countless flickering solar systems, there once was a star on which clever animals invented knowledge. That was the most arrogant and the most untruthful moment in ‘world history’ — yet indeed only a moment. After nature had taken a few breaths, the star froze over and the clever animals had to die.”

ON TRUTH AND LYING IN AN EXTRA-MORAL SENSE (1873), Edited and Translated with a Critical Introduction by Sander L. Gilman, Carole Blair, and David J. Parent, New York and Oxford: OXFORD UNIVERSITY PRESS, 1989

Bertrand Russell, who rarely passed over an opportunity to criticize Nietzsche in the harshest terms, expressed a tragic interpretation of human endeavor that is quite similar to Nietzsche’s capsule big history:

“That Man is the product of causes which had no prevision of the end they were achieving; that his origin, his growth, his hopes and fears, his loves and his beliefs, are but the outcome of accidental collocations of atoms; that no fire, no heroism, no intensity of thought and feeling, can preserve an individual life beyond the grave; that all the labours of the ages, all the devotion, all the inspiration, all the noonday brightness of human genius, are destined to extinction in the vast death of the solar system, and that the whole temple of Man’s achievement must inevitably be buried beneath the debris of a universe in ruins–all these things, if not quite beyond dispute, are yet so nearly certain, that no philosophy which rejects them can hope to stand. Only within the scaffolding of these truths, only on the firm foundation of unyielding despair, can the soul’s habitation henceforth be safely built.”

Bertrand Russell, “A Free Man’s Worship”

Even closer to Nietzsche, in both style and spirit, is the passage that immediately precedes this in the same essay by Russell, told, as with Nietzsche, in the form of a parable:

“For countless ages the hot nebula whirled aimlessly through space. At length it began to take shape, the central mass threw off planets, the planets cooled, boiling seas and burning mountains heaved and tossed, from black masses of cloud hot sheets of rain deluged the barely solid crust. And now the first germ of life grew in the depths of the ocean, and developed rapidly in the fructifying warmth into vast forest trees, huge ferns springing from the damp mould, sea monsters breeding, fighting, devouring, and passing away. And from the monsters, as the play unfolded itself, Man was born, with the power of thought, the knowledge of good and evil, and the cruel thirst for worship. And Man saw that all is passing in this mad, monstrous world, that all is struggling to snatch, at any cost, a few brief moments of life before Death’s inexorable decree. And Man said: `There is a hidden purpose, could we but fathom it, and the purpose is good; for we must reverence something, and in the visible world there is nothing worthy of reverence.’ And Man stood aside from the struggle, resolving that God intended harmony to come out of chaos by human efforts. And when he followed the instincts which God had transmitted to him from his ancestry of beasts of prey, he called it Sin, and asked God to forgive him. But he doubted whether he could be justly forgiven, until he invented a divine Plan by which God’s wrath was to have been appeased. And seeing the present was bad, he made it yet worse, that thereby the future might be better. And he gave God thanks for the strength that enabled him to forgo even the joys that were possible. And God smiled; and when he saw that Man had become perfect in renunciation and worship, he sent another sun through the sky, which crashed into Man’s sun; and all returned again to nebula.

“`Yes,’ he murmured, `it was a good play; I will have it performed again.'”

Here Russell, unlike Nietzsche, gives theological meaning to the spectacle, however heterodox that meaning may be; I can easily imagine someone preferring Russell’s theological version to Nietzsche’s secular version, though both highlight the meaninglessness of human endeavor in a thermodynamic universe.

Our sun — a star among stars — will be a relatively early casualty in the heat death of the universe. While the life of the sun is orders of magnitude beyond the life of the individual human being, as soon as we understood that the sun’s life will pass through predictable stages of stellar evolution, we understood that the sun, like any human being, was born, will shine for a time, and then will die, and, when the sun dies, everything that is dependent upon the light of the sun for life will die also. It is only if we can make ourselves independent of the sun that we will not inevitably share the fate of the sun.

The idea that the sun is a star among stars, and that any star will do in terms of supporting human life, is embodied in a quote attributed to Wernher von Braun by Tom Wolfe and reported in Bob Ward’s book about von Braun:

“The importance of the space program is not surpassing the Soviets in space. The importance is to build a bridge to the stars, so that when the Sun dies, humanity will not die. The Sun is a star that’s burning up, and when it finally burns up, there will be no Earthno Marsno Jupiter.”

quoted in Dr. Space: The Life of Wernher von Braun, Bob Ward, Chapter 22, p. 218, with a footnote giving as the source, “Transcript, NBC’s Today program, New York, November 11, 1998”

Wernher von Braun had seized upon the essential insight of existential risk mitigation, as had many involved in the space program from its inception. As soon as one adopts a naturalistic understand of the place of humanity in the universe, and when technology develops to a point at which its extrapolation offers human beings options and alternatives within the universe, anyone will draw the same conclusion. Another quote from von Braun makes the same point in another way:

“…man’s newly acquired capability to travel through outer space provides us with a way out of our evolutionary dead alley.”

Bob Ward, Dr. Space: The Life of Wernher von Braun, Annapolis, US: Naval Institute Press, 2013.

I have previously written about the idea that humanity is a solar species, but the fact that humanity and the biosphere from which we derive has been utterly dependent upon solar insolation has been an accident of history. Any sun will do. We can, accordingly, re-conceive humanity as a stellar species, the kind of species that requires a star and its planetary system to make a home for ourselves. In this sense, all species of planetary endemism are stellar species.

Even this idea of immigration to another star, and of any other star being as good as the sun, is ultimately too narrow. Our sun, or any star, can be the source of energy that powers our civilization, but it can easily be seen that substitute forms of energy could equally well power the future of our civilization, and that it has merely been an historical contingency — a matter of our planetary endemism — that we have been dependent upon a single star, or upon any star, for our energy needs.

This more radical and farther-reaching vision is embodied in a quote attributed to Ray Bradbury by Oriana Fallaci:

“Don’t let us forget this: that the Earth can die, explode, the Sun can go out, will go out. And if the Sun dies, if the Earth dies, if our race dies, then so will everything die that we have done up to that moment. Homer will die. Michelangelo will die, Galileo, Leonardo, Shakespeare, Einstein will die, all those will die who now are not dead because we are alive, we are thinking of them, we are carrying them within us. And then every single thing, every memory, will hurtle down into the void with us. So let us save them, let us save ourselves. Let us prepare ourselves to escape, to continue life and rebuild our cities on other planets: we shall not be long of this Earth! And if we really fear the darkness, if we really fight against it, then, for the good of all, let us take our rockets, let us get well used to the great cold and heat, the no water, the no oxygen, let us become Martians on Mars, Venusians on Venus, and when Mars and Venus die, let us go to the other solar systems, to Alpha Centauri, to wherever we manage to go, and let us forget the Earth. Let us forget our solar system and our body, the form it used to have, let us become no matter what, lichens, insects, balls of fire, no matter what, all that matters is that somehow life should continue, and the knowledge of what we were and what we did and learned: the knowledge of Homer and Michelangelo, of Galileo, Leonardo, Shakespeare, of Einstein! And the gift of life will continue.”

Oriana Fallaci, If the Sun Dies, New York: Atheneum, 1966, pp. 14-15

Fallaci refers to this as a “prayer,” and indeed we might see this as a prayer or a catechism of the Space Age — not a belief, not merely belief, but an imperative ever-present in the hearts and minds of those who have fully imbibed the spirit of the age and who seek to carry that spirit forward with evangelical fervor, proselytizing to the masses and bringing them to the True Faith through purity of will and vision — another way of saying naïveté.

Do the clever animals have to die? No, not yet. Not if they are clever enough to move on to another planet, another star, another galaxy. Not if they are clever enough to change themselves so that, when the changed conditions of the universe in which they exist no longer allow the lives of clever animals to continue, what the clever animals have achieved can be preserved in some other way, and they themselves can be preserved in another form.

A Conceptual Overview

What is the relationship between planetary endemism and the overview effect? This is the sort of question that might be given a definitive formulation, once once we have gotten sufficiently clear in our understanding of these ideas and their ramifications. I’m not yet at the point of formulating a definitive expression of this relationship, but I’m getting closer to it, so this post will be about formulating relationships among these and related concepts in a way that is hopefully clear and illuminating, while avoiding the ambiguities inherent in novel concepts.

This post is itself a kind of overview, attempting to show in brief compass how a number of interrelated concepts neatly dovetail and provide us with a rough outline of a conceptual overview for understanding the origins, development, distribution, and destiny of civilization (or some other form of emergent complexity) in the universe.

stars-0

The Stelliferous Era

The Stelliferous Era is that period of cosmological history after the formation of the first stars and before the last stars burn out and leave a cold and dark universe. In the cosmological periodization formulated by Fred Adams and Greg Laughlin, the Stelliferous Era is preceded by the Primordial Era and followed by the Degenerate Era. During the Primordial Era stars have not yet formed, but matter condenses out of the primordial soup; during the Degenerate Era, the degenerate remains of stars, black holes, and some exotic cosmological objects are to the found, but the era of brightly burning stars is over.

What typifies the Stelliferous Era is its many stars, radiating light and heat, and whose nucleosynthesis and supernova explosions forge heavier forms of matter, and therefore the chemical and minerological complexity from which later generations of (high metallicity) stars and planets will form. (A Brief History of the Stelliferous Era is an older post about the Stelliferous Era that needs to be revised and updated.)

In comparison to the later Degenerate Era, Black Hole Era, and Dark Era of cosmological history, the Stelliferous Era is rather brief, extending from 106 to 1014 years from the origins of the universe, and almost everything that concerns us can be further reduced to the eleventh cosmological decade (from 10 billion to 100 billion years since the origin of the universe). Since this cosmological periodization is logarithmic, the later periods are even longer in duration than they initially appear to be.

Our interest in the Stelliferous Era, and, more narrowly, our interest in the eleventh decade of the Stelliferous Era, does not rule out interesting cosmological events in other eras of cosmological history, and it is possible that civilizations and other forms of emergent complexity that appear during the Stelliferous Era may be able to make the transition to survive into the Degenerate Era (cf. Addendum on Degenerate Era Civilization), but this brief period of starlight in cosmological history is the Stelliferous Era window in which it is possible for peer planetary systems, peer species, and peer civilization to exist.

planetary surfaces

Planetary Endemism

Planetary Endemism is the condition of life during the Stelliferous Era as being unique to planetary surfaces and their biospheres. Given the parameters of the Stelliferous Era — a universe with planets, stars, and galaxies, in which both water (cf. The Solar System and Beyond is Awash in Water) and carbon-based organic molecules (cf. Mixed aromatic–aliphatic organic nanoparticles as carriers of unidentified infrared emission features by Sun Kwok and Yong Zhang) are common — planetary surfaces are a “sweet spot” for emergent complexities, as it is on planetary surfaces that energy from stellar insolation can drive chemical processes on mineral- and chemical-rich surfaces. The chemical and geological complexity of the interface between atmosphere, ocean, and land surfaces provide an opportunity for further emergent complexities to arise, and so it is on planetary surfaces that life has its best opportunity during the Stelliferous Era.

Planetary endemism does not rule out exotic forms of life not derived from water and organic macro-molecules, nor does it rule out life arising in locations other than planetary surfaces, but the nature of the Stelliferous Era and the conditions of the universe we observe points to planetary surfaces being the most common locations for life during the Stelliferous Era. Also, the “planetary” in “planetary endemism” should not be construed too narrowly: moons, planetesimals, asteroids, comets and other bodies within a planetary system are also chemically complex loci where stellar insolation can drive further chemical processes, with the possibility of emergent complexities arising in these contexts as well.

The Homeworld Effect

The homeworld effect is the perspective of intelligent agents still subject to planetary endemism. When the emergent complexities fostered by planetary endemism rise to the level of biological complexity necessary to the emergence of consciousness, there are then biological beings with a point of view, i.e., there is something that it is like to be such a biological being (to draw on Nagel’s formulation from “What is it like to be a bat?”). The first being on Earth to open its eyes and look out onto the world possessed the physical and optical perspective dictated by planetary endemism. As biological beings develop in complexity, adding cognitive faculties, and eventually giving rise to further emergent complexities, such as art, technology, and civilization, embedded in these activities and institutions is a perspective rooted in the homeworld effect.

The emergent complexities arising from the action of intelligent agents are, like the biological beings who create them, derived from the biosphere in which the intelligent agent acts. Thus civilization begins as a biocentric institution, embodying the biophilia that is the cognitive expression of biocentrism, which is, in turn, an expression of planetary endemism and the nature of the intelligent agents of planetary endemism being biological beings among other biological beings.

The homeworld effect does not rule out the possibility of exotic forms of life or unusual physical dispositions for life that would not evolve with the homeworld effect as a selection pressure, but given that planetary endemism is the most likely existential condition of biological beings during the Stelliferous Era, it is to be expected that the greater part of biological beings during the Stelliferous Era are products of planetary endemism and so will be subject to the homeworld effect.

surface-earth-space

The Overview Effect

The overview effect is a consequence of transcending planetary endemism. As biocentric civilizations increase in complexity and sophistication, deriving ever more energy from their homeworld biosphere, biocentric institutions and practices begin to be incrementally replaced by technocentric institutions and practices and civilization starts to approximate a technocentric institution. The turning point in this development is the industrial revolution.

Within two hundred years of the industrial revolution, human beings had set foot on a neighboring body of our planetary system. If a civilization experiences an industrial revolution, it will do so on the basis of already advancing scientific knowledge, and within an historically short period of time that civilization will experience the overview effect. But the unfolding of the overview effect is likely to be a long-term historical process, like the scientific revolution. Transcending planetary endemism means transcending the homeworld effect, but as the homeworld effect has shaped the biology and evolutionary psychology of biological beings subject to planetary endemism, the homeworld effect cannot be transcended as easily as the homeworld itself can be transcended.

For biological beings of planetary endemism, the overview effect occurs only once, though its impact may be gradual and spread out over an extended period of time. An intelligent agent that has evolved on the surface of its homeworld leaves that homeworld only once; every subsequent world studied, explored, or appropriated (or expropriated) by such beings will be first encountered from afar, over astronomical distances, and known to be a planet among planets. A homeworld is transcended only once, and is not initially experienced as a planet among planets, but rather as the ground of all being.

The uniqueness of the overview effect to the homeworld of biological beings of planetary endemism does not rule out further overview effects that could be experienced by a spacefaring civilization, as it eventually is able to see its planetary system, its home galaxy, and its supercluster as isolated wholes. However, following the same line of argument above — stars and their planetary systems being common during the Stelliferous Era, emergent complexities appearing on planetary surfaces characterizing planetary endemism, organisms and minds evolving under the selection pressure of the homeworld effect embodying geocentrism in their sinews and their ideas — it is to be expected that the overview effect of an intelligent agent first understanding, and then actually seeing, its homeworld as a planet among other planets, is the decisive intellectual turning point.

Bifurcation of Planetary and Spacefaring Civilizations

What I have tried to explain here is the tightly-coupled nature of these concepts, each of which implicates the others. Indeed, the four concepts outlined above — the Stelliferous Era, planetary endemism, the homeworld effect, and the overview effect — could be used as the basis of a periodization that should, within certain limits, characterize the emergence of intelligence and civilization in any universe such as ours. Peer civlizations would emerge during the Stelliferous Era subject to planetary endemism, and passing from the homeworld effect to the overview effect.

If such a civilization continues to develop, fully conscious of the overview effect, it would develop as a spacefaring civilization evolving under the (intellectual) selection pressure of the overview effect, and such a civilization would birfurcate significantly from civilizations of planetary endemism still exclusively planetary and still subject to the homeworld effect. These two circumstances represent radically different selection pressures, so that we would expect spacefaring civilizations to rapidly speciate and adaptively radiate once exposed to these novel selection pressures. I have previously called this speciation and adaptive radiation the great voluntaristic divergence.

2017-jan-1

Early in the history of this blog I wrote about a snowstorm in Portland during December 2008, Snow in Portland, More Snow, and Lessons from a Snowstorm, and now Portland has had another uncharacteristically heavy snowfall eight years on. I am always fascinated to watch the rapidly changing behaviors of the population of a city as it responds to rapidly changing conditions, and I can’t help but extrapolate from these observations to other disruptions to the ordinary business of life.

2017-jan-2

The initial impact of a big snowstorm (in a temperate climate where snowstorms are infrequent) is chaos and frantic activity. After the initial chaos, the city goes quiet, and driving around a city after it has gone quiet gives an apocalyptic feeling, as though the end of the world has come. A snowstorm is, in miniature, the collapse of a complex society, such as Joseph Tainter wrote about:

“Collapse, as viewed in the present work, is a political process. It may, and often does, have consequences in such areas as economics, art, and literature, but it is fundamentally a matter of the sociopolitical sphere. A society has collapsed when it displays a rapid, significant loss of an established level of sociopolitical complexity. The term ‘established level’ is important. To qualify as an instance of collapse a society must have been at, or developing toward, a level of complexity for more than one or two generations. The demise of the Carolingian Empire, thus, is not a case of collapse — merely an unsuccessful attempt at empire building. The collapse, in turn, must be rapid — taking no more than a few decades — and must entail a substantial loss of sociopolitical structure. Losses that are less severe, or take longer to occur, are to be considered cases of weakness and decline.”

Joseph A. Tainter, The Collapse of Complex Societies, Cambridge: Cambridge University Press, 1988, p. 4

Of course, the collapse precipitated by a snowstorm is not a political collapse, but it is a rapid and significant loss of an established level of complexity, and a temporary return to a simpler way of life.

2017-jan-3

When someone abandons their car and walks away, eventually walking around their neighborhood rather than driving, this is a significant simplification of life, and the simplest level to which life can be reduced is that of mere survival, or perhaps I should say subsistence. Because the conditions of a snowstorm or a flood or some similar disruption (say, a power outage) are temporary it does not force a return to subsistence agriculture, but there are occasions when one finds oneself no longer concerned by the technical details of one’s work, and one is only fighting to stay alive, as all other considerations are thrust aside in order to deal with the immediacy of the circumstances. However, it is easy to imagine (especially with the looming specter of climate change) that a storm could be the first disruption in a series of escalating disruptions that could force society to abandon its complex institutions and way of life, returning to subsistence agriculture, or even nomadic hunting and gathering. If a large flood failed to recede after a few days because water levels had crept higher, the disruption of the the storm that caused the flood would be a mere foretaste of things to come.

2017-jan-4

There is a great deal of social momentum behind the ordinary business of life, and one can observe that people continue to go about their routines in the routine way for as along as possible — right up the moment when it becomes actually physically impossible to continue to going about things as usual. Thus one sees people setting out for work as usual even as the snow is beginning to fall, and as the snow piles up they try to continue to go about their business. It is only when, on the drive home, their car will not move forward another inch, when they abandon it and walk away. As long as a choice remains, most will choose to continue with the ordinary business of life; the routine is only abandoned when no choice remains and one is forced by circumstances to alter one’s behavior.

2017-jan-5

There is also a strong desire to return to normalcy after the disruption of a storm, so that at the first sign of conditions improving, people head out again in large numbers. In the case of the snowstorms I have seen in my years, this creates a problem because the main roads will be cleared of snow, but the secondary roads and parking lots are still icy, and many people over-confidently driving at full speed on the highways cause problems for themselves and others. The desire for the return to normalcy is a desire for the familiar normalcy, the old normal, while the conditions of the storm, strange and unfamiliar at first, dictate a new normal, and there is a tension between the old normal and the new normal as society attempt to adjust and compensate for changed conditions. As long as the conditions of the new normal are temporary, the old normal will return, but the longer the conditions persist, the longer the new normal persists, and, as the phrase implies, the new normal eventually becomes familiar if it endures for a sufficient period of time.

2017-jan-6

I imagine that in the case of the true collapse of societies, and not merely an ephemeral collapse precipitated by a weather event, that this desire to return to normalcy results in a lot of false starts, like commuters returning to the roads too soon after a snowstorm. There are probably many hopeful moments in the collapse of a society when people come out of their hiding places and venture out into the world again, hoping that they can return to their routines. When Sarajevo was under siege during the Balkan wars of the 90s, it was several years before life could return to normal. Similarly, when the First and Second World Wars began, it would be several years before normalcy would return.

2017-jan-7

When a society well and truly collapses, never to rise again, one can imagine for years or for decades people looked for a return to normalcy that would never come. Or if life seemed to return to normal for a time — for weeks or months or years — it was only a deceptive return to old ways that would soon disappear forever. When Roman cities in the west began to fail, there was probably a movement like the ebb and flow of the tide, when people would abandon their city, then go back, then abandon it again. Each time those who returned would be fewer in number, there would be fewer shops open, and fewer goods for sale, and there might be increasing lengths of time between abandonment and return, until eventually the period of abandonment stretched into years, and the city fell into disrepair, fit only for looting from the ruins.

Indiana Jones is adventure science at its most exciting, though the films are more often about looting and destroying sites rather than preserving them.

Indiana Jones is adventure science at its most exciting, though the films are more often about looting and destroying sites rather than preserving them.

In my recent paper “A Manifesto for the Scientific Study of Civilization” I argued that the study of civilization should be scientific, and that a scientific theory of civilization would be a formal theory. Prior to this, I argued in Rational Reconstructions of Time that a formal historiography is possible. What is the connection between these two claims? In A Metaphysical Disconnect I suggested that it is a philosophical problem that philosophies of time have not been tightly-coupled with philosophies of history. This implies that a formal theory of time could be tightly-coupled with a formal theory of history, and a formal theory of history would presumably encompass (or, at least, overlap) a theory of civilization. A formal theory of civilization, then, might ultimately follow from formal historiography.

I fully understand that these are strange claims for me to be making. What in the world do I mean by a formal theory of time, of history, or of civilization? How could a science of civilization be a formal science? What is a formal science, anyway? Despite the burgeoning growth of computer science in our time, which is the latest addition to the formal sciences, the very idea of the formal as a distinct category of thought (distinct, especially, from the material) seems odd and alien to us, and the distinction between the formal sciences and the natural sciences seems archaic. What are the formal sciences? Here is one view:

“To put it in Kantian terms, the formal sciences dealt with the Reine Anschauung as opposed to empirical data. By that they have been connected to the methodology of mathematics and logic, thereby being part of both the philosophical tradition and the newly won applications of mathematical sciences to the natural sciences and engineering. Both the object and the methods of the Formal sciences were recognized as different from the Natural and the Social sciences.”

“The Formal Sciences: Their Scope, Their Foundations, and Their Unity” by Benedikt Löwe, Synthese, Vol. 133, No. 1/2, Foundations of the Formal Sciences I (Oct.-Nov., 2002),pp. 5-11

In the same paper there is an explicit attempt to answer the question, “What are the Formal Sciences?” Two answers are given:

● Answer 1: “There is a profound duality in the classification of sciences according to their scientific approaches: some sciences are empirical, some are formal. The former deal with predictions and their falsification, the latter with the understanding of systems without empirical component, be it man-made systems (literary systems, the arts or social systems) or formal systems”.

● Answer 2: “Formal sciences are those that deal with the deductive analysis of formal systems (i.e., systems independent of direct human influence)”.

At present I am not going to analyze these differing definitions of the formal sciences, but I will leave them to percolate in the back of the mind of the reader in order to return to the question at hand: the study of civilization as a formal science, i.e., one formal science among many other formal sciences, however we choose to define them.

We can get a hint of what a formal science of civilization would look like from structuralist historians and historians of the Annales school, the chief representatives of the latter being Marc Bloch, Lucien Febvre, and Fernand Braudel. Marc Bloch’s two volume history of feudalism, in particular, stands out as a great achievement in the genre, with chapters devoted to features of feudal society rather than to great events and historical turning points. Whereas John Florio had Montaigne say that I describe not the essence but the passage, Bloch sought to describe not the passage, but the essence. (I previously quoted from Bloch in Hegel and the Overview Effect.)

There is (or, there will be) no one, single way to approach formal historiography, in the same way that there is no one, single axiomatization of set theory. Even if one agrees with Gödel that set theory describes a “well-determined reality” (a realist conception that most people today would agree describes the past, even if they would hesitate to say the same of set theory), there are, as yet, many distinct approaches to that reality. So too with formal historiography; there will be many distinct formalisms for the organization, exhibition, and exposition of the well-determined reality of history.

I reveal myself as being more of a traditionalist than Bloch by my preference for approaching a theory of civilization by way of a theory of history, and a theory of history by way of a theory of time. This is “traditional” in the sense that, as I have remarked many times in other places, it has been traditional to study civilization by studying history, rather than studying civilization as an object of knowledge in its own right. I retain the historical perspective, and indeed even many of the prejudices of historians (these come naturally to me), but I can also see beyond history sensu stricto and to a science of time, a science of history, and a science of civilization that lies beyond history even as it draws from the tradition all that that tradition has to offer.

Both the essentialist approach of Bloch and the Annales school, and my own quasi-historical approach to a formal science of civilization, may each have something to contribute to a theory of civilization. Obviously, these are not the only ways to study civilization. Civilization also can be studied as an empirical science — this is probably how most would conceive a science of civilization — and even as an adventure science. What is adventure science?

Together with Dr. Jacob Shively, I wrote an article about adventure science, Adventure Science Enters the Space Age, noting that “big science” has become the paradigm of scientific activity at the present time, but when individual human beings are able to go exploring they will be able to pluck the low-hanging fruit of exploration and discovery. Adventure science characterizes the earliest stage of a science when discoveries can be made simply by traveling to an exotic locale and being the first to describe some phenomenon never before documented by science. Such discoveries are difficult for us now, because the low-hanging fruit of terrestrial discovery has all been plucked, but once off Earth, new worlds will beckon with new discoveries waiting to be made. This will be a new Golden Age of adventure science.

Paradoxically, the science of civilization will become an adventure science (if it ever becomes one) quite late in its history, so that adventure science will characterize a science of civilization not in its earliest stages, but in its latest stages. But civilization has had a kind of early adventure science phase as well. Archaeology was once the paradigm of adventure science — as attested to by the cinematic adventures of Indiana Jones and the television adventures of Relic Hunter — when real life explorers entered jungles and deserts and swamps to search for long lost cities. Archaeology is perhaps the closest existing discipline that we have to a true science of civilization — archaeologists have many theories of civilization — so that the adventure science that archaeology once was, was at the same time (at least in part) an adventure science of civilization. And it may be so again, when xenoarchaeologists lead the way, looking for the ruins of alien civilizations.

All of the resources of contemporary big science, with its thousands of researchers and multi-generational socially-organized research programs, will be necessary in order to develop the science that will make possible the production of interstellar vessels. In my Centauri Dreams post, The Interstellar Imperative, I wrote, “A starship would be the ultimate scientific instrument produced by technological civilization, constituting both a demanding engineering challenge to build and offering the possibility of greatly expanding the scope of scientific knowledge by studying up close the stars and worlds of our universe, as well as any life and civilization these worlds may comprise.” Once starships become a reality, they will make possible the empirical study of civilizations, which will begin as an adventure science, the primary qualification for which will be a willingness to tolerate discomfort and to travel to distant places with a determination to document every new sight that one sees.

Geology will become an adventure science like this once again as soon as human beings have the freedom to travel around our solar system; biology and ecology will become adventure sciences once again as soon as we can visit other living worlds. The study of civilization will not become an adventure science until human beings are free to travel about the cosmos, so that this is a very distant prospect, but still a hopeful one. If we do not find a number of interesting civilizations to study, we will build a number of interesting civilizations, and eventually these will be studied in their turn. In this latter instance, the science of civilization will only become an adventure science after civilization has expanded throughout the cosmos, has forgotten the saga of its expansion, and then rediscovers itself across a plurality of worlds. And once again we will be forced to reckon with Hegel’s prescience for having said that the owl of Minerva takes flight only with the setting of the sun.

'Anywhen' by Chris Foss perfectly expresses the mystery and adventure of exploration. Perhaps some day in the far future, the study of civilization will be an adventure science in which such exploration takes a central role.

Four Species of Big History

In Rational Reconstructions of Time I characterized Big History as the culmination, the natural teleology, as it were, of scientific historiography.

While in several posts I have attempted to analyze the positivistic outlook of much contemporary science, which views philosophy like a vampire views garlic and holy water, we all know that the absence of an explicit and acknowledged metaphysic virtually guarantees an implicit and hidden metaphysic. There is a considerable philosophical literature on the metaphysical presuppositions of science; I have written about this also, and in Reduction, Emergence, Supervenience I distinguished between four phases of scientific metaphysics: the eliminativist, the reductionist, the emergentist, and the supervenientist (although when I wrote that post I hadn’t yet fully distinguished eliminativism as a scientific metaphysic).

In so far as Big History constitutes the culmination of scientific historiography, Big History is history informed by the metaphysical presuppositions of natural science. If, then, we take my four divisions of scientific metaphysics as the possible forms that these metaphysical presuppositions can take, we have the four metaphysical forms that Big History can take: eliminativist big history, reductionist big history, emergentist big history, and supervenientist big history. I will consider each of these possibilities in turn.

Already in Reduction, Emergence, Supervenience, in a section titled “Reduction, emergence, and supervenience as philosophies of history,” I began an explicit outline of scientific historiography as founded on these scientific metaphysics:

● Eliminativist Historiography Human history is illusory and should be eliminated as a category of thought; everything history states that is true can be better and exhaustively expressed in a scientific language that makes no use of folk historiography. Therefore we can substitute scientific explanations for historical explanation without change in truth or loss of truth. It would be sufficient to provide a total description of the physics of the past without any overlay of human meanings or values.

● Reductionist Historiography Human history is nothing but natural history, or the history of the world as related by science (which is not necessarily the same thing as natural history). If human meanings and values seem to play a constitutive role in history (or even human consciousness, in the form of making conscious choices), this is merely illusory, an error the follows from human limitations.

● Emergentist Historiography Human history is a whole that emerges from natural history that possesses unique properties as a whole that are not attributable to natural historical processes.

● Supervenient Historiography Human history supervenes on natural history, or the history of the world as related by science. In other words, there can be no change in human history without there being a subvening change in natural history. The A-properties of history supervene upon the B-properties of scientifically delineated history.

The above is a modified version of what I wrote in my earlier post.

eliminativism

Eliminativist Big History

What would be eliminated in a eliminativist big history? Presumably the concepts and categories of folk historiography, as those positivist enthusiasts of eliminativism generally focused on eliminating “folk” concepts (cf. Folk Concepts and Scientific Progress). What are the folk concepts of historiography? Folk concepts of historiography would probably include all or most of the factors highlighted by personalism in history, i.e., concepts of individual human agency, which also might be identified with folk psychology: motivation, intention, purpose, meaning, value, and so on. A scientific historiography would also presumably seek to eliminate all the folk concepts still present in the special sciences made use of by scientific historiography.

How would this play out in Big History? Big History pursued as a form of metaphysical reductionism would resemble a spare and stripped-down scientific historiography more than any other metaphysical formulation under consideration here. The only novel element would be treating the whole history of the universe in these terms of scientific historiography, instead of restricting the scope of such a scientific historiographical enterprise.

Indeed, Otto Neurath, one of the movers and shakers of the Vienna Circle, already foresaw such a reductionist Big History, which he called “Cosmic History”:

“…we may look at all sciences as dovetailed to such a degree that we may regard them as parts of one science which deals with stars, Milky Ways, earth, plants, animals, human beings, forests, natural regions, tribes, and nations — in short, a comprehensive cosmic history would be the result of such an agglomeration… Cosmic history would, as far as we are using a Universal Jargon throughout all branches of research, contain the same statements as our unified science. The language of our Encyclopedia may, therefore, be regarded as a typical language of history. There is no conflict between physicalism and this program of cosmic history.”

Otto Neurath, Foundations of the Social Sciences, Chicago and London: The University of Chicago Press, 1970 (originally published 1944), p. 9

For Neurath to assert that, “There is no conflict between physicalism and this program of cosmic history,” is to say that history can be subsumed under the physicalism of the Encyclopedia of Unified Science in which the above-quoted monograph appeared, and this means that history could be reduced to protocol sentences of physics. While most historians would, I think, not find this to be congenial, it is remarkable that Neurath conceived this cosmic history as part of the program of unified science, and that it resembles so closely the ambition of Big History.

reductionism

Reductionist Big History

Reductionism usually takes the form of reducing some higher-level, more comprehensive (or more complex) state-of-affairs to a lower-level, less comprehensive (or less complex) state of affairs; without denying the reality of the higher-level state-of-affairs, but also denying the latter metaphysical primacy. A good example of this is Hilbert’s philosophy of mathematics, which sought to preserve Cantor’s set theory and transfinite numbers, but only by making a distinction between real and ideal mathematics, consigning Cantor to the latter and reserving the former for quasi-constructivist, proto-finitist mathematics. Hilbert “reduced” ideal mathematics to real mathematics, but without insisting upon the elimination of ideal mathematics, and in a similar way reductionist historiography would “reduce” human history to natural history (or to time itself), without insisting upon the elimination of human history.

Like the idealist doctrine of degrees of being, in reductionism there are degrees of reality. Without denying the reality of higher-level, more comprehensive states-of-affairs, these are said to be reducible to, or, “nothing but” the lower-level, less comprehensive states-of-affairs. If we understand history to be a higher-level, more comprehensive conception than time, the reductionist big history would take the form of asserting that history is reducible to time, or that history is nothing but time. But the reductionist does not take the additional step taken by the eliminativist, so that the reductionist does not assert either that history is unreal or time unreal, or that these are meaningless. Both are real, but each enjoys a different degree of reality. This interpretation of reductionism as a doctrine of degrees of reality could be given further exposition, but it opens up so many problems (and so many opportunities) that I will not consider it further at present.

It must be admitted that there are strong reductionist strains in scientific historiography, and many of these are retained in the movement of the ideas of scientific historiography into Big History. If it is argued that some major historical development is entirely due to climate change, or geography, or cosmological circumstances like the fact that Earth had only one moon, and so on, we are here approximating a purely reductionist Big History. This kind of reductionism is antithetical to personalism in history, in which human actors loom large, but while the eliminativist Big Historian might simply do without any reference to human actors in history, the reductivist Big Historian would retain human actors, but would ascribe their actions to larger forces, be those forces fundamental physics, cosmology, geography, or something else.

emergentism

Emergentist Big History

Emergentism, unlike eliminationism and reductionism, has a prominent and explicit place in Big History. Big Historians usually recognize eight thresholds of emergent complexity in the history of the universe — the big bang, stars, chemical elements, planets, life, human beings, argiculture, and modernity — at least, these are the thresholds made canonical by David Christian. There are alternative periodizations based on thresholds of emergent complexity, but most Big Historians recognize some sort of periodization of the history of the universe entire based on emergent complexity.

One of the similes employed by contemporary philosophers to explain the ambition of metaphysics is the idea of carving nature at the joints. This is precisely what Big Historians are trying to do in using emergent complexity as a basis for periodization. Historians have always employed periodizations; with Big History, these periodizations are now drawn not from human conventions, but from the actual history of nature itself, from the very structure of the universe, and thus are quantifiable and can be studied by science. Here scientific historiography is “cashed out” by making periodization subject to rigorous scientific research. It would be difficult to imagine a more perfect exemplification of a metaphysical synthesis of science and history.

While emergentism features prominently in Big History, the Big History version of emergent complexity has not yet been a focus of research by philosophers, and so it lacks the clarity and ambition to system that we would expect to find in a more philosophical account. In some accounts of Big History, emergentism is invoked rather than explained or exhibited, so there remains much work to be done. Big History employs emergentism, but it could not be said that Big History is as yet a thoroughly emergentist conception of history — we could apply the idea of emergence more systematically and exhaustively — nor could we say that the possibilities of emergentism in the philosophy of history have been even sketched out. I suspect that we will begin to see this in the coming decade.

supervenience

Supervenientist Big History

I know of no explicit formulation of supervenientist Big History, but as a more subtle and sophisticated philosophical doctrine than its predecessors eliminationism, reductionism, and emergentism, it is not difficult to imagine that someone will, sooner rather than later, employ the metaphysical tools of supervenience to the analysis of history. Supervenience could be interpreted in a way consistent with reductionism or emergentism, so these iterations of the metaphysics of Big History could be considered precursors that eventually lead to a more sophisticated formulation in terms of supervenience. (It should, however, be pointed out that the formulation of emergentism in the first section above, “Human history is a whole that emerges from natural history that possesses unique properties as a whole that are not attributable to natural historical processes,” is not consistent with supervenience, while implies that there could be formulations of emergentist historiography inconsistent with supervenientist historiography.)

Because supervenience is a sophisticated metaphysical doctrine, there are many different formulations with subtle differences. Thus there could be many different forms of supervenientist Big History (as noted above, some compatible with emergence, and some not, and the same could be said of elimination and reduction), depending upon the variety of supervenience one employs in demonstrating that historical properties supervene on some base properties. But what do we take to be the base properties upon which historical properties supervene? Are these base properties temporal properties, or human properties, or physical properties of the universe? One of the reasons I have been emphasizing the relationship between time and history is because in my recent post A Metaphysical Disconnect I argued that the fact that the philosophy of time is not tightly-coupled with the philosophy of history points to a major disconnect. Seen in the might of supervenience, that might have historical properties supervene on properties of human societies rather than properties of time, there is here the suggestion of an argument in favor of the disconnect that I noted.

A supervenientist Big History rapidly becomes so bogged down in technical details that I will have to save an attempt at a brief exposition for a later time, as I do not yet have a grasp of this that would allow me to summarize the issues with any degree of accuracy. Nevertheless, I will not the possibility of a supervenientist Big History as a direction that research into the metaphysics of Big History could take in the near future.

The Future: Big History after Scientific Metaphysics

In the fullness of time, assuming our civilization does not falter and so continues in its development (i.e., assuming the failure condition), the contemporary paradigm of science will become so altered by revision and addition that it will no longer be recognizable as what we today think of as science. Science itself will be forced to expand and to change in order to encompass objects of knowledge not accessible by contemporary scientific methods (e.g., consciousness). This change will be both influenced by changes in our philosophical outlook, and will in turn influence the shaping of our philosophical outlook. As a consequence, the metaphysical presuppositions of science will evolve along with the evolution of scientific method. The quadripartite schema I have laid out above of eliminativist, reductionist, emergentist, and supervenientist scientific metaphysics will give way to other ways of conceptualizing the world.

Big History, as an expression of scientific historiography, and thus an expression of science and of scientific civilization, will change along with the changes in scientific method and metaphysical presuppositions of history. There will always be a division of history that takes as its remit the most comprehensive conception of history, and in this sense there will always be Big History, though eventually it will be Big History without the metaphysical presuppositions of science that now subtly inform scientific historiography.

Scientific metaphysics is the intellectual superstructure of scientific civilization. In the illustration below I suggest an overall tripartite distinction among pre-scientific metaphysics, scientific metaphysics (i.e., the metaphysics that facilitates science), and post-scientific metaphysics. There is almost certain further developments of scientific metaphysics to come, which will continue to illuminate the scientific civilization of which we are part. But at some point the accumulated differences will push us over a threshold beyond which the scientific paradigm no longer applies, and that post-scientific civilization will have to be illuminated by a post-scientific metaphysics.

Janus, the Roman god of beginnings and portals, had two faces, one looking into the past and another looking into the future.

Janus, the Roman god of beginnings and portals, had two faces, one looking into the past and another looking into the future.

In my recent Manifesto for the Study of Civilization I employed the phrase history in an extended sense. Here is a bit more context:

“One form that the transcendence of an exclusively historical study of civilization can take is that of extrapolating historical modes of thought so that these modes of thought apply to the future as well as to the past (and this could be called history in an extended sense).”

In several posts I have developed what I call concepts in an extended sense, as in Geocentrism in an Extended Sense and “biocentrism in an extended sense” in Addendum on the Technocentric Thesis and “ecology in an extended sense” in Intelligent Invasive Species.

In Developmental Temporality I wrote:

“With the advent of civilization in the most extended sense of that term, comprising organized settled agricultural societies and their urban centers, planning for the future becomes systematic.”

And in Reduction, Emergence, Supervenience I wrote:

“Philosophy today, then, is centered on the extended conceptions of ‘experience’ and ‘observation’ that science has opened up to us, and these extended senses of experience and observation go considerably beyond ordinary experience, and the prima facie intellectual intuitions available to beings like ourselves, whose minds evolved in a context in which perceptions mattered enormously while the constituents and overall structure of the cosmos mattered not at all.”

In these attempts to extrapolate, expand, and extend concepts beyond their ordinary usage — the result of which might also be called overview concepts — each traditional concept must be treated individually, as there is a limit that is demarcated by the intrinsic meaning of the concept, and these limits are different in each case. With history, the extrapolation of the concept is obvious: history has taken the past as its remit, but history in an extended sense would apply to the totality of time. This is already being done in Big History.

When I attended the second IBHA conference in 2014 I was witness to a memorable exchange that I described in 2014 IBHA Conference Day 2:

“During the question and answer session, a fellow who had spoken up in previous sessions with questions stood up and said that there were (at least) two conceptual confusions pervasive throughout discussions at this conference: 1) that something could come from nothing (presumably a reference to how the big bang is framed, though this could have been intended more generally as a critique of emergentism) and, 2) that history can say anything about the future. The same individual (whose name I did not get) said that no one had given an adequate definition of history, and then noted that the original Greek term for history meant ‘inquiry.’ Given this Grecian (or even, if you like, Herodotean) origin for the idea of history as an inquiry, I immediately asked myself, ‘If one can conduct an inquiry into the past, why cannot one also conduct an inquiry into the future?’ No doubt these inquires will be distinct because one concerns the past and the other the future, but cannot they be taken up in the same spirit?”

There was a note of frustration in the voice of the speaker who objected to any account of the future as a part of history, and while I could appreciate the source of that frustration, it reminded me of every traditionalist protest against the growth of scientific knowledge made possible by novel methods not sanctioned by tradition. In this connection I think of Isaiah Berlin’s critique of scientific historiography, which I previously discussed in Big History and Scientific Historiography.

Berlin argued that the historical method is intrinsically distinct from the scientific method, so that there can be no such thing as scientific historiography, i.e., that the intrinsic limitations of the concept of history restricts history from being scientific in the way that the natural sciences are scientific. While Berlin’s objection to scientific historiography is not stated in terms of restricting the expansion of historical modes of thought, his appeal to a nature of history intrinsically irreconcilable with science and the scientific method is parallel to an appeal to the nature of history as being intrinsically about the past (thus intrinsically not about the future), hence there can be no such thing as a history that includes within it the study of the future in addition to the study of the past.

Here is a passage in which Berlin characterizes distinctively historical modes of thought, contrasting them to scientific modes of thought:

“Historians cannot ply their trade without a considerable capacity for thinking in general terms; but they need, in addition, peculiar attributes of their own: a capacity for integration, for perceiving qualitative similarities and differences, a sense of the unique fashion in which various factors combine in the particular concrete situation, which must at once be neither so unlike any other situation as to constitute a total break with the continuous flow of human experience, nor yet so stylised and uniform as to be the obvious creature of theory and not of flesh and blood. The capacities needed are rather those of association than of dissociation, of perceiving the relation of parts to wholes, of particular sounds or colours to the many possible tunes or pictures into which they might enter, of the links that connect individuals viewed and savoured as individuals, and not primarily as instances of types or laws.”

Isaiah Berlin, “The Concept of Scientific History,” in Concepts and Categories, p. 140

Every cognitive capacity that Berlin here credits to the historian can be equally well exercised in relation to the future as to the past (I should point out that, as far as I know, Berlin did not take up the problem of the relation of the historian to the future). Indeed, one of the weaknesses of futurism has been that futurists have not immersed themselves in these distinctively historical modes of thought; our conception of the future could greatly benefit from a capacity for integration and perceiving the relation of parts to wholes. I don’t think Berlin would ever have imagined his critique of scientific historiography as advice for futurists, but it could be profitably employed in developing history in an extended sense.

It is common for historians to invoke distinctively historical modes of thought, and I believe that this is a valid concern. Indeed, I would go farther yet. Human modes of thought are primarily temporal, and non-temporal modes of thought come very late in our history as a species in comparison to the effortless way we learn to think of time in subtle and sophisticated ways. For example, when one learns a language, one finds that one spends an inordinate amount of time attempting to master past, present, and future tenses — the tenses of our mother tongue are so fixed in our minds that any other schema strikes us as counterintuitive (and, interestingly, even those who attain fluency in another language or languages usually revert to their mother tongue for counting). But in order to communicate effectively we must master the logic of time as expressed in linguistic tenses. Human beings are inveterate planners, preparers, and schemers; our present is pervasively animated by a concern for the future. We are so taken up with our plans for the future that it is considered something of a “gift” to be able to “live in the moment.”

Many of Berlin’s examples of distinctively historical thought position the historian as attempting to explain historical change. The emphasis on describing change in history results in an indirect deemphasis of continuity, though continuity is arguably the overwhelming experience of time and history. It would be almost impossible for us to delineate all of the things that we know will happen tomorrow, and which we do not even bother to think of as predictions because they fall so far near certainty on the epistemic continuum of historical knowledge. All of the laws of science that have been discovered up to the present day will continue to be in effect tomorrow, and all of the events and processes that make up the world will continue to be governed by these laws of nature tomorrow. We could exhaust ourselves describing the nomological certainties of the morrow, and still not have exhausted the predictions we might have made. Thus it is we know that the sun will rise tomorrow, and we can explain how and why the sun will rise tomorrow. If you are an anchorite living in a cave, the sun will not rise for you, but you can nevertheless be confident that Earth will continue to orbit the sun while rotating, and that this process will result in the appearance of the sun rising for everyone else not so confined.

But our sciences that describe the laws of nature that govern the world are incomplete, and they are in particular incomplete when it comes to history. I have noted elsewhere that there is (as yet) no science of time, and it is interesting to speculate that the absence of a science of time may be related to a parallel absence of a truly scientific historiography or a science of civilization. Because we have no science of time, we have no formal concepts of time — or, rather, we have no concepts of time recognized to be formal concepts. I have argued elsewhere that the idea of the punctiform present is a formal concept of time, i.e., interpreted as a formal concept it can be employed in a formal theory of time which can illuminate actual time as an ideal, simplified model. But as soon as you try to interpret the idea of the punctiform present as an empirical concept you run into difficulties. Would it be possible to measure a dimensionless instant? The punctiform present is like a pendulum with a weightless string, frictionless fulcrum, and no air drag. No such pendulum exists in actual fact, but the ideal pendulum remains a useful fiction for us. Similarly, the punctiform present is a useful fiction for a formal science of time.

A truly (perhaps exhaustively) scientific historiography would not only employ the methods of the special sciences in the exposition of history, but would also incorporate a science of time that would allow us to be as definite about history to come as we can now be definite about our predictions for the natural world as governed by laws of nature. It is not difficult to imagine what Berlin would have thought of such an idea. Here is another quote from Berlin’s essay on scientific historiography:

“…the attempt to construct a discipline which would stand to concrete history as pure to applied, no matter how successful the human sciences may grow to be — even if, as all but obscurantists must hope, they discover genuine, empirically confirmed, laws of individual and collective behaviour — seems an attempt to square the circle.”

Isaiah Berlin, “The Concept of Scientific History,” in Concepts and Categories, p. 142

What Berlin here condemns as an attempt to square the circle is precisely my ideal in history, and it is what I called formal historiography in Rational Reconstructions of Time. A formulation of history in an extended sense would be a step toward a formal historiography.

While on one level I am interested in history as an intellectual discipline in its own right — history for history’s sake — and therefore I am interested in formal historiography as a sui generis discipline, I also have an ulterior motive in the pursuit of a formal historiography that can develop history in an extended sense. Such a formal historiography will be one tool in the interdisciplinary toolkit of future scientists of civilization, who must study civilization both in terms of its past and its future.

The Thomas Digges chart of a Copernican solar system from 1576.

The Thomas Digges chart of a Copernican solar system from 1576.

The full awareness of our sun being a star, and the stars being suns in their own right, was a development nearly coextensive with the entire history of science, from its earliest stirrings in ancient Greece to its modern form at the present time. During the Enlightenment there was already a growing realization of this, as can be seen in a number of scientific works of the period, but scientific proof had to wait for a few generations more until new technologies made available by the industrial revolution produced scientific instruments equal to the task.

bessel-and-parallax

The scientific confirmation of this understanding of cosmology, which is, in a sense, the affirmation of Copernicanism (as distinct from heliocentrism) came with two scientific discoveries of the nineteenth century: the parallax of 61 Cygni, measured by Friedrich Wilhelm Bessel and published in 1838, which was the first accurate distance measured to a star other than the sun, and the spectroscopy work of several scientists — Fraunhofer, Bunsen, Kirchhoff, Huggins, and Secchi, inter alia (cf. Spectroscopy and the Birth of Astrophysics) — which demonstrated the precise chemical composition of the stars, and therefore showed them to be made of the same chemical elements found on Earth. The stars were no longer immeasurable or unknowable; they were now open to scientific study.

Joseph von Fraunhofer invented the spectroscope, and first observed what are now called Fraunhofer lines.

Joseph von Fraunhofer invented the spectroscope, and first observed what are now called Fraunhofer lines.

The Ptolemaic conception of the universe that preceded this Copernican conception painted a very different picture of the universe, and of the place of human beings within that universe. According to the Ptolemaic cosmology, the heavens were made of a different material than the Earth and its denizens (viz. quintessence — the fifth element, i.e., the element other than earth, air, fire, and water). Everything below the sphere of the moon — sublunary — was ephemeral and subject to decay. Everything beyond the sphere of the moon — superlunary — was imperishable and perfect. Astronomical bodies were perfectly spherical, and moved in perfectly circular lines (except for the epicycles). Comets were a problem (i.e., an anomaly), because their elliptical orbits ought to send them crashing through the perfect celestial spheres.

This Ptolemaic cosmology largely satisfied the scientific, philosophical, moral, and spiritual needs of western thought from classical antiquity to the end of the Middle Ages, and this satisfaction presumably follows from a deep consonance between this conception of the cosmos and a metaphysical vision of what the world ought to be. Ptolemaic cosmology is the intellectual fulfillment of a certain kind of heart’s desire. But this was not the only metaphysical vision of the world having its origins (or, at least, its initial expression) in classical antiquity. Another intellectual tradition that pointed in a different direction was mathematics.

Mathematics was the first science to attain anything like the rigor that we demand of science today. It remains an open question to this day — an open philosophical question — whether mathematics is a science, one of the sciences (a science among sciences), or whether it is something else entirely, which happens to be useful in the sciences, as, for example, the formal propaedeutic to the empirical sciences, in need of formal structure in order to organize their empirical content. The sciences, in fact, get their rigor from mathematics, so that if there were no mathematical rigor, there would be no possibility of scientific rigor.

Euclid provided the model of formal thought with his axiomatization of geometry. Legend has it that there was a sign over the door of Plato's Academy stating, 'Let no one enter here who has not studied geometry.'

Euclid provided the model of formal thought with his axiomatization of geometry. Legend has it that there was a sign over the door of Plato’s Academy stating, ‘Let no one enter here who has not studied geometry.’

Mathematics has been known since antiquity as the paradigm of exact thought, of precision, the model for all sciences to follow (remembering what science meant to the ancients, which is not what it means today: a demonstrative science based on first principles), and this precision has been seen as a function of its formalism, which is to say its definiteness, it boundedness, its participation in the peras. Despite this there was yet a recognition of the infinite (apeiron) in mathematics. I would go further, and assert that, while mathematics as a rigorous science has its origins in the peras, it has its telos in the apeiron. This is a dialectical development, as we will see below in Proclus.

An early copy of Euclid's Elements, which axiomatically systematized geometry.

An early copy of Euclid’s Elements, which axiomatically systematized geometry.

Proclus expresses the negative character of the infinite in his commentary on Euclid’s Elements:

“…the infinite is altogether incomprehensible to knowledge; rather it takes it hypothetically and uses only the finite for demonstration; that is, it assumes the infinite not for the sake of the infinite, but for the sake the infinite.”

Proclus, A Commentary on the First Book of Euclid’s Elements, translated, with an introduction and notes, by Glenn R. Morrow, Princeton: Princeton University Press, 1992, Propositions: Part One, XII, p. 223. This whole section is relevant, but I have quoted only a brief portion.

There is no question that the apeiron appeared on the inferior side of the Pythagorean table of opposites, but it is also interesting to note what Proclus says earlier on:

“The objects of Nous, by virtue of their inherent simplicity, are the first partakers of the Limit (περας) and the Unlimited (ἄπειρον). Their unity, their identity, and their stable and abiding existence they derive from the Limit; but for their variety, their generative fertility, and their divine otherness and progression they draw upon the Unlimited. Mathematicals are the offspring of the Limit and the Unlimited…”

Proclus, Commentary on the First Book of Euclid, Prologue: Part One, Chap. II

Here the apeiron appears on an equal footing with the peras, both being necessary to mathematical being. “Mathematicals” are born of the dialectic of the finite and the infinite. Both of these elements are also found (hundreds of years earlier) in the foundations of geometry. As the philosophers produced proofs that there could be no infinite number or infinite space, Euclid spoke of lines and planes extended “indefinitely” (as “apeiron” is usually translated in Euclid). Even later when the Stoics held that the material world was surrounded by an infinite void, this void had special properties which distinguished it from the material world, and indeed which kept the material world from having any relation with the void. The use of infinities in geometry, however, even though in an abstract context, force one to maintain that space locally, directly before one, is essentially of the same kind as space anywhere else along the infinite extent of a line, and indeed the same as space infinitely distant. All spaces are of the same kind, and all are related to each other. This constitutes a purely formal conception of the uniformity and continuity of nature. One might interpret the subsequent history of science as redeeming, through empirical evidence, this formal insight.

proclus-on-euclid

The infinite is the “internal horizon” (to use a Husserlian phrase) and the telos of mathematical objects. Given this conception of mathematics, the question that I find myself asking is this: what was the mathematical horizon of the Greeks? Did the idea of a line or a plane immediately suggest to them an infinite extension, and did the idea of number immediately suggest the infinite progression of the series, or were the Greeks able to contain these conceptions within the peras, using them not unlike we use them, but allowing them to remain limited? Did ancient mathematical imagination encompass the infinite, or must such a conception of mathematical objects (as embedded in the infinite) wait for the infinite to be disassociated from the apeiron?

husserl-quote

The wait was not long. While the explicit formulation of the mathematical infinite had to wait until Cantor in the nineteenth century, Greek thought was dialectical, so regardless of the nature of mathematical concepts as initially conceived, these concepts inevitably passed into their opposite numbers and grew in depth and comprehensiveness as a result of the development of this dialectic. Greek thought may have begun with an intellectual commitment to the peras, and a desire to contain mathematics within the peras, consequently an almost ideological effort to avoid the mathematical infinite, but a commitment to dialectic confounds the demand for limitation. It is, then, this dialectical character of Greek thought that gives us the transition from purely local concepts to a formal concept of the uniformity of nature, and then the transition from a formal conception of uniformity to an empirical conception of uniformity, and this latter is the cosmological principle that is central to contemporary cosmology.

The cosmological principle brings us back to where we started: To say that the sun is a star, and every star a sun, is to say that the sun is a star among stars. Earth is a planet among planets. The Milky Way is a galaxy among galaxies. This is not only a Copernican idea, it is also a formal idea, like the formal conception of the uniformity of nature. (In A Being Among Beings I made a similar about biological beings.) To be one among others of the same kind is to be a member of a class, and to be a member of a class is to be the value of a variable. Quine, we recall, said that to be is to be the value of a variable. This is a highly abstract and formal conception of ontology, and that is precisely the importance of the formulation. This is the point beyond which we can begin to reason rigorously about our place in the universe.

We require a class of instances before we can draw inductive inferences, generalize from all members of this class, or formalize the concept represented by any individual member of that class. This is one of the formal presuppositions of scientific thought never made explicit in the methodology of science. We could not formulate the cosmological principle if we did not have a concept of “essentially the same,” because the “same” view that we see looking in any direction in the universe is not identically the same, but rather essentially the same. Of any two views of the universe, every detail is different, but the overview is the same. The cosmological principle is not a generalization, not an inductive inference from empirical evidence; it is a formal idea, a regulative idea that makes a certain kind of cosmological thought possible.

cosmological-principle

Formal principles like this are present throughout the sciences, though not often recognized for what they are. Bessel’s observations of 61 Cygni not only required industrialized technology to produce the appropriate scientific instruments, these observations also presupposed the mathematics originating in classical antiquity, so that the nineteenth century scientific work that proved the stars to be like our sun (and vice versa) was predicated upon parallel formal conceptions of universality structured into mathematical thought since its inception as a theoretical discipline (in contradistinction to the practical use of mathematics as a tool of engineering). Formal Copernicanism preceded empirical Copernicanism. Without that formal component of scientific knowledge, that scientific knowledge would never have come into being.

A Fine-Grained Overview

5 December 2016

overview-and-detail

Constructive and Non-Constructive Perspectives

Whenever I discuss methodology, I eventually come around to discussing the difference between constructive and non-constructive methods, as this is a fundamental distinction in reasoning, though often unappreciated, and especially neglected in informal thought (which is almost all human thought). After posting Ex Post Facto Eight Year Anniversary I realized that the distinction that I made in that post between detail (granularity) and overview (comprehensivity) can also be illuminated by the distinction between the constructive and the non-constructive.

Two two pairs of concepts can be juxtapositioned in order to show the four permutations yielded by them. I have done the same thing with the dual dichotomies of nomothetic/ideographic and synchonic/diachronic (in Axes of Historiography) and with weak panspermia/strong panspermia and theological/technological (in Is astrobiology discrediting the possibility of directed panspermia?). The table above gives the permutations for the juxtaposition of detail/overview and constructive/non-constructive.

In that previous post I identified my theoretical ideal as a fine-grained overview, combining digging deeply into details while also cultivating an awareness of the big picture in which the details occur. Can a fine-grained overview be attained more readily through constructive or non-constructive methods?

In P or Not-P I quoted this from Alain Connes:

“Constructivism may be compared to mountain climbers who proudly scale a peak with their bare hands, and formalists to climbers who permit themselves the luxury of hiring a helicopter to fly over the summit.”

Changeux and Connes, Conversations on Mind, Matter, and Mathematics, Princeton, 1995, p. 42

This image makes of constructivism the fine-grained, detail-oriented approach, while non-constructive methods are like the overview from on high, as though looking down from a helicopter. But it isn’t quite that simple. If we take this idea of constructivists as mountain climbers, we may extend the image with this thought from Wittgenstein:

“With my full philosophical rucksack I can climb only slowly up the mountain of mathematics.”

Ludwig Wittgenstein, Culture and Value, p. 4

And so it is with constructivism: the climbing is slow because they labor under their weight of a philosophical burden. They have an overarching vision of what logic and mathematics ought to be, and generally are not satisfied with these disciplines as they are. Thus constructivism has an overview as well — a prescriptive overview — though this overview is not always kept in mind. As Jean Largeault wrote, “The grand design has given way to technical work.” (in the original: “Les grands desseins ont cédé la place au travail technique.” L’intuitionisme, p. 118) By this Largeault meant that the formalization of intuitionistic logic had deprived intuitionism (one species of constructivism) of its overarching philosophical vision, its grand design:

“Even those who do not believe in the omnipotence of logic and who defend the rights of intuition have acceded to this movement in order to justify themselves in the eyes of their opponents. As a result we find them setting out, somewhat paradoxically, the ‘formal rules of intuitionist logic’ and establishing an ‘intuitionistic formalism’.”

…and in the original…

“Ceux-la memes qui ne croient pas a la toute-puissance de la logique et qui défendent les droits de l’intuition, ont du, eux aussi, céder au mouvement pour pouvoir se justifier aux yeux de leurs adversaires, et l’on a vu ainsi, chose passablement paradoxale, énoncer les ‘regles formelles de la logique intuitioniste’ et se constituer un ‘formalisme intuitioniste’.”

Robert Blanché, L’axioimatique, § 17

But intuitionists and constructivists return time and again to a grand design, so that the big picture is always there, though often it remains implicit. At very least, both the granular and the comprehensive conceptions of constructivism have at least a passing methodological familiarity, as we see in the table above, on the left side, granular constructivism with its typical concern for the “right” methods (which can be divorced from any overview), but also, below that, the philosophical ideas that inspired the constructivist deviation from classical eclecticism, from Kant through Hilbert and Brouwer to the constructivists of our time, such as Errett Bishop.

These two faces of methodology are not as familiar with non-constructivism. In so far as non-constructivism is classical eclecticism (a phrase I have taken from the late Torkel Frazén), a methodological “anything goes,” this is the granular conception of non-constructivism that consists of formal methods without any unifying philosophical conception. This much is familiar. Less familiar is the possibility of a non-constructive overview made systematic by some unifying conception. The idea of a non-constructive overview is familiar enough, and appears in the Connes quote above, but it this idea has had little philosophical content.

There is, however, the possibility of giving non-constructive formal methodology an overarching philosophical vision, and this follows readily enough from familiar forms of non-constructive thought. Cantor’s theory of transfinite numbers, and the proof techniques that Cantor formulated (and which remain notorious among constructivists) is a rare example of non-constructive thought pushed to its limits and beyond. Applied to a non-constructive overview, the transfinite perspective suggests that a systematically non-constructive methodology would insistently seek a total context for any idea, by always contextualizing any idea in a more comprehensive setting, and pursuing that contextualization to infinity. Thus any attempt to think a finite thought forces us to grapple with the infinite.

A fine-grained overview might be formulated by way of a systematically non-constructive methodology — not the classical eclecticism that is an accidental embrace of non-constructive methods alongside constructive methods — that digs deep and drills down into details by non-constructive methods that also furnish a sweeping, comprehensive philosophical vision of what formal methods can be, when that philosophical vision is not inspired to systematically limit formal methods (as is the case with constructivism).

Would the details that would be brought out by a systematically non-constructive method be the same fine-grained details that constructivism brings out when it insists upon finitistic proof procedures? Might there be different kinds of detail to be revealed by distinct methods of granularity in formal thought? These are elusive thoughts that I have not yet pinned down, so examples and answers will have to wait until I have achieved Cartesian clarity and distinctness about non-constructive methods. I beg the reader’s indulgence for my inadequate formulations here. Even as I write, ideas appear briefly and then disappear before I can record them, so this post is different from what I imagined as I sat down to write it.

Here again I can appeal to Wittgenstein:

“This book is written for such men as are in sympathy with its spirit. This spirit is different from the one which informs the vast stream of European and American civilization in which all of us stand. The spirit expresses itself in an onwards movement, building ever larger and more complicated structures; the other in striving after clarity and perspicuity in no matter what structure. The first tries to grasp the world by way of its periphery — in its variety; the second at its center — in its essence. And so the first adds one construction to another, moving on and up, as it were, from one stage to the next, while the other remains where it is and what it tries to grasp is always the same.”

Ludwig Wittgenstein, Philosophical Remarks, Foreword

These two movements of thought are not mutually exclusive; it is possible to build larger structures while always trying to grasp an elusive essence. It could be argued that anything built on uncertain foundations will come to naught, so that we must grasp the essence first, before we can proceed to construction. As important as it is to attempt to grasp an elusive essence, if we do this, we risk the intellectual equivalent of the waiting gambit.

eight-ball

Last month, November 2016, marked the eight year anniversary for this blog. My first post, Opening Reflection, was dated 05 November 2008. Since then I have continued to post, although less frequently of late. I have become much less interested in tossing off a post about current events, and more interested in more comprehensive and detailed analyses, though blog posts are rarely associated with comprehensivity or detail. But that’s how I roll.

It is interesting that we have two distinct and even antithetical metaphors to identify non-trivial modes of thought. I am thinking of “dig deep” or “drill down” on the one hand, and, on the other hand, “overview” or “big picture.” The two metaphors are not identical, but each implies a particular approach to non-triviality, with the former implying an immersion in a fine-grained account of anything, while the latter implies taking anything in its widest signification.

Ideally, one would like to be both detailed and comprehensive at the same time — formulating an account of anything that is, at once, both fine-grained and which takes the object of one’s thought in its widest signification. In most cases, this is not possible. Or, rather, we find this kind of scholarship only in the most massive works, like Gibbon’s Decline and Fall of the Roman Empire, or Mario Bunge’s Treatise on Basic Philosophy. Over the past hundred years or so, scholarship has been going in exactly the opposite direction. Scholars focus on a particular area of thought, and then produce papers, each one of which focuses even more narrowly on one carefully defined and delimited topic within a particular area of thought. There is, thus, a great deal of very detailed scholarship, and less comprehensive scholarship.

Previously in Is it possible to specialize in the big picture? I considered whether it is even possible to have a scholarly discipline that focuses on the big picture. This question is posed in light of the implied dichotomy above: comprehensivity usually comes at the cost of detail, and detail usually comes at the cost of comprehensivity.

Another formulation of this dichotomy that brings out other aspects of the dilemma would to ask if it is possible to be rigorous about the big picture, or whether it is possible to be give a detailed account of the big picture — a fine-grained overview, as it were? I guess this is one way to formulate my ideal: a fine-grained overview — thinking rigorously about the big picture.

While there is some satisfaction in being able to give a concise formulation of my intellectual ideal — a fine-grained overview — I cannot yet say if this is possible, or if the ambition is chimerical. And if the ambition for a fine-grained overview is chimerical, is it chimerical because finite and flawed human beings cannot rise to this level of cognitive achievement, or is it chimerical because it is an ontological impossibility?

While an overview may necessarily lack the detail of a close and careful account of anything, so that the two — overview and detail — are opposite ends of a continuum, implying the ontological impossibility of their union, I do know, on the other hand, that clear and rigorous thinking is always possible, even if it lacks detail. Clarity and rigor — or, if one prefers the canonical Cartesian formulation, clear and distinct ideas — is a function of disciplined thinking, and one can think in a disciplined way about a comprehensive overview. If one allows that a fine-grained overview can be finely grained in virtue of the fine-grained conceptual infrastructure that one employs in the exposition of that overview, then, certainly, comprehensive detail is possible in this respect (even if in no other).

I could, then, re-state my ambition as formulated in my opening reflection such that, “my intention in this forum to view geopolitics through the prism of ideas,” now becomes my intention to formulate a fine-grained overview of geopolitics through the prism of ideas. But, obviously, I now seldom post on geopolitics, and am out to bag bigger game. This is, I think, implicit in the remit of a comprehensive overview of geopolitics. F. H. Bradley famously said, “Short of the Absolute God cannot stop, and, having reached that goal, He is lost, and religion with Him.” We might similarly say, short of big history geopolitics cannot stop, and, having reached that goal, it is lost, and political economy with it.

Eusocial insect colonies achieve an impressive degree of social differentiation and specialization without the kind of intelligence found among mammals. Some scientists call this collective behavior social intelligence.

Eusocial insect colonies achieve an impressive degree of social differentiation and specialization without the kind of intelligence found among mammals. Some scientists call this collective behavior ‘social intelligence.’

In a couple of blog posts, Is encephalization the great filter? and Of Filters, Great and Small, I argued that encephalization is the great filter — clearly implying that this is a single filter that is more significant than another filters, and that encephalization is the great filter. The “great filter” is an idea due to Robin Hanson, according to whom, “The Great Silence implies that one or more of these steps [to visible colonization] are very improbable; there is a ‘Great Filter’ along the path between simple dead stuff and explosive life. The vast vast majority of stuff that starts along this path never makes it. In fact, so far nothing among the billion trillion stars in our whole past universe has made it all the way along this path.”

In the second of the two blog posts noted above, Of Filters, Great and Small, I considered the different possible structures that filters might take, and this is a more nuanced view of the great filter that departs from the idea that a single element of the great filter is uniquely responsible for the great silence and the Fermi paradox. The journey to higher forms of emergent complexity seems to be robust, and therefore likely to have been repeated elsewhere, but it is also a long journey of later emergent complexities multiply supervening upon earlier emergent complexities. This structure of emergent complexities over time is itself a structure more complex than any one of the emergent complexities taken in isolation. In so far as we understand the great filter in this content, we understand a more nuanced view than the idea of one step among many steps along this journey being the unique hurdle to the aggressive expansion of life in the universe, and therefore its visible traces discoverable through cosmology.

Even given this more nuanced view of the great filter, later forms of emergent complexity will be less common than earlier forms, and within the structure of the great filter we can identify particular emergent complexities where the iterated structure falters. If we place this stalling point at exponential encephalization, we might find a universe filled with complex life, but with few or no other intelligent species capable of building a civilization. This is the sense in which I wish my claim that encephalization is the great filter to be understood.

Recently I have had reason to revisit the idea that encephalization is the great filter, and this is primarily due to having read The Social Conquest of Earth by E. O. Wilson, which emphasizes the role of eusociality in the construction of complex societies. I think that Wilson is right about this. Wilson notes that eusociality has emerged on Earth only a handful of times, making it a rare form of emergent complexity: “Eusociality arose in ants once, three times independently in wasps, and at least four times — probably more, but it is hard to tell — in bees.” (p. 136) We can compare this rarity of eusociality as an adaptation to the rarity of intelligence as an adaptation.

The insects that have achieved robust eusociality — perhaps I should say arthropods — are very different from mammals. We must go back more than 500 million years to the split between protostomes and dueterostomes to find the last common ancestor of the two. With the arthropods we share being bilaterally symmetrical, but the split between us — hence the split between our brains and central nervous systems (CNS) — is about as old as the split between mammals and molluscs: chordata, mollusca, and arthropoda are distinct phyla. On the one hand, we know from a recent fossil find something about the CNS of the earliest chordates, which we thus have in common with most other terrestrial animalia (cf. How early a mind?); on the other hand, we also know that neural structures have evolved independently on Earth (cf. The ctenophore genome and the evolutionary origins of neural systems), so that we might speak of neurodiversity among terrestrial animalia. Different brains, when sufficiently complex, are substrates for different forms of emergent consciousness, i.e., different forms of mind.

It is not only dramatically different kinds of minds that might give rise to dramatically different forms of encephalization, and thus intelligence and civilization. Part of the differentness of eusocial insects is their reproductive specialization, which goes along with a genetic structure of a colony in which the superorganism of the colony benefits overall from a majority of individuals not reproducing. This is also dramatically different from human societies. It has been objected to Wilson’s thesis of the eusociality of human beings that human beings are not eusocial, but rather prosocial, and that human cooperative societies cannot be compared to insect cooperative societies because there is no parallel to reproductive specialization among human beings. This, I think, is an unnecessarily narrow conception of eusociality. All we have to do is to recognize that eusociality can take multiple forms (as minds and intelligence can take multiple forms, supervening upon multiple distinct neural structures), some of which involve reproductive specialization and some of which do not, in order for us to recognize human cooperative societies as eusocial.

The most developed brain of the molluscs is that of the octopus, a solitary hunter. Octopi have been hunting in the depths of the sea for hundreds of millions of years, and, apparently, they have never experienced competition on the basis of intelligence, and, perhaps because of this, have never experienced an encephalization event. (Recently in How early a mind? I quoted E. O. Wilson to the effect that, “A Homo sapiens level of intelligence can arise only on land, whether here on Earth or on any other conceivable planet.” ) So octopi have a respectable level of intelligence, but are far from being eusocial. The eusocial insects have a much less powerful brain than octopi or mammals, but they did make the breakthrough to eusociality. Only human beings made the breakthrough to both eusociality and high individual intelligence.

Since reading Wilson on the eusociality of human societies, I can come to think that human civilization is what happens when eusociality coincides with intelligence. Termite mounds and bee hives are what happens when eusociality coincides with insect-level intelligence. And this observation of the interaction of eusociality and intelligence immediately suggests two possible counterfactuals to human civilzation, which I will sketch below. Understand that, in this context, when I use the term “human civilization” I am using this is in its most generic signification, covering all the many different human civilizations that have existed, i.e., the class of all human civilizations (which is the class of all known civilizations constructed by a biological being both eusocial and intelligent).

I noted above that we can employ a conception of eusociality less narrow than that restricted to eusocial insects with reproductive specialization. Similarly, the other element in civilization — intelligence — ought also to be construed broadly. Many different kinds of intelligence interacting with many different kinds of eusociality suggest many different possibilities for civilization distinct from the class of human civilizations. At the present time I am not going to consider kinds of eusociality and intelligence as much as degrees of eusociality and intelligence, and I will assume that the insect transition to reproductive specialization represents eusociality taken to a higher degree than eusociality has progressed in human beings. Similarly, I will assume that human intelligence represents a higher degree of intelligence than now-extinct branches of the genus homo, i.e., our ancestors with lower degrees of encephalization and lower intelligence.

From these assumptions about degrees of eusociality and intelligence, two counterfactual classes of civilization are suggested:

High Eusociality/Low Intelligence

A species might be less intelligent than human beings (i.e., possess a lower degree of encephalization) but more eusocial than human beings, and be able to build a civilization.

Low Eusociality/High Intelligence

A species might be more intelligent than human beings (i.e., possessing a higher degree of encephalization, or a thicker neocortex) but less eusocial than human beings, and be able to build a civilization.

This formulation has the virtue of existing human civilization embodying the principle of mediocrity: our eusociality and intelligence are balanced; we are not as eusocial or as individualistic as we might have been, and we are not as intelligence or as unintelligent as we might have been. We are in the “Goldilocks zone” of coinciding eusociality and intelligence, and this human “sweet spot” for civilization may account for the fact that civilization emerged independently in widely separated geographical regions, not as a result of idea diffusion, but rather as a consequence of independent invention.

In the High Eusociality/Low Intelligence class of civilizations, we would see somewhat individually intelligent beings capable of a high degree of cooperation through eusociality forming socieites (superorganisms) quite early in their history. We can see the degree to which bees and ants and termites can develop societies based on eusociality and an almost negligible individual intelligence; with a degree of eusociality approaching this, but in a species endowed with more cognitive capacity, cities might be built that look like something between a human city and a termite mound, and this might happen spontaneously. If this had happened with an earlier human ancestor — a counterfactual ancestor with greater eusociality than any actual human ancestor — it could have preempted the emergence of human civilization by occurring millions of years earlier.

In the Low Eusociality/High Intelligence class of civilizations, civilization may have come about at the level of scattered bands of hunter-gatherers, or, at least, human beings in small groups may have been able to develop science and technology without large social institutions such as governments, universities, and corporations, which discipline unruly human beings and make it possible for them to work cooperatively together. One can imagine that a more intelligent (counterfactual) species of the genus homo might have been sufficiently intelligent to pursue science at a much earlier period of its history, and one can imagine members of such a species coming together for scientific purposes much as our ancestors came together at Göbekli Tepe (which I first wrote about in The Birth of Agriculture from the Spirit of Religion) possibly for religious rituals, even before they gathered in settlements for agriculture.

Both counterfactual scenarios I have described above could have resulted in civilization on Earth emerging tens of thousands or hundreds of thousands of years earlier than it did in fact emerge. I suppose it would be equally possible to formulate counterfactuals in which different classes of civilization emerged much later.

Each of the three classes of civilizations considered here — moderate eusociality/moderate intelligence, high eusociality/low intelligence, and low eusociality/high intelligence — have distinct advantages and disadvantages, in terms of the viability of the civilization that results. However, cognitive capability begins to play a much greater role in civilization after industrialization when civilization becomes technological and scientific. If a given civilization can survive to make the breakthrough to science-driven technology, all other things being equal, the species with the greatest intelligence will have the greatest advantage in deploying science to further the ends of that species. I suspect that a high eusociality/low intelligence civilization would be stagnant, and possibly so stagnant that the breakthrough to industrialization never occurs. I also suspect that human beings were just smart enough to make that breakthrough, as indicated by the single point of origin of the industrial revolution. Short of that threshold, any civilization remains cosmologically invisible, exclusively bound to its homeworld, and incapable of long-term existential risk mitigation. This scenario is consistent with the great silence, and may constitute another approach to the Fermi paradox.

The research questions that follow from these considerations include: Are there intrinsic limits to eusociality among beings whose biology is not consistent with reproductive specialization? Are there intrinsic limits to intelligence for biological beings of known biochemistry? How do eusociality and intelligence interact biologically and ecologically? Does either constitute a check upon the other?

. . . . .

Cooperation among human beings has its limits -- as illustrated by the story of the Tower of Babel -- and one limit to cooperation is our level of eusociality.  With a higher or lower level of eusociality, civilization would have had a different structure.
