Review of Part I

In Part I of this series of posts on technological civilization, it was asked, What is technological civilization? And in the attempt to answer this question, a model of civilization was applied to the problem of technological civilization, it was asked whether technology can function as the central project of a civilization, and an inquiry was made into the idea of technology as an end in itself; from these inquiries preliminary conclusions were drawn, and the significance of these preliminary conclusions for the study of civilization were considered.

It was asserted in Part I that a technological civilization in the narrowest sense (a properly technological civilization) is a civilization that takes technology as its central project, and in a civilization that takes technology as its central project, the economic infrastructure and intellectual superstructure cannot remain indifferent to technology, so that technology must be assumed to be pervasively present throughout the institutional structure of a properly technological civilization. However, it was also determined that properly technological civilization are probably rare, and that the common usage of “technological civilizations” covers those cases in which technology is absent in the central project, or only marginally represented in the central project, but is pervasive in the economic infrastructure and the intellectual superstructure.

In this post, Part II of the series, we will further investigate what it means for technology to be pervasively present throughout the institutional structure of civilization, and how this pervasive presence of technology throughout society distinguishes technological civilizations from civilizations that employ technology but which we do not usually call technological.

The prehistory of technological civilization

Technological civilizations do not appear suddenly and without precedent, but have a deep history that long precedes civilization. Thus we must treat technological civilizations developmentally, and, as we shall see, comparatively; technological development and comparative measures are closely linked.

The prehistory of technological civilization is the history of technology prior to civilization, and the history of technology prior to civilization can be pushed back not only into human prehistory, but into pre-human history, and even the use of technology by other species. Whereas it was once a commonplace and human beings were the only tool-using species, we now know that many other species use tools. Perhaps the most famous example of this are the observations of chimpanzees in the wild stripping leaves from a branch, and then using this bare branch to extract termites from a termite mound, which are then consumed. Primate tool use (as well as primate modification of the environment that they inhabit) is now sufficiently recognized that there is a growing discipline of primate archaeology, which employs the methods of archaeology developed for studying the human past in order to study the material culture of non-human primates.

Other species have even been observed using fire, which is another instance of technology previously assumed to be unique to human beings. Australian Firehawks have been observed in the, “transport of burning sticks in talons or beaks,” intentionally spreading fire for purposes of fire foraging (cf. Intentional Fire-Spreading by “Firehawk” Raptors in Northern Australia by Mark Bonta, Robert Gosford, Dick Eussen, Nathan Ferguson, Erana Loveless, and Maxwell Witwer). The deep history of technology in the biosphere, then, recognizes that many species have used tools, and have done so for millions of years; the scope of technology is both larger and older than human history. In this context, the human use of technology is a continuous development of earlier tool use, bringing tools to a level of development and sophistication far beyond that of other species.

One of the unique features of human tool use (in so far as our present knowledge extends) is the production of durable tools that are used repeatedly over time, and, in some cases, continuously modified, as when a chipped stone or flint tool is used until it becomes dull, and then the edge is sharpened by additional chipping. Tool use by other species has not involved the production of durable tools used over time. However, if we interpret shelters as tools, then the nest of the weaver bird or the lodge of the beaver are durable constructions used over time and often repeatedly improved. (Shelter can be understood as a form of niche construction, and it would be an interesting inquiry to examine the relationship between niche construction and technology, but we will not explicitly consider this in the present context.)

Another unique feature of human tool use is the use of tools to make other tools. When a flint cutting edge is used to cut strips of bone and tendon that are then layered together to make a compound bow, this is the use of one tool to make another tool. The iteration of this process has led ultimately to the sophisticated tools that we manufacture today, and nothing like this has been seen in other species, even in other hominid species (though future investigations in archaeology may prove otherwise). Human ancestors used durable stone tools for millions of years, often with little or no change in the design and use of these tools, but the use of tools to make other tools seems to be restricted to homo sapiens, and perhaps also to the Neanderthals.

The point of this discussion of prehistoric technology is to emphasize that tools and technology are not only older than civilization, but also older than humanity, although humanity does bring tool development and use to a degree of complexity unparalleled elsewhere in terrestrial history. Given this deep history of tools in the biosphere, the late appearance of civilization in the past ten thousand years emerges in a context in which human technology had already reached a threshold of complexity unequaled prior to human beings. At its origin, civilization already involved durable tools of iterated manufacture. If this is what has been meant when we speak of “technological civilization,” then the very first civilizations were technological from their inception; in other words, technology according to this usage would provide no differentiation among civilizations because all civilizations are technological.

Charles Darwin approached the origin of civilization naturalistically, which was, in his time, the exception rather than the rule.

Darwin’s Thesis on the origin of civilization

Civilization, then, begins in medias res with regard to technology. Technology gets its start at the shallow end of an exponential growth curve, incrementally and with the simplest0 innovations. The emergence of distinctively human technologies represents an inflection point in the development of technology. This inflection point occurs prior to the advent of civilization, but civilization contributes to the acceleration of technological development. With civilization, more time and resources become available for technological development, and, as civilization expands, technology expanded and grew in power and sophistication.

The origins of civilization, like the origins of technology, are similarly simple and incremental. In an earlier post I posited what I called Darwin’s Thesis on the origin of civilization, or, more simply, Darwin’s Thesis, based on this passage from Darwin:

“The arguments recently advanced… in favour of the belief that man came into the world as a civilised being and that all savages have since undergone degradation, seem to me weak in comparison with those advanced on the other side. Many nations, no doubt, have fallen away in civilisation, and some may have lapsed into utter barbarism, though on this latter head I have not met with any evidence… The evidence that all civilised nations are the descendants of barbarians, consists, on the one side, of clear traces of their former low condition in still-existing customs, beliefs, language, &c.; and on the other side, of proofs that savages are independently able to raise themselves a few steps in the scale of civilisation, and have actually thus risen.”

Charles Darwin, The Descent of Man, Chapter V (I have left Darwin’s spelling in its Anglicized form.)

It may seem pointless to assert something as apparently obvious as Darwin’s thesis, but the state in which the study of civilization finds us (i.e., that it does not yet exist in anything like a scientific form) makes it necessary that we begin with the most rudimentary ideas and state them explicitly so that they can be understood to characterize our theoretical orientation, and can be tested against other similarly rudimentary ideas when we reach the point of being able to perceive that we are assuming these other ideas and that we therefore need to make these other ideas explicit also. Our understanding of civilization — like the origins of technology and civilization themselves — must begin simply and incrementally.

There is a characteristically amusing passage from Bertrand Russell in which Russell mentions beginning with assumptions apparently too obvious to mention:

“My desire and wish is that the things I start with should be so obvious that you wonder why I spend my time stating them. This is what I aim at because the point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it.”

Bertrand Russell, The Philosophy of Logical Atomism, 2, “Particulars, Predicates, and Relations”

Elsewhere, and in this case specifically in relation to history, Russell mentioned the rudimentary beginnings of scientific thought:

“…comparatively small and humble generalizations such as might form a beginning of a science (as opposed to a philosophy) of history.”

Bertrand Russell, Understanding History, New York: Philosophical Library, 1957, pp. 17-18

Perhaps Russell may have distinguished the scientific from the philosophical understanding of history such that philosophical understanding ends in paradox while scientific understand does not. In any case, whether we take Darwin’s Thesis to be too obvious to state, or to be a small and humble generalization (or both), it is at this level of simplicity that we must begin the scientific study of civilization.

The passage quoted above from Darwin makes reference to “barbarism” and “savagery,” which we today take to be evaluative terms with a strongly condescending connotation, but in Darwin’s time these were technical terms, and, moreover, they were technical terms related to a people’s level of technological development. These terms were very common in the late 19th and early 20th century, and subsequently fell out of use. In falling out of use, we have largely forgotten what these terms meant, and so there has been an prochronic misreading of older texts as though these terms were being used formerly as they are used today.

In my post Savagery, Barbarism, and Civilization I discussed the taxonomy of human development developed by Edward Burnett Tylor and expounded by Lewis Henry Morgan, which distinguished between savagery, barbarism, and civilization. For Tylor and Morgan, savagery extends through pre-pottery developments, barbarism from the invention of pottery to metallurgy, and civilization is reserved for societies that have a written language. This taxonomy is broken down in greater detail into eight stages of technological accomplishment — three stages of savagery, three of barbarism, and one of civilization (cf. Chapter I of Morgan’s Ancient Society).

Thus when Darwin wrote that savages have raised themselves by their own efforts a few degrees in the scale of civilization, what he meant was that hunter-gatherer nomads have, over time, developed technologies such as pottery, agriculture, herding, and metallurgy — something that most today would not dispute, even if they would not use the particular language that Darwin employed. Indeed, if Darwin were writing today he would himself employ different terminology, as the Tylor and Morgan terminology has been completely abandoned by the social sciences.

Edward Gibbon focused on the decline and fall of Rome, but he also noted that some technological achievements survived the process of decline he detailed.

Gibbon on the Continuity of Technology

Societies thus, following Darwin’s Thesis, begin in an uncivilized condition and raise themselves up through stages of technological development, and, following Tylor and Morgan, these stages can be quantified by the presence or absence of particular technologies. One might disagree concerning which particular technologies ought to be taken as markers of civilizational achievement, and yet still agree with the principle that technological development over time can be used to differentiate stages of development. One might, for instance, chose different representative technologies — say, the use of the bone needle to sew form-fitting clothing, the production of textiles, etc. It would be another matter to throw out the underlying principle.

Darwin also mentioned the possibility that, “Many nations… have fallen away in civilisation,” which implies that technological accomplishments can be lost. Implicit in this claim is the familiar idea of a cyclical conception of history. One might maintain that societies rise up in technological accomplishment, only to experience a crisis and to be returned to their original state, starting over from scratch in regard to technological development. We find an explicit argument against this in Edward Gibbon.

Gibbon is remembered as the historian of the decline and fall of the Roman Empire, and given Gibbon’s focus on declension it is especially interesting that Gibbon argued for the retention of technological achievement notwithstanding the collapse of social, political, and legal institutions. At the end of Volume 3 of The Decline and Fall of the Roman Empire Gibbon wrote a kind of summary, “General Observations On The Fall Of The Roman Empire In The West,” which includes Gibbon’s thoughts on the technological progress of civilization. Gibbon presents a view that is entirely in accord with common sense, but one that is rarely expressed, though Gibbon has expressed this view in a strong form that probably admits of important qualifications:

“The discoveries of ancient and modern navigators, and the domestic history, or tradition, of the most enlightened nations, represent the human savage, naked both in body and mind and destitute of laws, of arts, of ideas, and almost of language. From this abject condition, perhaps the primitive and universal state of man, he has gradually arisen to command the animals, to fertilize the earth, to traverse the ocean and to measure the heavens. His progress in the improvement and exercise of his mental and corporeal faculties has been irregular and various; infinitely slow in the beginning, and increasing by degrees with redoubled velocity: ages of laborious ascent have been followed by a moment of rapid downfall; and the several climates of the globe have felt the vicissitudes of light and darkness. Yet the experience of four thousand years should enlarge our hopes, and diminish our apprehensions: we cannot determine to what height the human species may aspire in their advances towards perfection; but it may safely be presumed, that no people, unless the face of nature is changed, will relapse into their original barbarism. The improvements of society may be viewed under a threefold aspect. 1. The poet or philosopher illustrates his age and country by the efforts of a single mind; but those superior powers of reason or fancy are rare and spontaneous productions; and the genius of Homer, or Cicero, or Newton, would excite less admiration, if they could be created by the will of a prince, or the lessons of a preceptor. 2. The benefits of law and policy, of trade and manufactures, of arts and sciences, are more solid and permanent: and many individuals may be qualified, by education and discipline, to promote, in their respective stations, the interest of the community. But this general order is the effect of skill and labor; and the complex machinery may be decayed by time, or injured by violence. 3. Fortunately for mankind, the more useful, or, at least, more necessary arts, can be performed without superior talents, or national subordination: without the powers of one, or the union of many. Each village, each family, each individual, must always possess both ability and inclination to perpetuate the use of fire and of metals; the propagation and service of domestic animals; the methods of hunting and fishing; the rudiments of navigation; the imperfect cultivation of corn, or other nutritive grain; and the simple practice of the mechanic trades. Private genius and public industry may be extirpated; but these hardy plants survive the tempest, and strike an everlasting root into the most unfavorable soil. The splendid days of Augustus and Trajan were eclipsed by a cloud of ignorance; and the Barbarians subverted the laws and palaces of Rome. But the scythe, the invention or emblem of Saturn, still continued annually to mow the harvests of Italy; and the human feasts of the Læstrigons have never been renewed on the coast of Campania.”

Edward Gibbon, The Decline and Fall of the Roman Empire, “General Observations On The Fall Of The Roman Empire In The West,” end of Chapter XXXVIII: Reign Of Clovis. Part VI.

Gibbon himself had detailed the extirpation of private genius and public industry in the case of the decline and fall of Rome, but he had also observed that, “…the more useful, or, at least, more necessary arts,” can survive on a local level which does not (or perhaps need not) experience dissolution even when larger social and political wholes fail and result in the extirpation of private genius and public industry on a larger scale. Gibbon concluded this summary as follows:

“Since the first discovery of the arts, war, commerce, and religious zeal have diffused, among the savages of the Old and New World, these inestimable gifts: they have been successively propagated; they can never be lost. We may therefore acquiesce in the pleasing conclusion, that every age of the world has increased, and still increases, the real wealth, the happiness, the knowledge, and perhaps the virtue, of the human race.”

Edward Gibbon, ibid.

In making the distinctions he did, Gibbon provided a relatively nuanced historical account of technological development, such that certain developments like the scythe would continue to be used even while more sophisticated manufactures fell out of production, and eventually out of use. Certainly this is what appears to have occurred with the decline of the industries of classical antiquity.

At some point in the ancient world, industry advanced to the point that it could produce artifacts like the Antikythera mechanism, and then at some point this industrial capacity was lost. One can speculate that the Antikythera mechanism was probably produced in the workshop of some city in which science, technology, and engineering had come together in a critical mass of knowledge and expertise to allow for the construction of such a device, and when Roman cities failed, this critical mass was scattered and the capacity to build devices like the Antikythera mechanism was lost. However, at the same time, the manorial estates and small villages to which urbanites fled when their cities ceased to function were able to keep lower levels of technology functioning. An estate or a village would have a forge at which iron sufficient for agricultural purposes could be produced, even if the ability to manufacture more sophisticated technologies was lost.

This idea of certain technologies being preserved in broadly-based human knowledge, in contradistinction to the technological accomplishments of gifted individuals or public institutions, I will call Gibbon’s Thesis on the Persistence of Technology, or, more simply, Gibbon’s Thesis. If contemporary civilization were to fail catastrophically, Gibbon’s Thesis would suggest to us that the heights of our technological accomplishments would be lost, but that technologies and techniques that could be locally produced and maintained, even without any particularly gifted individual or a larger socioeconomic structure, would persist — perhaps electric lights and basic telephone service, for example.

The Antikythera Mechanism

Technological Horizons

Darwin’s Thesis and Gibbon’s Thesis are theses on the origins and development of technological civilization, but the examples employed by Darwin and Gibbon do not bring us up to the level of technological accomplishment that we usually associate with the term “technological civilization,” though we could clearly associate their examples with nascent technological civilization, or embryonic technological civilization.

Gibbon’s Thesis can be used to define what I will call a horizon of technological development. I have previously discussed the archaeological use of the term “horizon” in Horizons of Spacefaring Civilizations, in which I quoted three definitions of horizon in archaeology, including David W. Anthony’s definition: “…a single artifact type or cluster of artifact types that spreads suddenly over a very wide geographic area.” While I have taken the term “horizon” from its use in archaeology, I have adapted it a bit (or more than a bit) for my own purposes. An artifact type may be an artistic style or a particular technology; in the present context we will only consider technologies and classes of technology that become common and hence widely represented in material culture.

The archaeological usage distinguishes horizon from tradition, and tends to view horizons as being of short duration (and traditions as being of long duration). I will use “horizon” to mean any relatively rapid expansion of some cluster of technologies, which may be the initial appearance of these artifact types, which may (but may not necessarily) remain common from that time forward, until their terminal horizon, if they disappear rapidly. For example, if human civilization were suddenly destroyed by a nuclear war, the technosignature of our EM spectrum radiation into to space would have a sudden terminal horizon when these EM signals ceased at about the same time.

The commonly used and understood technologies that Gibbon’s Thesis posits will survive the absence of gifted individuals and larger socioeconomic institutions are technological horizons of widely available technology that spread rapidly (though rapidity is relative to historical context) and which, if archaeologists were to excavate the appropriate layer, would be commonly represented in the material culture of a given time. When archaeologists dig up classical sites, they find pottery sherds everywhere; they find oil lamps; they find agricultural implements. To date, only one Antikythera mechanism has been found; it is the exception, and not the rule, so it represents a level of accomplishment, but not a horizon.

If a future archaeologist were to dig up the future remains of the present age, in what were industrialized nation-states there would be a horizon of electronic devices — computers, smart phones, DVD players — although outside the wealthy regions of the contemporary world these devices would be much less in evidence. And perhaps, in some technological enclaves, the ability to produce devices like this might continue even when a wider social order had failed. This is doubtful, however, so it may be necessary to reformulate Gibbon’s Thesis a little. Most of us today use technology that we do not understand, and we do not seem to be converging upon a society of engineers and technologists in which most people would understand (and be able to re-create) most of the technology they employ on a daily basis.

With this reflection, we have one possible way to distinguish proper technological civilizations: they are civilizations in which, because technology is the central project of the civilization, knowledge of technology is so widespread and so enthusiastically received that the technological horizon of the society is maintained at such a high level that even a small, local community could produce and maintain the advanced technologies they use on a daily basis.

If the ancient world had attained this kind of technological horizon, archaeologists would find devices like the Antikythera mechanism in every small town, and this kind of technology would have stayed in use and continued in development, rather than being lost of human memory. Our society today also is not at this technological horizon. Our most advanced technologies would be lost in a great social disruption, rather than continuing in use and development.

Those technologies that do persist in use throughout social disruptions also tend to continue in development, though that development may be very gradual. Gibbon cites the example of the scythe; we might also cite the example of the plow. From the first digging sticks employed at the dawn of agriculture to the mechanized plows of today, the plow has been in continual, gradual development for thousands of years. There is scarcely a period of human history in which plow technology did not experience some slight improvement, because it was a widely used technology, easily understood by those who used the technology, and so subject to continual minor improvement.

The Horizon of Industrialization and Technological Civilization

Agricultural civilization coincides with the horizon of agricultural technology. From a human perspective, the thousands of years of agricultural civilization is in no sense rapid or sudden, but from an archaeological, and even more so from a geological or paleontological perspective, the whole of agricultural civilization would represent a very thin layer in the geological record, a layer that in most cases would be lost due to other geological processes, but which is so widely present in the Earth that it could probably be found (especially if one knew what to look for).

Industrialized civilization coincides with the horizon of industrial technologies, and it is from the industrial technologies that our present advanced technologies are derived. Our present advanced technologies give us a hint of the technologies that might be available to a truly advanced civilization — say, a civilization that experienced the equivalent of our industrial revolution and then continued to develop for thousands of years, i.e., the development of industrial technologies on an historical order of magnitude equivalent to that of our experience of agricultural technologies. And this is probably what we intuitively have in mind when we use a term like “technological civilization.”

When industrialized civilization has endured for thousands of years, possibly with several minor disruptions, but not enough of a disruption to prevent the persistence of basic technologies (as per Gibbon’s Thesis), industrialized civilization, like agricultural civilization, will leave only a very thin and easily expungible layer in the Earth’s geological record. But this thin layer will be the industrial horizon, and, from the point of view of a future archaeologist who is digging up the Anthropocene, there won’t be much differentiation between the earliest part of this layer and the latest part of this layer, which latter is several thousand years beyond us yet. In this compactified history of industrial civilization, we are, for all practical purposes, indistinguishable from an advanced technological civilization.

Looking Ahead to Part III

Part II has been a bit of a detour into the origins and development of technological civilization, a departure from the more theoretical concerns about the institutional structure of technological civilizations introduced in Part I. However, this detour has allowed us to introduce and discuss Darwin’s Thesis, the Tylor-Morgan taxonomy, Gibbon’s Thesis, and the idea of technological horizons, which can then be employed in future installments for the exposition of further theoretical issues in the definition of technological civilization.

In Part III we will introduce more theoretical concepts to complement those of Part I, but which bear upon the development of technological civilization, unlike the theoretical concepts introduced in Part I which could be taken to characterize the structure of a civilization irrespective of its history or development.

The Biocentric Thesis

19 July 2016

Tuesday


The biocentric character of contemporary civilization is strikingly evident in aerial photographs.

The biocentric character of contemporary civilization is strikingly evident in aerial photographs.

The Centrality of Biology to Civilization

Beyond the formulation of the biological conception of civilization and the ecological conception of civilization, both of which employ concepts from biology, we can identify a particular thesis (or particular theses) addressing the centrality of biological relationships and biological entities to civilization (as we have known civilization to date). I have expressed the centrality of biology to civilization as the biocentric thesis.

Although I have not previously formulated the biocentric thesis explicitly (here I will attempt to do this) though I have used the idea many times. Previously I wrote about biocentric civilizations in From Biocentric Civilization to Post-biological Post-Civilization, Addendum on the Stages of Civilization, and Another Way to Think about Civilization, inter alia, without attempting to clarify my use of “biocentric,” while in The Biological Conception of Civilization and The Ecological Conception of Civilization I considered biologically-derived conceptions of civilization.

Even our mythologies have involved the close association of human beings with fellow biological beings, as in this depiction of the earthly paradise. ('The garden of Eden with the fall of man,' Peter Paul Rubens and Jan Brueghel the Elder, 1615)

On Being Biological

Let us begin with the basics: human beings, the progenitors of terrestrial civilization, are biological. Being ourselves biological entities, human life has been integral with the biological world from which it arose. We live by consuming other biological entities, and, when we die, our bodies decompose and their constituents are reintegrated with the biological world from which we sprang. When human beings began the civilizational project, we remained integral with the biological world, exapting it for our new-found purposes, which involved the tightly-coupled coevolutionary cohort of species that I employed as the biological conception of civilization. In western thought it as been traditional to oppose nature to culture, but, being biological, we understand our civilization by understanding ourselves, and we understand ourselves by understanding biology.

Biology is both an old and a young science. Plato had little use for biology, and in reading Plato’s dialogues one could be forgiven for supposing that the Greeks had ever lived in any condition other than a civilization in which nature is kept at a certain distance. Aristotle, on the contrary, was a careful observer of nature, thus we may say that biology as science goes back at least to Aristotle’s treatises The History of Animals, On the Parts of Animals, On the Motion of Animals, and On the Gait of Animals.

Biology in its contemporary form goes back to Darwin, from which time biology has rapidly advanced and is today a mature science, as sophisticated in its own way as particle physics. And while we do not usually think of the growing rigor and sophistication of a body of scientific knowledge as an exercise in introspection, in the case of biology we can think of it in this way — if only we have the hardihood to apply what we have learned from biology to ourselves and to our biologically-based civilization. Because we are biological beings, knowledge of biology is knowledge of ourselves.

In this photograph we not only see the human imprint on the landscape, but also the projection of human civilization into Earth orbit.

In this photograph we not only see the human imprint on the landscape, but also the projection of human civilization into Earth orbit.

Being Biological in an Astrobiological Context

Astrobiology is a very young science, but in so far as it takes up the torch of biology and extrapolates biological concepts to their ultimate cosmological context, astrobiology is simply a greatly expanded biology, and in this sense not a new science at all. In From an Astrobiological Point of View I characterized the emergence of astrobiology in this spirit of continuity as the fourth of four great revolutions in biology, the previous three revolutions being Darwinism, Mendelian genetics, and evolutionary developmental biology (better known as “evo-devo”).

In the context of astrobiology, understanding the conditions for life in the universe is a greatly expanded form of human introspection, in which an evolving body of scientific knowledge has the capability of demonstrating the cosmological context of human life. Once again, in understanding astrobiology we can better understand ourselves, if only we have the willingness to understand ourselves scientifically. Beyond understanding ourselves, astrobiology also holds the promise of better understanding our civilization. An astrobiological formulation of the biological conception of civilization would extrapolate this conception of civilization to a cosmological scope.

In Astrobiology is island biogeography writ large I suggested that spaceflight is to astrobiology as flight is to biogeography, which is an application of the principle that technology is the pursuit of biology by other means. Given technologically-enabled spaceflight (made possible by a technological civilization), terrestrial life can expand beyond Earth and beyond our planetary system to other worlds, just as the innovation of flight made it possible for terrestrial organisms (even those that do not fly) to establish themselves on distant, isolated islands — hence the analogy between biogeographical distribution patterns and astrobiological distribution patterns. This is still a biocentric paradigm, but extrapolated to cosmological scope.

Biocentric Theses

With these considerations of what it means to be a biological being in an astrobiological context, I will attempt an explicit formulation of weak and strong biocentric theses. All of these formulations involve what I have earlier called planetary endemism.

The Weak Biocentric Thesis

All civilizations during the Stelliferous Era begin as biocentric civilizations originating on planetary surfaces.

This thesis is “weak” because it addresses only civilizations during the Stelliferous Era. A corollary of the weak biocentric thesis excludes the possibility of any Stelliferous Era civilization that does not arise from biology, as follows:

Corollary of the Weak Biocentric Thesis

No civilizations during the Stelliferous Era existed prior to the advent of Stelliferous Era biota.

The weak biocentric thesis and its corollary implies a strong biocentric thesis, not limited to the Stelliferous Era:

The Strong Biocentric Thesis

All civilizations in our universe begin as biocentric civilizations originating on planetary surfaces.

The strong biocentric thesis also has a strong corollary:

Corollary of the Strong Biocentric Thesis

No civilizations existed in our universe prior to the biocentric civilizations of Stelliferous Era.

Both strong and weak biocentric theses and their corollaries entail that the emergent complexity of civilization arises from the previous emergent complexity of life, and, in their strongest formulations, that it could be no other way. This excludes the possibility that there exist forms of emergent complexity other than life — sufficiently distinct from life as we know it than any identification of this emergent complexity as life would be problematic — from which civilization might independently arise. This is a rather sweeping claim, and, though it is supported by our parochial knowledge of life and civilization on Earth, it would be quite a stretch to assert this for the universe entire. On the other hand, we would still want to entertain this possibility, as there may be universes in which the only emergent complexity upon which civilization can supervene is life, more or less as we know it.

If the Strong Biocentric Thesis and its corollary are true, then there are no pre-Stelliferous Era civilizations, and all post-Stelliferous Era civilizations are derived from Stelliferous Era civilizations having their origins in planetary endemism. Post-Stelliferous Era civilizations would include Degenerate Era civilizations, Black Hole Era civilizations, and Dark Era civilizations. This might be formulated as another thesis in turn.

According to this understanding of civilization, the Stelliferous Era is uniquely generative of civilizations. In so far as we understand civilizations to belong to a suite of emergent complexities, we might say instead that the Stelliferous Era is uniquely generative of emergent complexity. At least, we say that now, prior to the emergent complexities unique to the Degenerate Era. It seems likely, however, that at some point the universe will reach peak complexity, and after that point it will begin to decay, and emergent complexities will begin to disappear, one by one.

Earth-Moon-System

The Terrestrial Eocivilization Hypothesis and Darwin’s Thesis

The above is closely related to what I have previously called the Terrestrial Eocivilization Hypothesis, which I characterized as follows:

“I will call the terrestrial eocivilization hypothesis the position that identifies early civilization, i.e., eocivilization, with terrestrial civilization. In other words, our terrestrial civilization is the earliest civilization to emerge in the cosmos. Thus the terrestrial eocivilization hypothesis is the civilizational parallel to the rare earth hypothesis, which maintains, contrary to the Copernican principle, that life on earth is rare. I could call it the ‘rare civilization hypothesis’ but I prefer ‘terrestrial eocivilization hypothesis’.”

This might, more simply, be called the “priority thesis,” and is to be distinguished from the “uniqueness thesis,” i.e., that there is one and only one civilization in the universe, and that one is terrestrial civilization. Thinking over this again in retrospect, I realize that priority, uniqueness, and biocentricity can be distinguished. A civilization might be unique in virtue of being first (i.e., having priority), or by being the only civilization, or by being the last of all civilizations. Thus priority is only one form of uniqueness among others. And priority and uniqueness can both be distinguished from biocentricity: according the biocentric theses above, biocentric civilization has priority (at least during the Stelliferous Era) but it not necessarily unique in the universe, nor unique to Earth. Terrestrial civilization is a biocentric civilization, and it may also have priority and it may be unique.

The biocentric theses are also related to what I have called Darwin’s Thesis on the Origins of Civilization, according to which civilization emerges from non-civilization, much as naturalistic accounts of life hold that life emerges from non-life (sometimes called abiogenesis). Whereas the priority thesis (i.e., the terrestrial eocivilization hypothesis, that the earliest civilization is terrestrial civilization) is specific to Earth, Darwin’s thesis, like the biocentric theses above, can be applied universally without reference to the historical accidents of civilization on Earth (including its emergence, and whether this emergence was earlier than or later than any other emergence of civilization).

From a scientific standpoint, then, it is more important to determine the exact logical relationships between the biocentric theses and Darwin’s thesis, as the details of what happened on Earth belong to the accidents of cosmological history. As I said in my post on Darwin’s thesis, these ideas about civilization are rudimentary in the extreme, but since a science of civilization does not yet exist, we must begin with these simplest of concepts if we are ever to think clearly about civilization.

In the scientific study of civilization we are beginning at the beginning because there is no established body of scientific knowledge about civilization — much historical knowledge, to be sure, but no science of civilization, sensu stricto, and therefore no scientific knowledge sensu stricto — and this demands that we begin with the simplest and most obvious propositions about civilization. The simplest and most obvious propositions about civilization are such as most discussions of civilization would simply pass over in silence as necessary presuppositions, or which would be dismissed by hand-waving and the assertion, “It is obvious that…” We will take a different point of view. Only a mathematician would think that the Jordan curve theorem was an idea in need of proof, and only someone engaged in attempting to formulate a science of civilization would think asserting that civilization originates in a pre-civilized condition was a condition of civilization that requires discussion.

Our point of departure in this discussion will be what I call Darwin’s Thesis on the origins of civilization, or, more simply, Darwin’s Thesis. I call this Darwin’s Thesis (and called it such in my presentation “What kind of civilizations build starships?”) because of the following passage from Darwin about the origins of civilization:

“The arguments recently advanced… in favour of the belief that man came into the world as a civilised being and that all savages have since undergone degradation, seem to me weak in comparison with those advanced on the other side. Many nations, no doubt, have fallen away in civilisation, and some may have lapsed into utter barbarism, though on this latter head I have not met with any evidence… The evidence that all civilised nations are the descendants of barbarians, consists, on the one side, of clear traces of their former low condition in still-existing customs, beliefs, language, &c.; and on the other side, of proofs that savages are independently able to raise themselves a few steps in the scale of civilisation, and have actually thus risen.”

Charles Darwin, The Descent of Man, Chapter V (I have left Darwin’s spelling in its Anglicized form.)

Darwin was here taking the same naturalistic stance in regard to civilization that he had earlier taken in regard to biology. Darwin made biology scientific by making it a domain of research approached by way of methodological naturalism; prior to Darwin there was biology of a kind, but not any study of biology that could be reconciled with methodological naturalism. Darwin applied this same reasoning to civilization, and this is the reasoning we must apply to civilization if we are to formulate a science of civilization that can be reconciled with methodological naturalism.

As far as ideas about civilization go, this is extremely basic. However, I will again stress the need to begin a science of civilization with the most basic and rudimentary propositions possible. While this is a proposition so rudimentary as to be mundane, there can be no more interesting question for the science of civilization than that of the origin of civilization (the question of the end of civilization is equally interesting, but I wouldn’t say it is more interesting).

While the simplest theses on civilization seem so mundane as to be uninteresting, they can nevertheless be deductively powerful in their application. We can only address the longevity of a civilization, for example, once we have established a point in time at which civilization begins, and counting forward in whatever temporal units we care to employ up to its demise (which also must be defined, if the civilization in question has come to an end), or up to the present day (if the civilization in question is still in existence).

According to Darwin’s Thesis, then, civilization is descended from a prior savage or barbaric condition (not terms we would likely employ today, but certainly terms we still understand). How are we to characterize this pre-civilized condition of humanity? What constitutes the non-civilization that preceded civilization?

A somewhat discerning distinction, albeit one with moral overtones, was made between savagery, barbarism, and civilization. Like the “three age” system of prehistory — stone age, bronze age, iron age — we still find traces of these distinctions in contemporary thought. Here is how I described it previously:

“Edward Burnett Tylor proposed that human cultures developed through three basic stages consisting of savagery, barbarism, and civilization. The leading proponent of this savagery-barbarism-civilization scale came to be Lewis Henry Morgan, who gave a detailed exposition of it in his 1877 book Ancient Society… A quick sketch of the typology can be found at Anthropological Theories: Cross-Cultural Analysis. One of the interesting features of Morgan’s elaboration of Tylor’s idea is his concern to define his stages in terms of technology. From the ‘lower status of savagery’ with its initial use of fire, through a middle stage at which the bow and arrow is introduced, to the ‘upper status of savagery’ which includes pottery, each stage of human development is marked by a definite technological achievement. Similarly with barbarism, which moves through the domestication of animals, irrigation, metal working, and a phonetic alphabet.”

Elsewhere I suggested that the non-civilization prior to civilization could be called proto-civilization. I just re-read my post on proto-civilization and now I find it inadequate, but I still endorse at least this much of what I said there:

“In the case of civilization, a state-of-affairs existed long before the idea of civilization was made explicit. But in projecting the idea of civilization backward in history, we already have the idea suggested by a particular cultural milieu, and the question becomes whether this idea can be applied further than the context in which it was initially proposed.”

This would be one methodology to employ: take the concept of civilization as it has been elaborated and seek to apply it to past social structures; determining at what point this concept no longer applies gives a point in time for the origin of civilization. This could be called the “retroactive method.”

Given the far greater archaeological data we possess than we possessed at the time the concept of civilization was first formulated, this method has new information to work with that it did not have at the time of its formulation. This is one of the points that I attempted to make, however poorly I did so, in my post on proto-civilization: we have an enormous amount of archaeological data on the Upper Paleolithic and Early Neolithic in the Old World, which is usually described in terms of “cultures” rather than “civilizations.” But when European explorers of the Early Modern period came to the New World, they encountered peoples that had social institutions that we today call civilizations, though these civilizations were closer to the “Stone Age” of the Old World than to the early civilizations of Egypt and Mesopotamia (to take to paradigm cases of civilization).

An alternative to the retroactive method would be to study the artifacts of the past on their own merits, to construct a definition of civilization on the basis of the earliest known human societies (on the basis of their material culture), and then apply this conception of civilization forward in time (for lack of a better term I will call this the proactive method, simply to contrast it to the retroactive method). It is arguable that some archaeologists do in fact follow this method, but I don’t know of anyone who has explicitly advanced this procedure as desirable (much less as necessary), although it does bear some resemblance to the implicit formalism of the cultural processual school in archaeological thought.

Both retroactive and proactive methods incorporate obvious problems that derive from parachronic distortions of evidence (the most obvious parachronism is the familiar idea of an anachronism, i.e., a survival from the past preserved into the present, where it is obviously out of place; the contrary parachronic distortion is that of projecting the present into the past).

To pull back from the provincial considerations of civilization studied by archaeology to date — that is to say, exclusively terrestrial civilizations — we can further develop the idea of Darwin’s Thesis in a cosmological context. Once we do this, we immediately understand that we have been asking questions focused on a particular set of conditions that are characteristic of civilizations during the Stelliferous Era, and our ideas worked out for terrestrial civilization (civilizations of planetary endemism during the Stelliferous Era) may not apply more generally to the largest scales of civilization achieved (or which may yet be achieved) in the cosmos.

Civilizations during the Degenerate Era may possess a different character due to their need to derive energy flows from sources other than stellar flux, which latter defines the conditions of the origins of civilization from intelligent biological agents during the Stelliferous Era, which might also be called the Age of Planetary Endemism. If the Degenerate Era begins with the universe having been exhaustively settled or inhabited by life and civilization, this densely inhabited universe not only would prevent the emergence of new civilizations, but also would mean an end to this living cosmos of starlight. In this case the Degenerate Era begins with what I have called the End-Stelliferous Mass Extinction Event (ESMEE), when widely distributed life and civilization of the Stelliferous Era, primarily supported by energy flows from stellar flux (and concentrated on planetary surfaces), comes to an end as the stars wink out one by one.

The cohort of emergent complexity that survives this transition is likely to be a post-civilization successor institution that is (by this time in the evolution of the universe) further removed from the origins of civilization than we are today removed from the origin of the universe. At this point, the origins of emergent complexity will be a distant question, largely inapplicable to contemporaneous concerns, and the central question will be what of the Stelliferous Era can survive into the Degenerate Era, and how it can perpetuate itself in a universe converging on heat death.

Would these civilizations of the Degenerate Era be newly originating civilizations, or would they be derivative from civilizations of the Stelliferous Era? The obvious answer would seem to be that these civilizations would be derivative, except that over such cosmological spans of time the concept of civilization (and the threshold of what constitutes a civilization) is likely to evolve as much as, if not more than, civilization itself. As civilization develops, and a greater degree of science, technology, and intellectual achievement is believed to be indispensable to what constitutes civilization, civilization may be redefined as something close to prevailing conditions, and everything prior to this is redefined as proto-civilization. For example, civilization today might be considered unimaginable without the conveniences of modern life, and everything prior is consigned to barbarism. This reasoning can be extended to hold that civilization is unimaginable without fusion energy, without strong AI, without interstellar travel, and so on. All of this is entirely consistent with Darwin’s Thesis, which holds regardless of whether we consider the Upper Paleolithic to be utter savagery, or 2016 to be utter savagery.

If we consciously make an effort to formulate and to retain a comprehensive conception of civilization, that is not continually revised forward in time in the light of the later developments of civilization, we can avoid the above problem, and it is this approach that gives us longer ages for our civilization today. I have often mentioned that it was once commonplace, and perhaps still commonplace, to fix the origins of civilization with the origins of written languages (i.e., the origins of the “historical period” sensu stricto), but scientific historiography has been slowly chipping away at the distinction between history and prehistory until it is no longer tenable. Hence I identify the origins of civilization with the emergence of cities during or shortly after the Neolithic Agricultural Revolution, which makes our civilization about ten thousand years old, rather than five thousand years old.

As our archaeological knowledge of the past improves, we may be able to set quantifiable conditions for the origins of civilization (say, a number of cities with a given population size, or a particular degree of sophistication in metallurgy, which latter seems to me to mark the ultimate origins of technological civilization). Again, Darwin’s Thesis is entirely in accord with this method also. Moreover, I think that this method gives a greater degree of independence to the determination of the origins of civilization, as it would also give us metrics by which we could determine the independent origin of a new civilization, say, even in the Degenerate Era, if this were to prove possible (which we really don’t know at present).

Beyond these concerns, and beyond the immediate scope of this post, we may need to posit a condition for the continuity of civilization — say, e.g., that metallurgical technological never lapses below a certain threshold — so that once given Darwin’s Thesis and some definition of civilization, we can determine when a civilization has originated de novo, and when a civilization is an evolutionary mutation of an earlier civilization, or a developmental achievement of an earlier civilization, rather than something new in history. This applies whether we take the threshold of achievement to be the smelting of copper or the building of starships. For example, if a civilization can smelt copper (or better), and never loses this technological capacity, it retains a minimal degree of continuity with the first civilization capable of this achievement, when an unbroken continuity of this capacity can be shown from the origins of this technology forward to some arbitrary date in the future.
