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.

An Explanatory Mechanism for Aggressively Expanding Civilizations
Any emergent complexity that adds itself to the ultimate furniture of the universe can be, on the one hand, the basis of further emergent complexities, while on the other hand it can function as a selection pressure upon the other furniture of the universe, including earlier and later iterations of emergent complexity. Now, that sounds very abstract — indeed, I could express this idea even more abstractly in the language of ontology — so let me attempt to provide some illustrative examples. When biology emerged from the geochemical complexity of Earth, biology eventually gave rise to further emergent complexities (consciousness, technology, civilization), but biology also began to shape the geochemical context of its own emergence. Biochemistry emerged from geochemistry, thus biochemistry has always been, ab initio, in coevolution with the geochemistry upon which it supervenes.
Life, then, coevolved with geology, as life now coevolves with later emergent complexities, which means that, in the case of human beings, human life coevolves with the habitat it has made for itself — Earth of the anthropocene and our civilization (cf. Intellectual Niche Construction). This point has been made by Wilson and Lumsden:
“[The] high level of human mental activity creates culture, which has achieved a life of its own beyond the ordinary limits of biology. The principal habitat of the human mind is the very culture that it creates.”
Edward O. Wilson and Charles J. Lumsden, Promethean Fire: Reflections on the Origin of Mind, Cambridge and London: Harvard University Press, 1983, p.
We might distinguish between relationships of tightly-coupled coevolution and loosely-coupled coevolution, with the familiar instances of coevolution — such as pollinating bees and flowers — qualifying as tightly-coupled, while those evolutionary relationships not usually recognized as coevolutionary qualify as loosely-coupled — for example, geochemistry and biochemistry, although the scale at which we make our comparison will be crucial to determining whether the coupling is tight or loose. “Coevolution” is another way of saying that each party to the coevolutionary relationship acts as a selection pressure on the other, so we make the distinction between tightly-coupled coevolution and loosely-coupled coevolution in order to differentiate between selection pressures, some of which are immediate and enduring (tightly-coupled), and some of which are distant and only sporadically influential (loosely-coupled).
Now that civilization has established itself as an emergent complexity on Earth, civilization may serve as the springboard for further emergent complexities, but it also has emerged as a new selection pressure upon the life that gave rise to civilization, while the geology of Earth and the terrestrial biosphere are, in turn, a selection pressure on civilization. Terrestrial (planetary) civilization may come to act as a selection pressure upon other emergent complexities yet to appear, which will also act as a selection pressure on terrestrial civilization, and these emergent complexities are likely to be emergent from civilization. A spacefaring civilization that encompasses (at first) multiple worlds of a planetary system, multiple planetary systems of multiple stars, or multiple galaxies, would be one form of emergent complexity that could arise from planetary civilization.
Among the immediate and enduring selection pressures on spacefaring civilizations will be the distribution of exploitable resources in space, as well as the other spacefaring civilizations with which such a civilization is in competition for these resources (these other spacefaring civilization themselves being an emergent complexity originating from other planetary civilizations derived from other biospheres). There may also be selection pressures from emergent complexities that we do not yet understand, and which we have not yet identified. These two selection pressures — distribution of resources and competition with other spacefaring civilizations — will shape (perhaps have shaped) the origins, evolution, distribution, and fate of spacefaring civilizations. Spacefaring civilizations will be in a tightly-coupled coevolutionary relationship with the cosmological distribution of resources (matter and energy) and the efforts of other spacefaring civilizations to also dominate these resources. Let us consider this more carefully.
When I wrote my post on Social Stratification and the Dominance Hierarchy I included a diagram (reproduced above; also see Group Dynamics) illustrating the selection pressures that lead to a dominance hierarchy in social animals. The diagram distinguished among scarce, limited, and abundant resources. Scarce resources lead to cooperation; sufficiently abundant resources can eliminate competition. In the case of limited resources, these resources can be scattered or concentrated. Scattered resources lead to competition in speed, while concentrated resources lead to competition in aggressiveness, and thence to a dominance hierarchy. The dominance hierarchy among human beings, which in civilization we call social stratification, implies that the resources significant to human beings have been scarce and concentrated.
If we confine our interest in human access to resources only to Earth, we can readily distinguish between regions where resources are sufficiently concentrated that they can be defended, and regions where resources are scattered, cannot be defended, and are therefore the object of competition in speed rather than aggressiveness. (We can also distinguish different social systems that have arisen shaped by the differential distribution of resources.) If we pull back from this geographical scale and consider the question from the perspective of a spacefaring civilization, the whole of Earth, our homeworld, is a concentrated and defensible locus of resources, but the cosmos on the whole represents an extreme scattering, over interstellar and intergalactic distances, of limited or scarce resources. This scattering of limited resources, in contradistinction to the concentrated and defensible resources of the homeworld of any intelligence species, ought to have the result of spacefaring civilizations defending their homeworld while competing for resources with other spacefaring civilizations, not through competition in aggressiveness, but through competition in speed.
Competition in aggressiveness for the resources of spacefaring civilization may be excluded by the scattering of these resources, so that we are not likely to see the emergence of a galactic empire, crushing under the boot heels of its storm troopers the aspirations to freedom, dignity, and equality of intelligent species throughout the galaxy. However, competition in speed for limited resources distributed on a cosmological scale may well be the primary selection pressure on spacefaring civilizations, and competition in speed ought to entail the rapid cosmological expansion of these civilizations.
Elsewhere I have mentioned the papers of S. Jay Olson (cf. Big Time, The Genesis Project as Central Project, and Second Addendum on the Genesis Project as Central Project: Invasive Species) concerning what Olson calls “aggressively expanding civilizations,” which embody rapid expansion on a cosmological scale. Here is Olson’s characterization of such as scenario:
“An ‘aggressive expansion scenario’ is a proposed cosmological phenomenon… whereby a subset of advanced life appears at random throughout the universe and expands in all directions, saturating galaxies and utilizing resources as they go… We also assume that all aggressive expanders will be of the same behaviour type, i.e. they all expand with the same velocity v in the local comoving frame, and the expanding spherical front of galaxy colonization leads to observable changes a fixed time T after the front has passed by.”
“Estimates for the number of visible galaxy-spanning civilizations and the cosmological expansion of life,” S. Jay Olson, International Journal of Astrobiology, Cambridge University Press, 2016, pp. 2-3, doi:10.1017/S1473550416000082
Competition in speed among spacefaring civilization would mean a focus on maximizing v for the expanding spherical front of galaxy colonization.
Citing Bostrom and Omohundro on the nature of superintelligent AI (presumptively the heir of our technological civilization, but see the final sentence below quoted from Olson, as he addresses this as well), Olson writes:
“From an independent field of study, it has been argued that resource acquisition is one of the ‘basic drives’ of a generic superintelligent AI. This means, in essence, that a sufficiently powerful AI will tend to use extreme expansion and resource acquisition as a means of maximizing its utility function, unless it is explicitly and carefully designed to avoid such behavior… even if advanced alien species tend to be monks who have forsaken all worldly gain, the accidents involving insufficiently careful design of an artificial superintelligence are potentially one of the largest observable phenomena in the universe, when they occur. The word ‘civilization’ is not really the best description of such a thing, but we will use it for the sake of historical continuity.”
We can see that competition in speed for limited resources provides an explanatory mechanism for the existence and expansion of aggressively expanding civilizations. Spacefaring civilizations that successfully compete for resources on a cosmological scale endure over cosmological scales of time, and perhaps leave a legacy in the form of a universe transformed sub specie civilizationis. Spacefaring civilizations that fail to expand go extinct, and leave no observable legacy. Whether there is room for more than one aggressively expanding civilization in any one universe, or whether this expansion takes place on scale of time sufficient to foreclose the opportunity of expansion to any rival civilizations, remains an open question. Once a universe is saturated with life, no other life, and no other civilization emergent from other life, would have an opportunity to appear, unless or until a cosmological scale extinction event created such an opportunity (which could be furnished by sufficiently violent gamma ray bursts).
The above considerations pose other interesting questions that could be taken up as research questions in the study of spacefaring civilization. How are we to distinguish between scarce and limited resources on a cosmological scale? Might the closely packed stars of globular clusters and galactic centers constitute limited resources, while diffuse spiral arms and the outer portions of elliptical galaxies constitute scarce resources? At what threshold of availability should we distinguish between matter and energy being scarce or limited? This may be a problem contingently decided by the technologies of spacefaring not yet known to us. That is to say, if technologically mature civilizations find interstellar travel (or intergalactic travel) somewhat routine, then we may regard cosmological resources as scattered and limited, and more concentrated areas such as mentioned (globular clusters and galactic centers) might pass over a threshold such that they would be considered concentrated — thus there would be the possibility of galactic empires competing on aggressiveness for defensible resources. If, on the other hand, interstellar (or intergalactic) travel is always difficult, then the universe presents, at best, limited resources, and perhaps scarce resources. In the case of scarce resources, there would be a window of opportunity for cooperation among spacefaring civilization for the effective and efficient exploitation of these resources.
If, as on the surface of Earth (and relative to a planetary civilization), cosmological resources are distributed unevenly, then the distribution of civilizations will mirror the distribution of resources — not only in extent, but also in character, with concentrated regions producing civilizations competing on aggression, and diffuse regions producing civilizations competing on speed. On a sufficiently large scale, uneven distribution of cosmological resources would violate the cosmological principle, which is a cornerstone of contemporary cosmology. However, on the smaller scales (especially galactic scales) that would confront early spacefaring civilizations, the differential of resources between concentrated stellar regions and diffuse steller regions may be sufficient to differentiate regions of a galaxy given over to competition on speed for cosmological resources and regions of the same galaxy given over to competition on aggressiveness for cosmological resources. With the position of Earth in a spiral arm of the Milky Way, we inhabit a region of relatively diffuse distribution of stars, so that any nascent spacefaring civilizations with which we would be in competition would be competition in speed. It is therefore in our interest to reach the stars as soon as possible, or, by declining competition, reconcile ourselves to the existential risk of being shut out of the possibility of being a civilization relevant to the galaxy.
It may be that civilizations in regions of diffuse and therefore limited resources naturally understand their dilemma and consequently focus upon spacecraft speed (which has always been a preoccupation of those engaged in the speculative engineering of interstellar capable spacecraft), while civilizations in regions of more concentrated and therefore defensible resources intuit their relative ease of travel and focus instead on aggressive domination of their region of space, and the technology that would make such aggressive domination possible. Thus a civilization may already begin to be shaped by the selection pressures of its galactic neighborhood even as a nascent spacefaring civilization. An obvious instantiation of this phenomenon would be a single planetary system in which more than one planet produced life and civilization. These multiple civilizations expanding into a single planetary system would immediately be in conflict over the resources of that planetary system. In our exploration of our own planetary system, we have not had to compete with another civilization, and so our earliest spacecraft have gone into space without armor or armaments. We have a free hand in expanding into our planetary system; that may not be true for all nascent spacefaring civilizations, and it may not be true for us at spacefaring orders of magnitude beyond our planetary system.

A biological being among biological beings
A human being is a being among beings, and moreover a biological being among biological beings. We come to an awareness of ourselves, and of what we are, in a biological context. Biophilia, then, is a default consequence of being biological and finding oneself in a biological content; biophilia is a cognitive bias of biological beings. (Previously I considered the relationship between our biological nature and our biological bias in Biocentrism and Biophilia.) From both our biocentrism and our biophilia follows biocentric civilization, which I formulated in terms of the biocentric thesis, so it is natural that I would next attempt to formulate a technocentric thesis, as I have often contrasted biocentric and technocentric conceptions.
Until quite recently there was no possibility of pursing a non-biophilic bent, i.e., of pursuing a technocentric bent. Over the past several thousand years of human civilization, individual human beings had a limited opportunity to immerse themselves into the human world of civilization, and this civilization has been predominantly and pervasively biocentric. Since the Industrial Revolution, however, after which both agriculturalism and pastoralism became economically marginal, and the adoption of technology greatly increased, the ability to separate oneself from biocentric institutions has increased proportionately, but the individual has remained himself a biological being, tied to the biological world through existential needs for personal sustenance. Thus our being biological has repeatedly brought us back to our biological origins. If civilization were to fail, we could still return to an almost exclusively biocentric context and — at least for those who survived this traumatic transition — life would go on.
The emergence of a technological milieu following the industrial revolution suggests the possibility of a technocentric civilization that is the successor to biocentric civilization. Indeed, we may even understand the emergence of a fully technocentric civilization as the telos of industrialized civilization. We can formulate this in greater generality, as this process may hold for any civilization whatsoever that originates as a civilization of planetary endemism and makes the transition to a technological civilization.
Should the intelligent (biological) agents that build a civilization cease to be biological and become, for example, technological instead of biological, over time those intelligent agents could grow apart from their biocentric origins, and the social institutions in which these intelligent agents participate will become increasingly less biocentric. Biocentricity, then, is a function of biological origins, i.e., biocentrism is a consequence of being biological (as I put it in The Biocentric Thesis), and biophilia is an expression of biocentricity. As a technological civilization grows away from its biocentric origins, it is likely to become less biophiliac over time, which will in turn allow for greater expression of technophilia.
An explicit formulation of the technocentric thesis
Let us try to give these ideas a more explicit formulation:
The Technocentric Thesis
Any fully technocentric civilization has evolved from a previous biocentric civilization by descent with modification.
…which implies its corollary formulated in the negative…
No civilization originates as a technocentric civilization.
By a “biocentric civilization” I mean a civilization that exemplifies the biocentric thesis. I have formulated a strong biocentric thesis (all civilizations in our universe begin as biocentric civilizations originating on planetary surfaces) and a weak biocentric thesis (all civilizations during the Stelliferous Era begin as biocentric civilizations originating on planetary surfaces), each of which has a corollary formulated in the negative. The technocentric thesis could also be given strong and weak formulations, e.g., all technocentric civilizations in our universe evolve from biocentric civilizations (strong) and all technocentric civilizations during the Stelliferous Era evolve from biocentric civilizations (weak). The weaker formulation is in each case constrained by temporal parameter while the stronger formulation is unconstrained.
The mechanism by which a technocentric civilization evolves from a biocentric civilization I call replacement, and replacement can be formulated as the replacement thesis:
The Replacement Thesis
All technocentric civilizations begin as biocentric civilizations and are transformed into technocentric civilizations through the replacement of biological constituents with technological constituents.
This in turn implies a negative formulation as its corollary:
Replacement Thesis Corollary
No technocentric civilization originates as a technocentric civilization, but emerges by replacement from a biocentric civilization of planetary endemism.
How far can replacement go? We can already see in our own industrialized civilization partial replacement, but can there be a complete replacement of biological constituents by technological constituents? For any civilizations originating in intelligent biological organisms, it is unlikely that living organisms could ever be completely eliminated, but they may be rendered superfluous for all practical purposes (i.e., superfluous to civilization).
The argument from consciousness
It would be possible to construct a scenario in which biology can never be completely eliminated as a constituent of civilization. Consider the following scenario, which I will call the argument from consciousness, based on the indispensability of consciousness to civilization and the unknown parameters of machine consciousness.
The Argument from Consciousness
I will assume that there is such a thing as consciousness, that human beings are conscious at least some of the time, and that this human consciousness plays a significant role in human existence and in the civilizations built by human beings. (It is necessary to make these rudimentary stipulations because it is not unusual to find consciousness dismissed, or called an “illusion,” or to see its role in the world minimized or marginalized.)
The view is prevalent, perhaps even dominant, in AI circles such that anything that can pass the Turing test must be called conscious. There is a degree of mutual reinforcement between this common view among AI researchers and the tacit positivism that continues to influence the development of contemporary science, which consigns consciousness of the sphere of metaphysics and thus rules out in principle any metaphysical entity that is consciousness. I will not here attempt to make a case for consciousness as a metaphysical entity, but I will assume, for the purposes of what follows, that a principled refusal to consider consciousness is a barrier to understanding human behavior, including the behavior of building civilizations.
Since we do not yet know what consciousness is, and we cannot produce a scientific account of consciousness, we do not know what the conditions of consciousness are. If we had a scientific theory of consciousness that allowed us to quantify consciousness by taking meaningful measures of consciousness, any putative consciousness, whether generated by a mechanism or by biology, natural or modified or fully synthetic, could be tested by such measures of consciousness and objectively determined to be conscious or not. We do not as yet possess any such science, nor can we take any such measurements.
Human and animal consciousness constitute existence proofs of the possibility of consciousness arising by natural means, and thus consciousness ought to be amenable to study by methodological naturalism, and also to replication. It is possible that consciousness can only be produced by biological means, i.e., it is possible that machine consciousness cannot be generated. The existence proof of consciousness provided by biological beings is not an existence proof of machine consciousness. Now, I personally think that machine consciousness will eventually come about, but we will not know that this is possible until it has been achieved.
Even if machine consciousness is impossible, it would still be possible to engineer consciousness by biological means, employing some variation on existing biological substrates of consciousness, or producing consciousness by way of synthetic or artificial biology. In this case, a civilization (or post-civilizational social institution) that preserves consciousness, or desires to preserve consciousness, will not be able to become purely technocentric in the sense of entirely eliminating biology, though the biology that is retained may be entirely subordinated to technical means and technical institutions. A civilization that retained consciousness through such biological means, but entirely within a technocentric context, could be called a technocentric civilization in which biology was ineradicable.
The argument from consciousness is merely an argument (and not a proof of anything), because the same absence of a science of consciousness that would allow us to take objective measures of consciousness is the absence of a science that would make it possible to prove either that consciousness can inhere in different kind of substrates (biological or mechanical, for example), or that consciousness can only be generated through biological means. Until we have a science of consciousness, we can advance this line of argumentation only through existence proofs, i.e., proofs of concept.
Even then, even given building a conscious machine, without a science of consciousness we would have no way to rigorously and objectively compare and contrast human consciousness with machine consciousness. One way to resolve this dilemma is the Turing test, as noted above, but no one who has any degree of scientific curiosity could be satisfied with cutting the Gordian knot of consciousness rather than unraveling it.
One of the virtues of explicitly formulating one’s ideas as theses (or as arguments), as in the above, is that one can then turn to the explicit criticism of these theses, especially to the task of unpacking the assumptions embedded in the theses. Another virtue of explicit formulations is that they can be explicitly falsified. The existence of a civilization not derived from biological complexity emergent on a planetary surface would falsify the biocentric thesis.
These explicit formulations, then, are not be taken as definitive formulations. I do not consider the biocentric thesis, the technocentric thesis, or the replacement thesis to be in any sense definitive, but rather to be a point of departure in an analysis of the nature of civilization taken in its broadest signification and extrapolated to a cosmological scale. Thus I hope to return to each of these theses in order to tease out their assumptions in order to analytically approach the intuitive conception of civilization with which I began.

27 July 2016
In The Biocentric Thesis I gave an explicit formulation of the idea that civilizations of the Stelliferous Era originate in the actions of biological agents — actually, I gave two formulations, a weak and a strong, each with a corollary. What I failed to explicitly note in that post was that, in explicitly formulating the biocentric thesis, the idea of biocentricity is not confined to describing the biocentric thesis. In other words, we can identify as “biocentric” some state-of-affairs (presumably a civilization, or, more narrowly, an institution) regardless whether this state-of-affairs exemplifies the biocentric thesis. Thus the concept of the biocentric has a much wider scope than the biocentric thesis specifically.
It is worthwhile to make this distinction because the biocentric thesis is a particular idea about the origin of civilization (an extrapolation of Darwin’s thesis to astrobiological scope) while the idea of the biocentric, being of greater scope, has much wider applicability. If the biocentric thesis is true, that is to say, if all civilizations during the Stelliferous Era begin as biocentric civilizations originating on planetary surfaces (or, in its strong form, if all civilizations in our universe begin as biocentric civilizations originating on planetary surfaces), then biocentrism is not merely a feature of the human condition, it is the condition from which any and all civilizations originate (i.e., it is the common condition of eocivilization).
What is the human relationship to biocentrism beyond a narrowly conceived biocentric thesis on the origins of civilization? In my post Astrobiology Thought Experiment I wrote:
“…I have been trying to get at the human affinity to the rest of life on Earth, and trying to get at it in a primarily visceral sense in order to get around the hopeless tangle of rationalization and cognitive bias that we have painstakingly erected around the idea of humanity.”
What I called “the human affinity for the rest of life on Earth” is also known as biophilia. E. O. Wilson’s initial exposition of the idea of biophilia defined the term as meaning, “…the innate tendency to focus on life and lifelike processes.” This appears on the very first page of his book Biophilia. Elsewhere, in his book The Diversity of Life, Wilson has defined biophilia as, “…the connections that human beings subconsciously seek with the rest of life.”
In formulating the idea of biophilia Wilson already anticipated the extrapolation of biophilia beyond terrestrial life. (Though Wilson’s term biophilia has rapidly gained currency and has been widely discussed, his original vision embracing a biophilia not limited to Earth has not enjoyed the same level of interest.) Also on the first page of Biophilia is this brief reflection on extraterrestrial life:
“From infancy we concentrate happily on ourselves and other organisms. We learn to distinguish life from the inanimate and move toward it like moths to a porch light. Novelty and diversity are particularly esteemed; the mere mention of the word extraterrestrial evokes reveries about still unexplored life, displacing the old and once potent exotic that drew earlier generations to remote islands and jungled interiors.”
Wilson, E. O., Biophilia: the Human Bond with Other Species, Cambridge and London: Harvard University Press, 2003, p. 1.
It seems likely that we would naturally extrapolate both our biophilic and biophobic reactions to any extraterrestrial life we may find. However, it is also likely that, in our encounters with extraterrestrial life in the future, there may be instances in which we cannot as clearly distinguish between the animate and the inanimate as we can with terrestrial life. Our biophilic intuitions may need to be educated and augmented if they are to applied beyond terrestrial life, just as our mathematical intuitions are educated and augmented when we learn advanced mathematical concepts that were no part of our intuitive endowment of mathematical knowledge (we can cite geometrical intuition as an instance of the latter). Unlike the example of educating our mathematical intuitions, however, we cannot educate and augment our biophilic and biophobic reactions without actually traveling to other biospheres and learning directly about other lifeforms, preferably in their native habitats. In other words, progress in biology is ultimately predicated upon progress in space travel. This is implicit in the very idea of astrobiology.
An interest in life as yet unexplored implies the possibility of xenophilia as a special case of biophilia. Wilson seems to unproblematically assume that this is the case, but I have regarded this as an open question. For example, in Terrestrial Bias: Thought Experiments I wrote:
“Is life itself, regardless of its origins, of value to our biophilic minds, or are our anthropogenic minds so focused on differential survival and reproduction of homo sapiens that life itself is an abstract idea that can find no purchase in our sentiments? How far does biophilia extend? Is biophilia really only terrestrial biophilia? Is xenophilia possible for terrestrially evolved minds?”
We can we a bit more systematic about this: we can distinguish between biophilia in a narrow sense and biophilia in an extended sense, and the meaning of biophilia can be extended in more than one way. Biophilia in its narrowest sense is the affinity that human beings have for other terrestrial life. The generalization of this narrow sense of biophilia would be human affinity for all life, wherever that life may be found (as implied by E. O. Wilson). The formalization of the narrow sense of biophilia would be the affinity that any intelligent agent would feel for the biota of its homeworld, and from this formalizaton we can deduce the possibility of a particular intelligent species with its affinity for its particular homeworld (and this is a distinct concept than the purely formal concept of any species’ affinity for its homeworld). The formalization of the generalization of human biophilia would be affinity that any intelligent biological being would have for any life to be found in the universe. These are the permutations of biophilia, and each permutation may be regarded as an open question inviting further research.
Biophilia in the extended sense of the formalization of human biophilia (the affinity that any biological being would have for the biota of its homeworld) can be taken as a foundational posit of cognitive astrobiology, as predictable in shaping minds as natural selection is predictable in shaping bodies. Biophilia is the cognitive expression of biocentrism, and in so far as biocentrism is likely to typify any intelligent biological being, any intelligent biological being is likely to embody the same kind of biophilia found among human beings. In this sense, biophilia is a central phenomenon of cognitive astrobiology.
However, we can also posit that any intelligent agent that builds a technological civilization, and eventually a spacefaring civilization by technological means, will have, to some degree, marginalized native biophilia to the extent that this is necessary in order for a class of persons in this civilization to be fully immersed in a technological milieu. I take this latter condition to be a sine qua non of the development of advanced technological capabilities; perhaps this idea — i.e., the idea of at least one class of persons under the umbrella of a larger society to be immersed in a technological milieu — demands independent analysis and exposition. This I will reserve for a future post.

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.
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.
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.
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.
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.

How briefly can a socioeconomic state of affairs endure and still constitute a distinct and identifiable civilization? To phrase the question in another way, how finely can we parse the concept of civilization? Though this is a question of some theoretical interest, I ask this question now because of recent remarks by President of the European Council Donald Tusk. Tusk was interviewed by the German publication Bild on the topic of the pending referendum on whether Britain should leave the European Union (which latter has been given the unfortunate name “Brexit”). Tusk said the following in this interview:
The leave campaign contains a very clear message: “Let us leave, nothing will change, everything will stay as before”. Well, it will not. Not only economic implications will be negative for the UK, but first and foremost geopolitical. Do you know why these consequences are so dangerous? Because in the long-term they are completely unpredictable. As a historian, I am afraid this could in fact be the start of the process of destruction of not only the EU but also of the Western political civilization.
And in the original German…
„Die Kampagne für den Brexit hat eine sehr klare Botschaft: ,Lasst uns austreten. Nichts wird sich ändern, alles wird bleiben wie immer.’ Nun, das ist falsch. Nicht nur wirtschaftlich, sondern vor allem geopolitisch wäre es ein Rückschlag für Großbritannien. Warum ist das so gefährlich? Weil niemand die langfristigen Folgen vorhersehen kann. Als Historiker fürchte ich: Der Brexit könnte der Beginn der Zerstörung nicht nur der EU, sondern der gesamten politischen Zivilisation des Westens sein.“
Bild, Nikolaus Blome und Kai Diekmann, EU-Ratspräsident Donald Tusk über die Brexit-Gefahr „Unsere Feinde werden Champagner trinken
There are two interesting qualifications that Tusk makes to his sweeping pronouncement on the beginning of the end of European civilization: “as a historian” (“Als Historiker”) and “Western political civilization” (“politischen Zivilisation des Westens”). I assume that Tusk is making the qualification “as a historian” in order to emphasize that he is not speaking as a politician, or in some other capacity, in this context. (Indeed, Tusk studied history at the University of Gdańsk.) The other qualification — instead of simply invoking “western civilization” he specified “western political civilization” — is more difficult to interpret. One might speculate that he attaches the idea of politics to civilization as a hedge, suggesting that political civilization might unravel, but that is not necessarily the end of civilization simpliciter. However, one probably shouldn’t try to read too much into this qualification.
Can we speak of a Eurozone civilization, or has the Eurozone been too ephemeral in historical terms to qualify as a civilization? I would have no hesitation in referring to a Eurozone civilization, and, in so far as there is a Eurozone civilization, the unraveling of the Eurozone project that could follow from British withdrawal could well begin the unraveling of Eurozone civilization. But let us take a closer look at short-lived civilizations.
I have previously written about Soviet Civilization (cf. Addendum on Failed Civilizations and The Genocide of Homo Sovieticus), which only endured about seventy years, and unraveled when the Soviet Union fell apart. I think that one could, with equal validity, speak of a Nazi civilization, though this endured less than twenty years. In the case of very short-lived political entities like Nazism, it might be more accurate to speak in aspirational terms, i.e., in terms of what the nascent political entity hoped to achieve as a civilization.
In the case of both Soviet civilization and Nazi civilization, we have examples of failed civilizations due to failed central projects; when the central project of these respective civilizations failed, the civilizations failed. Thus if one defines a civilization in terms of a viable central project, the Soviet and Nazi experiments do not constitute civilizations, but rather failed attempts to found civilization de novo. However, this poses additional questions, such as whether a civilization founded on a central project that ultimately proves to be non-viable, but it takes hundreds of years for the civilization to well and truly fail, is a civilization. Should we deny that such failed civilizations constituted civilizations? I think there is a certain bias toward longevity that would make us hesitate to deny a long-lived failed civilization to be a civilization. So should we deny that short-lived failed civilizations are civilizations?
In my presentation “What kind of civilizations build starships?” (at the 2015 Starship Congress) I defined civilizations in terms of economic infrastructure and intellectual superstructure: where we find both, we have a civilization. I would now amend this, and add that a civilization is an economic infrastructure and an intellectual superstructure joined by a central project. This definition of civilization does not take longevity into account, so it can equally well apply to short-lived or long-lived civilizations.
The Eurozone has all the elements of civilization as I define it. There is an economic infrastructure, which might be identified with Rhine Capitalism; there is an intellectual superstructure, as embodied in the legal and political institutions of the EU, as well as the older ideas of European civilization and western civilization that transcend the specific context of the Eurozone; and there is a central project, the idea of Europe itself, transformed into a political idea.
Superficially, Eurozone civilization would seem to be a highly stable and viable enterprise, as many of the economic institutions and intellectual institutions are mutually supporting. For example, the free movement of populations, now being tested as a central pillar of European integration, is both an economic doctrine and a doctrine of personal liberty. However, despite these apparent virtues of the Eurozone, the project seems doomed to failure in its current incarnation, which, of course, does not mean that the Europeans cannot try again. There have been many movements to unify and integrate Europe over its long history, and we can expect that, if the current template for unification and integration fails, there will be future attempts.
A final thought: Europe has long been unified and integrated as a cultural and intellectual entity, and even as an economic entity. In other words, the unity of Europe is the same as the unity of our planetary civilization: unity in all relevant senses expect political and legal unification. But this legal and political unity has become a kind of fetish, so that we seem to be unable to recognize planetary civilization for what it is simply because we lack a planetary political order (cf. Origins of Globalization). In the same way, Europe has made a fetish of legal and political unification, and this has obscured the extent to which Europe is already one, single European civilization. The transformation of the idea of Europe into a political project may be the essential problem with the Eurozone. The motivation of this project — to prevent any future conflicts on the scale of the world wars of the twentieth century — primarily addresses the Franco-German rivalry that has characterized Europe since the death of Charlemagne. In so far as Britain has always been the “offshore balancer” to this continental rivalry, it is no surprise that Britain is the first powerful nation-state to seriously pose the question of its exit from the EU.

Recently in The Biological Conception of Civilization I defined civilization as a tightly coupled cohort of coevolving species. In proposing this definition, I openly acknowledged its limitations. This biological conception of civilization defines a biocentric civilization, and if civilization continues in its technological development, it may eventually pass from being a biocentric civilization, dependent upon intelligent organic species originating on planetary surfaces, to being a technocentric civilization, no longer dependent in this sense.
Even given these limitations of the biological conception of civilization, we need not abandon a biological framework entirely to converge upon a yet more comprehensive conception of civilization, beyond the biocentric, but still roughly characterized by conditions that we have learned from our tenure on Earth. Being ourselves an intelligent organic species existing on the surface of a planet, biological modes of thought can be made especially effective for minds such as ours, and it is in our cognitive interest to cultivate a mode of thought for which we are specially adapted.
Let us, then, go a little beyond a strictly biological conception of civilization and formulate an ecological conception of civilization. To make this conception immediately explicit, here is a first formulation…
The Ecological Conception of Civilization:
Civilization is niche construction by an intelligent species.
This formulation of the ecological conception of civilization could be amended to read, “by an intelligent species or by several intelligent species,” in order to anticipate the possibility of intelligence-rich biospheres that give rise to civilizations constituted by multiple intelligent species.
What is niche construction? Here is a sketch of the idea from a book on niche construction:
“…organisms… interact with environments, take energy and resources from environments, make micro- and macrohabitat choices with respect to environments, construct artifacts, emit detritus and die in environments, and by doing all these things, modify at least some of the natural selection pressures present in their own, and in each other’s, local environments.”
Niche Construction: The Neglected Process in Evolution, F. John Odling-Smee, Kevin N. Laland, and Marcus W. Feldman, Monographs in Population Biology 37, Princeton University Press, 2003, p. 1
The authors go on to say:
“All living creatures, through their metabolism, their activities, and their choices, partly create and partly destroy their own niches, on scales ranging from the extremely local to the global.”
Human interaction with the terrestrial environment is an obvious example of taking energy and resources from the environment on a global scale, altering the selection pressures on our own evolution as a species by both creating and destroying a niche for ourselves. We are not the first terrestrial organisms to act upon the planet globally; when stromatolites (microbial mats composed of cyanobacteria) were the dominant life form on Earth, their photosynthetic processes ultimately produced the Great Oxygenation Event and catastrophically changed the biosphere. Had it not been for that global catastrophic change of the biosphere, oxygen-breathing organisms such as ourselves could not have evolved.
Though we are not the first terrestrial organism to shape the biosphere entire, we are the first intelligent terrestrial agents to shape the biosphere, and it has been the application of human intelligence to the problem of human survival that has resulted in human beings adapting their activity to every terrestrial biome and so eventually constructing civilization. At the stage of the initial emergence of civilization, the biological and ecological conceptions of civilizations coincide, as niche construction takes the form of engineering a coevolving cohort of species beneficial to the intelligent agent intervening in the biosphere. In later stages in the development of civilization, the ecological conception is shown to be more comprehensive than the biological conception of civilization, and subsumes the biological conception of civilization.
Not any cohort of coevolving species constitutes a civilization. Pollinating insects (bees) and flowers are involved in what might be called a tightly-coupled cohort of coevolving species, but we could not call bees and flowers together a civilization. Perhaps on other worlds the distinction between what we call civilization and coevolution in the natural world would not be so evident, and we could not as confidently make the distinction. For us, however, this distinction seems obvious. Why? At least one difference between civilization and naturally occurring coevolution is that the tightly-coupled cohort of coevolving species that we call civilization has been purposefully engineered for the benefit of the intelligent species that has demonstrated its agency through this engineering of a niche for itself. Moreover, the engineered niche is entirely dependent upon ongoing intervention to maintain this engineered niche. In the absence of civilization, the tightly-coupled cohort(s) of coveolving species would unravel, while naturally occurring instances of coevolution would continue unchanged, i.e., they would continue to coevolve. (I leave it as an exercise to the reader to compare this observation to Schrödinger’s definition of life in thermodynamic terms.)
The necessary role of an intelligent agent in maintaining a coevolutionary cohort of species points beyond the biological conception of civilization to the ecological conception of civilization, which in term points beyond civilizations constructed by biological agents to the possibility of niches constructed by any intelligent agent whatsoever. This makes the ecological conception of civilization more comprehensive than the biological conception of civilization, as the intelligent agents involved in niche construction need not be biological beings. However, biological beings are likely to be the intelligent agents with which civilization begins.
In the kind of universe we inhabit, during the Stelliferous Era biology represents the first possible emergence of intelligent agency, hence the first possibility of intelligent niche construction. (I could hedge a bit on this and instead assert that biological agents are the first likely emergence of intelligent agents, as Abraham Loeb has posited the possibility of life in the very early universe — cf. “The Habitable Epoch of the Early Universe” — but I consider this scenario to be unlikely, and the possibility of such life yielding civilization even less likely.) This biocentric possibility of intelligent niche construction can later be supplemented or replaced by later forms of emergent complexity consistent with intelligent agency and capable of niche construction (which latter could involve either building on existing forms of intelligent niche construction or innovating new forms of intelligent niche construction transcending what we today understand as civilization).
The biological conception of civilization — an engineered coevolving cohort of species — constitutes one possible form of niche construction. That is to say, in managing an ecosystem so that it produces a disproportionate number of the plants and animals consumed as food or other products for the use of the directing intelligent agent (human beings in our case), human beings have attained the first possible stage of intelligent niche construction, which is essentially a delineation of biocentric civilization, but the ecological conception of civilization can be adapted to the understanding of non-biocentric civilizations, as, for example, in the case the technocentric civilizations. The various kinds of civilization that we have seen on Earth — including but not limited to agrarian-ecclesiastical civilization and industrial-technological civilization — represent distinct forms of intelligent niche construction, and therefore all fall within the ecological conception of civilization. Civilizations constructed by post-biological agents in the form of technological beings may build upon these constructed niches or construct niches more distinctly adapted to post-biological agents (which may be technological agents).
The ecological conception of civilization lends itself to technocentric extrapolation in so far as the ecological recognition of the biology of planetary endemism being dependent on solar flux is readily adapted to conceptions of civilization that have emerged from the work of Dyson and Kardashev. Dyson famously imagined stars so surrounded by the productions of a technological civilization that only the waste heat of these civilizations would be visible to us in the infrared spectrum, and Kardashev equally famously translated this idea into a formalism representing civilization types in terms of total energy resources commanded by a civilization. Even these distant extrapolations of the possibility of our technological civilization are still recognizably dependent upon stellar flux, no less than the biomass of our terrestrial environment is dependent upon solar flux, as stellar flux represents the primary source of readily available energy during the Stelliferous Era. In this way, even technocentric civilizations constructed by post-biological intelligent agents are continuous with the civilizations of planetary endemism emerging from the biology of planetary surfaces, and both are describable in ecological terms.
It could be said that the ecological conception of civilization presupposes the biological conception, because ecological systems supervene on biological systems (or, at least, ecological systems have supervened upon biological systems to date, but this is not a necessary relationship and may be superseded in the fullness of time), and an ecological perspective provides a conceptual framework placing civilization in the context of the natural world from which it emerged and upon which it depends, as well as placing any given civilization in the context of other civilizations. This latter function — providing a systematic framework for the interaction of civilizations — ultimately may be the most valuable aspect of the ecological conception of civilization, but one that can only be suggested at present. The ecological relationships familiar to us from the study of living organisms — mutualism (or symbiosis), commensalism, predation, and parasitism — may hold for civilizations also, but this kind of parallelism cannot be assumed. The ecological relationships among civilizations — i.e., among intelligent species that have engaged in niche construction — may well be more complex than the ecological relationships among organisms, but this is a matter for further study that I will not attempt to elaborate at present.
