2014 IBHA Conference Day 3
9 August 2014
Day 3 of the 2014 IBHA conference began with panel 32 in room 201, “Complexity (2).” Three speakers were scheduled, but one canceled so that more time was available to the other two. This turned out to be quite fortunate. This panel was, without question, one of the best I have attended. It began with Ken Baskin on “Sister Disciplines: Bringing Big History and Complexity Theory Together,” and continued with Claudio Maccone with “Entropy as an Evolution Measure (Evo-SETI Theory).”
Ken Baskin, author of the forthcoming The Axial Ages of World History: Lessons for the 21st Century, said that big history and complexity theory are “post-Newtonian disciplines that complement each other.” His subsequent exposition made a real impression to this end. He used the now-familiar concepts of complexity — complex adaptive systems (CAS), non-linearity, and attractors, strange and otherwise — to give an exposition of big history periodization. He presented historical changes as being “thick” — that is to say, not as brief transitional periods, but as extended transitional periods that led to even longer-term states of relative stability. According to his periodization, the hunter-gatherer era was stable, and was followed by the disruption of the agricultural revolution; this eventually issued in a stable “pre-axial” age, which was in turn disrupted by the Axial Age. The Axial Age transition lasted for several hundred years but gave way to somewhat stable post-Axial societies, and this in turn has been disrupted by a second axial age. According to Baskin, we have been in this second axial transition since about 1500 and have not yet settled down into a new, stable social regime.
Claudio Maccone is an Italian SETI astronomer who has written a range of technical books, including Mathematical SETI: Statistics, Signal Processing, Space Missions and Deep Space Flight and Communications: Exploiting the Sun as a Gravitational Lens. His presentation was nothing less than phenomenal. My response is partly due to the fact that he addressed many of my interests. Before the IBHA conference a friend asked me what I would have talked about if I had given a presentation. I said that I would have talked about big history in relation to astrobiology, and specifically that I would like to point out the similarities between the emergent complexity schema of big history to the implicit levels of complexity in the Drake equation. This is exactly what Maccone did, and he did so brilliantly, with equations and data to back up his argument. Also, Maccone spoke like a professor giving a lecture, with an effortless mastery of his subject.
Maccone said that, for him, big history was simply an extension of the Drake equation — the Drake equation goes back some ten million years or so, and by adding some additional terms to the beginning of the Drake equation we can expand it to comprise the whole 13.7 billion years of cosmic history. I think that this was one of the best concise statements of big history that I heard at the entire conference, notwithstanding its deviation from most of the other definitions offered. The Drake equation is a theoretical framework that is limited only by the imagination of the researcher in revising its terms and expression. And Maccone has taken it much further yet.
Maccone has worked out a revision of the Drake equation that plugs probability distributions into the variables of the Drake equation (which he published as “The Statistical Drake Equation” in Acta Astronautica, 2010 doi:10.1016/
j.actaastro.2010.05.003). His work is the closest thing that I have seen to being a mathematical model of civilization. All I can say is: get all his books and papers and study them carefully. It will be worth the effort.
Big History and the Future
The next panel was the most difficult decision to make of the conference, because in one room were David Christian, Cynthia Brown, and others discussing “Meaning in Big History: A Naturalistic Perspective,” but I chose instead to go to panel 39 in room 301, “Big History and the Future,” which was concerned with futurism, or, as is now said, “future studies.”
The session started out with J. Daniel May reviewing past visions of the future by a discussion of twentieth century science fiction films, including Metropolis, Forbidden Planet, Lost in Space, Star Trek, and 2001. I have seen all these films and television programs, and, as was evident by the discussion following the talk, many others had as well, citing arcane details from the films in their comments.
Joseph Voros then presented “On the transition to ‘Threshold 9’: examining the implications of ‘sustainability’ for human civilization, using the lens of big history.” The present big history schematization of the past that is most common (but not universal, as evidenced by this conference) recognizes eight thresholds of emergent complexity. This immediately suggests the question of what the next threshold of emergent complexity will be, which would be the ninth threshold, thus making the “ninth threshold” a kind of cipher among big historians and a framework for discussing the future in the context of big history. Given that the current threshold of emergent complexity is fossil-fueled civilization (what I call industrial-technological civilization), and given that fossil fuels are finite, an obvious projection for the future concerns the nature of a post-fossil-fuel civilization.
Voros claimed that all scenarios for the future fall into four categories: 1) continuation, 2) collapse (which is also called “descent”), 3) disciplined society (presumably what Bostrom would call “flawed realization”), and 4) transformational society, in which the transformation might be technological or spiritual. Since Voros was focused on post-fossil-fuel civilization, his talk was throughout related to “peak oil” concerns, though at a much more sophisticated level. He noted the the debate over “peak oil” is almost irrelevant from a big history perspective, because whether oil runs out now or later doesn’t alter the fact that it will run out being a finite resource renewable only over a period of time much greater than the time horizon of civilization. With this energy focus, he proposed that one of the forms of a “disciplined society” that could come about would be that of an “energy disciplined society.” Of the transformational possibilities he outlined four scenarios: 1) energy bonanza, 2) spiritual awakening, 3) brain/mind upload, and 4) childhood’s end.
After Voros, Cadell Last of the Global Brain Institute presented “The Future of Big History: High Intelligence to Developmental Singularity.” He began by announcing his “heretical” view that cultural evolution can be predicted. His subsequent talk revealed additional heresies without further trigger warnings. Last spoke of a coming era of cultural evolution in which the unit of selection is the idea (I was happy that he used “idea” instead of “meme”), and that this future would largely be determined by “idea flows” — presumably analogous to the “energy flows” of Eric Chaisson that have played such a large role in this conference, as well as the gene flows of biological evolution. (“Idea flows” may be understood as a contemporary reformulation of “idea diffusion.”) This era of cultural evolution will differ from biological evolution in that the idea flows, unlike gene flow in biological evolution, is not individual (it is cultural) and is not blind (conscious agents can plan ahead).
Last gave a wonderfully intuitive presentation of his ideas, and though it was the sort of thing that futurists recognize as familiar, I suspect much of what he said would strike the average listener as something akin to moral horror. Last said that, in the present world, biological and linguistic codes are in competition with each other, and gave the example familiar to everyone of having to make the choice whether to invest time and effort into biological descendants or cultural descendants. Scarcity of our personal resources means that we are likely to focus on one or the other. Finally, biological evolution will cease and all energies will be poured into cultural evolution. At this time, we will be free from the “tyranny of biology,” which requires that we engage in non-voluntary activities.
Reconceptualizations of Big History
For the final sessions divided into separate rooms I attended panel 44, “Reconceptualizations of Big History.” I came to this session primarily to hear to Camelo Castillo speak on “Mind as a Major Transition in big History.” Castillo, the author of Origins of Mind: A History of Systems, critiqued previous periodizations of big history, noting that they conflate changes in structure and changes in function. He then went on to define major transitions as, “transitions from individuals to groups that utilize novel processes to maintain novel structures.” With this definition, he went back to the literature and produced a periodization of six major transitions in big history. Not yet finished, he hypothesized that by looking for mind in the brain we are looking in the wrong place. Since all early major transitions involved both structures and processes, and from individuals to groups, that we should be looking for mind in social groups of human beings. The brain, he allowed, was implicated in the development of human social life, but social life is not reducible to the brain, and mind should be sought in theories of social intelligence.
Castillo’s work is quite rigorous and he defends it well, but I asked myself why we should not have different kinds of transitions at different stages of history and development, especially given that the kind of entities involved in the transition may be fundamentally distinct. Just as new or distinctive orders of existence require new or distinctive metrics for their measurement, so too new or distinctive orders of existence may come into being or pass out of being according to a transition specific to that kind of existent.
Final Plenary Sessions
After the individual session were finished, there was a series of plenary sessions. There was a presentation of Chronozoom, Fred Spier presented “The Future of Big History,” and finally there was a panel discussion entirely devoted to questions and answers, with Walter Alvarez, Craig Benjamin, Cynthia Brown, David Christian, Fred Spier, and Joseph Voros fielding the questions.
After the intellectual intensity of the sessions, it was not a surprise that these plenary sessions came to be mostly about funding, outreach, teaching, and the practical infrastructure of scholarship.
And with that the conference was declared to be closed.
