    1. FollowingSimondon’s social theory [37] and our previous work [10 ], social systems are themselves individualsthat harbour in them preindividual forces of transformation. Therefore we do not see in the currentorganization of personhood, inasmuch as it seems unassailable, a final unchangeable state of affairs.

    1. https://www.scientificamerican.com/article/the-complicated-legacy-of-e-o-wilson/

      I can see why there's so much backlash on this piece.

      It could and should easily have been written without any reference at all to E. O. Wilson and been broadly interesting and true. However given the editorial headline "The Complicated Legacy of E. O. Wilson", the recency of his death, and the photo at the top, it becomes clickbait for something wholly other.

      There is only passing reference to Wilson and any of his work and no citations whatsoever about who he was or why his work was supposedly controversial. Instead the author leans in on the the idea of the biology being the problem instead of the application of biology to early anthropology which dramatically mis-read the biology and misapplied it for the past century and a half to bolster racist ideas and policies.

      The author indicates that we should be better with "citational practices when using or reporting on problematic work", but wholly forgets to apply it to her own writing in this very piece.

      I'm aware that the magazine editors are most likely the ones that chose the headline and the accompanying photo, but there's a failure here in both editorial and writing for this piece to have appeared in Scientific American in a way as to make it more of a hit piece on Wilson just days after his death. Worse, the backlash of the broadly unsupported criticism of Wilson totally washed out the attention that should have been placed on the meat of the actual argument in the final paragraphs.

      Editorial failed massively on all fronts here.

      This article seems to be a clear example of the following:

      Any time one uses the word "problematic" to describe cultural issues, it can't stand alone without some significant context building and clear arguments about exactly what was problematic and precisely why. Otherwise the exercise is a lot of handwaving and puffery that does neither side of an argument or its intended audiences any good.

    2. Second, the application of the scientific method matters: what works for ants and other nonhuman species is not always relevant for health and/or human outcomes. For example, the associations of Black people with poor health outcomes, economic disadvantage and reduced life expectancy can be explained by structural racism, yet Blackness or Black culture is frequently cited as the driver of those health disparities. Ant culture is hierarchal and matriarchal, based on human understandings of gender. And the descriptions and importance of ant societies existing as colonies is a component of Wilson’s work that should have been critiqued. Context matters.

      The author is going in two opposite directions here and neither match up. A massive swath of our medicine research is wholly based on translational genetics. (That is, our basic research on organisms like flies (drosophila), worms (C. elegans), zebrafish, mice, rats, primates, etc. is contingent on moving medicines applicable to simpler genetic models in these animals will also work for humans who share large amounts of genetic material as the result of evolutionary dynamics. Sure some of it may not be relevant for humans because of both genetic and epigenetic (environmental) factors, but generally we expect that more will than won't.

      This basic fact is wholly separate from the health disparities issue. While there are some (and few of these are generally scientists in my experience) who believe that culture is the driving factor, there is enough proof to show that structural racism is the driving factor in almost all cases. I'm unaware of any translational genetic work on ant culture into human culture in any of the scientific literature and she certainly doesn't cite any to provide any sort of evidence to the contrary. As a result, she isn't providing any context at all.

      Raw capitalism mimics the logic of cancer within our body politic.

      Folks who have been reading David Wengrow and David Graeber's The Dawn of Everything are sure to appreciate the sentiment here which pulls in the ideas of biology and evolution to expand on their account and makes it a much more big history sort of thesis.

    2. Speaking of such lessons, Wilson and John Gowdy write, “the invisible hand metaphor can be justified … for humans in addition to nonhuman species, [only] when certain conditions are met.”

      Which conditions? How broad are they?

    3. Unfortunately, the ideas most economists use have been too influenced by “methodological individualism,” rather than the more scientifically supported view of us as a super-social, super-cooperative, intensely interdependent species. Often, this economics-style individualism is of the Thomas Hobbes variety, which paints humans in “a state of nature,” waging a “war of all against all.”

      This statement in the framing of biology is quite similar to the framing in anthropology and archaeology that David Graeber and David Wengrow provide in The Dawn of Everything.

      Perhaps we should be saying (especially from a political perspective): Cooperation is King!

    4. Unregulated parts can kill their wholes. 

      This is true in so many domains and not just biology.
