New publications 25 Aug 201225 Aug 2012 I have added some under-review drafts of my papers to the PhilPapers archive: Essentialism in Biology. Essentialism in philosophy is the position that things, especially kinds of things, have essences, or sets of properties, that all members of the kind must have, and the combination of which only members of the kind do, in fact, have. It is usually thought to derive from classical Greek philosophy and in particular from Aristotle’s notion of “what it is to be” something. In biology, it has been claimed that pre-evolutionary views of living kinds, or as they are sometimes called, “natural kinds”, are essentialist. This static view of living things presumes that no transition is possible in time or form between kinds, and that variation is regarded as accidental or inessential noise rather than important information about taxa. In contrast it is held that Darwinian, and post-Darwinian, biology relies upon variation as important and inevitable properties of taxa, and that taxa are not, therefore, kinds but historical individuals. Recent attempts have been made to undercut this account, and to reinstitute essentialism in biological kind terms. Others argue that essentialism has not ever been a historical reality in biology and its predecessors. In this chapter, I shall outline the many meanings of the notion of essentialism in psychology and social science as well as science, and discuss pro- and anti-essentialist views, and some recent historical revisionism. It turns out that nobody was essentialist to speak of in the sense that is antievolutionary in biology, and that much confusion rests on treating the one word, “essence” as meaning a single notion when in fact there are many. I shall also discuss the philosophical implications of essentialism, and what that means one way or the other for evolutionary biology. Teaching about evolution relies upon narratives of change in the ways the living world is conceived by biologists. This is a core narrative issue. Gods Above: Naturalizing Religion in Terms of Our Shared Ape Social Dominance Behavior. To naturalize religion we must identify what religion is, and what aspects of it we are trying to explain. In this paper religious social institutional behavior is the explanatory target, and an explanatory hypothesis based on shared primate social dominance psychology is given. The argument is that various religious features, including the high status afforded the religious, and the high status afforded to deities, is an expression of this social dominance psychology in a context for which it did not evolve: high density populations made possible by agriculture. Naturally these are unreviewed, unedited and probably under-thought. Cognition Evolution Metaphysics Natural Classification Race and politics Religion Social evolution Systematics
Evolution Cultural evolution essay 6 Jul 2010 At On The Human there’s an essay by Bill Benzon, a friend and colleague of mine, on cultural evolution: “Cultural Evolution: A Vehicle For Cooperative Interaction Between The Sciences And The Humanities”. It’s open to informed and moderated comments in what they cutely call a Sympoze. One of the comments… Read More
Evolution The first phylogeny 30 Sep 202030 Sep 2020 The only diagram in the Origin is famously the hypothetical series of species forming a tree structure, but it isn’t an actual classification based on his principles. I have previously noted the rise of cladograms towards the end of the 19th century, but in a talk by Ian Hesketh, I was… Read More
Evolution The two Wilsons on sociobiology 18 Nov 200718 Sep 2017 It’s not often I get to comment on as-yet-unpublished work, but I have been sent a copy of a forthcoming essay by David Sloan Wilson and Edward O. Wilson, two giants of the theoretical evolutionary field, defending and redefining the nature of sociobiology (Wilson and Wilson 2007). As I have… Read More
