Social evolution

Another stupid piece by DIsco, in which David Klinghofer tries to blame Darwin for eugenics, totally overlooking the fact that the mediate source is animal husbandry, which predates Darwin by several thousand years, and that the immediate source is genetics, not evolution. I think that we should immediately teach the doctrine of signatures (in which natal traits are formed by the parents looking at similar objects, like the "striped and speckled sheep" in Genesis, which were mated before peeled branches) rather than genetics, because of the bad consequences of people misusing that science…

I didn't know my dad all that well. He died when I was 11, after a long illness that saw him in hospital for nearly 5 years, and he didn't show much evidence that he liked me much. All we ever shared was a love of science fiction.
I'm a father myself, of two wonderful kids, but I feel deeply the lack of a relationship, as a kid or as an adult, with my father. I have tried to be to my kids the father I wanted, and in so doing, made many mistakes. The lack of role models, of experience of father-ness, left me trying to work it out for myself.
The other night, I saw a documentary on…

A recent report on the songs of the eponymous "great tit", a common forest bird famous for learning to peck the foil tops of milk bottles in the 1950s, shows that they independently acquire a deeper song when in urban environments than when in forest environments. As the writer at ScienceNOW tells it, in forests they sound like Barry White, and in cities like Michael Jackson.
Passerine songs are usually adapted to the acoustics of their usual environment. Birds in denser vegetation will, I am told, end their songs on a rising sharp note, because there is more absorption of sound than in an…

So, in an obvious case of Scibling Rivalry, Jason Rosenhouse has taken me to task about my comments on Dawkins and agnosticism. Indeed, I have been fisked. Obviously one can decide about whether God exists or not, and agnostics are just inadequate atheists...
Let's set the scene with some philosophical definitions. A scientific question is one that evidence can tell for or against. All else is a philosophical question, or as it is popularly known, navel gazing. What is at issue here is whether or not evidence can tell for or against the notion that God exists. Atheists (and theists) say…
evolvingthoughts | October 25, 2006There's a fair bit of to-and-fro going on with the Sciblings about Richard Dawkins' latest book The God Delusion, which, being at the edge of empire, I haven't yet seen. When I do, I will read it and comment, of course.
But I want to ask a general question - is religion in itself a malign influence on society? For example, any number of Islamic Imams, including the leader of Australia's Muslim community, think that women who don't dress "modestly" (which can mean anything from wearing a long sleeved top to the burka) are to blame for being raped.
And attacks on the moral influence of…
evolvingthoughts | October 2, 2006Repost from the old blog:
One of the problems in having a philosophy related blog is that ideas are hard things to generate on demand, so often you need someone to raise the problems for you to think about. Being naturally (and preternaturally!) lazy, I don't go out looking for problems (of a philosophical nature; the ordinary kind seem to find me like flies find rotting garbage). Hence, this blog is sporadic.
Well, I just tripped over an interesting question raised by Certain Doubts: can we reconcile the Platonic value of truth with an evolutionary view of epistemology? That is, if we think…

I'm reading Robert Carneiro's Evolution in Cultural Anthropology (Westview Press, 2003) right now, and it's a good introduction to the debate over cultural evolution in the social sciences from Spencer to the present day. But I have some criticisms.
Carneiro's view of cultural evolution is basically Spencer's - evolution means unilinear progress. He got this via his mentors Leslie White, Marshall Sahlins, and Elman Service. He criticises Boyd, Richerson and Rindos for being too "neo-Darwinian":
Rindos states that as raw material to work on, "Darwinian selectionism requires undirected,…

Repost from the old blog: This week I am an Eighth Day Agnostic, as recent reformers in my irreligion have decided that we also don't know what a week is. My sermon for today begins with a question: When did it become possible to be an atheist?
On Friday I attended an interesting PhD confirmation seminar on the Marquis de Sade. Apart from a nice dirty graphic used as the backdrop, rather distractingly, for the PowerPoint presentation, there was little or no actual sex or sadism. Mostly the discussion centred on what it was that de Sade intended to be doing with his libertine ways. The…

What happens when rational coherence is not assumed, in the development of creationist views?
No child is able to make their epistemic set maximally coherent, and so it is likely that they will acquire a number of mutually inconsistent epistemic values and principles. If your parent tells you to try and see if things work out on the one hand, and that you need not do anything but believe the pastor or Bible on the other, this does not register for most young children as a conflict.
Young learners are natively active explorers and experimenters to some degree, but this doesn't immediately…
evolvingthoughts | September 9, 2006Where two principles really do meet which cannot be reconciled with one another, then each man declares the other a fool and heretic. [Ludwig Wittgenstein, On Certainty, 611]
A question I have wondered about for a long time is this: why do people become creationists? I mean, nobody is born a creationist (or an evolutionist, or a Mayan cosmic-cyclist, etc.). These are views that one acquires as one learns and integrates into society. But we live, notionally, in a society in which science has learned more about the world in 300 years than in the prior million or so. So, why do people become…
evolvingthoughts | September 3, 2006The New York Review of Books has an interesting article by Ronald Dworkin entitled "3 Questions for America". The three questions are:
1. Should alternatives to evolution be taught in schools? Dworkin says yes, but only if they are actually scientific. Alternatives derived from and dictated by religious beliefs don't count. He recommends that we (that is, the USAians, but it applies in broader international contexts) need a Contemporary Politics course that discusses how these sorts of issues arise and for what political purposes.
2. The Pledge of Allegiance. Though this is not cast as a…
evolvingthoughts | June 25, 2006Here is a paper in the Canadian Journal of Zoology which documents learned hunting behaviour among Tursiops truncatus, the bottlenose dolphin, in Western Australia.
Specialization and development of beach hunting, a rare foraging behavior, by wild bottlenose dolphins (Tursiops sp.)
B. L. Sargeant, J. Mann, P. Berggren, and M. Krützen
Abstract: Foraging behaviors of bottlenose dolphins vary within and among populations, but few studies attempt to address the causes of individual variation in foraging behavior. We examined how ecological, social, and developmental factors relate to the use of…

I often wonder what goes through the minds of those who propose utopian political ideals that turn out to become the worst of all possible dystopias, like Leninism or Maoism, or for that matter the extreme laisse faire capitalist conservatism. For it appears to me that these systems would work just fine, if only they didn't involve any human beings. And that raises an interesting question in my mind, and I hope, yours too. What sorts of political systems are biologically feasible for human beings? As Aristotle said, Man is a Political Animal, but what sort of political animal?
Any…
