Thinkquotes of the day: Altruism simply promotes your own genes?

A boffo evolutionary biologist accounts for altruism:
The mathematical models of population genetics suggest the following rule in the evolutionary origin of altruism If the reduction of survival and reproduction of individuals due to genes for altruism is more than offset by the increased probability of survival of the group due to the altruism, the altruism will rise in frequency throughout the entire population of competing groups. Put as concisely as possible: The individual pays, his genes and tribe gain, altruism spreads. - (E. O. Wilson, Consilience: The Unity of Knowledge, p. 282 (Random House: Vintage Books, 1998)


From the movie, Gandhi, Gandhi's advice to a fellow Hindu who had killed a Muslim who had killed his son, and now feared he was
going to hell:
Gandhi sees the man's unbearable grief and remorse. He gently tells him, "I know a way out of hell. Find a child, a child whose mother and father have been killed - a little boy - and raise him as your own. Only be sure that he is a Muslim..."
The man's expression changes to one of hope. He suddenly sees a way in can undo what he has done and effect a restitution. He can replace his own son and provide a Muslim orphan with a home and parents. It is a perfect solution.

The man baulks, however, when Gandhi insists he raise the boy as a Muslim, but notice we don't hear anything here about genes or even tribes in the genetic sense. It all turns on ideas.

And then of course, in the immortal words of a Jewish itinerant preacher, "A man was going down from Jerusalem to Jericho when he fell into the hands of robbers ... " Read the whole thing and ask yourself where altruism means promoting your own tribe?

The major problem with evolutionary biology accounts of altruism is that most people don't even consider the behavior that merely promotes one's own family altruism. Taken to extremes - as it must be, to work the way Wilson needs it to - it is called amoral familism and is widely regarded as a key source of underdevelopment in backward societies.

Thinkquote of the day: Either religion offers true insight or evolutionary psychology explains it - no middle ground

Philosopher Kim Sterelny, reviewing Daniel Dennett's Breaking the Spell for American Scientist, writes on the impossibility of an explanation of religion according to "evolutionary psychology" that is not corrosive of religious faith,
... , secular theories of religion are corrosive. Religious commitment cannot both be the result of natural selection for (for example) enhanced social cohesion and be a response to something that is actually divine. A cohesion-and-cooperation model of religion just says that believers would believe, whether or not there was a divine world to which to respond. If a secular theory of the origin of religious belief is true, such belief is not contingent on the existence of traces of the divine in our world. So although a secular and evolutionary model of religion might be (in a strict sense) neutral on the existence of divine agency, it cannot be neutral on the rationality of religious conviction.

In other words, the universe really is either top down or bottom up. If it is top down, you may have had a revelation. If it is bottom up, you cannot have had a relevation, though - as an animal - you may be motivated to believe you did.

But, like all materialists, Sterelny turns out to have an unfalsifiable viewpoint of his own where materialism is concerned. I noted this in By Design or by Chance?, p. 196, where Sterelny was defending one of Richard Dawkins' just-so stories about Darwinian evolution:

Many have wondered why a creature that is on its way to becoming a stick insect would be more
likely to survive if it looked five percent like a stick rather than four percent like a stick. Surely a purely random process could not fool a predator by generating so small a difference? Dennett quotes philosopher Kim Sterelny in response:

"I do think this objection is something of a quibble because essentially I agree that natural selection is the only possible explanation of complex adaptation. So something like Dawkins’ stories have got to be right."

Essentially, Dennett is saying that we must accept the Darwinist explanation for the evolution of a stick insect not because it is an especially good explanation but because it upholds Darwin's theory. (Sterelny’s review of Dawkins’s The Blind Watchmaker was in the Australasian Journal of Philosophy (1988), vol. 66: 421–66.)

In my experience, materialists see nothing wrong with forcing others to pay for and study from publicly funded textbooks advancing their view - and no other - even when their view is sourced only by its own fanatical assertion. Indeed, dazed by the growing volume of complaints, they warn that objectins mean that the end of all things is at hand.

I have been appealing for years for a social scientist or anthropologist to study Darwinism, the creation story of materialism, as a cultural phenomenon. It cries out for that treatment. Besides, such a study would make a great trade book after the journal articles have been published; just the thing for an up-and-coming young academic.
