Psychological Egoism and Ethical Egoism

Yeah, psychological egoism more or less corresponds with evolutionary psychology, as long as it's recognised to be very subtle, and certain considerations are taken into account (eg, how being a social animal affects what "selfless" is) it looks pretty convincing.I'd remove the "only" from the Ethical Egoism definition, put in always some self interest instead, and again the same re-evaluation of "self-interested" within context is needed.I don't think these are meant as theories of advice on how we should behave btw, just commentaries on aspects of how we do behave.

Hey again, I don't think you'll get much argument here, the Wiki definitions are too simplistic, I don't think anyone believes them.
If we look at a mother jumping in front of a train to save a child, then it's obviously not selfish. But if we look at the effects on, and within the society can we see any other reasonable choice?
(not to suggest the mother calculates it)
People with no altruism don't last very long in a social society, so altruism is a neccesity within our social structure, so how is it altruism?
Perhaps you should replace "strongest-desire" with "deepest" or "subconscious" desire?
