@JLNobody,
Perhaps a little of both, eh? Armchair theoritizing is mighty fun and proves for lively debates, but the only language I know how to speak is a practical one. Where I'm from, thinking in metaphysics will get your physical face kicked in. (I almost wish I were kidding.) Call me jaded, rating on a curve, whatever-- I am just thoroughly apposed to the idea of even a practical altruism. Altruism gets exploited far more often than it is reciprocated in the real world. Once you have garnered a reputation of inerrant good will, the vultures circle.
I would even like to argue that even WHEN altruism is beneficial, it is not so much the altruism that is rewarded, but the
appearance of it. So who can argue whether the most viable strategy would be the "true" altruist, or the one who maintains the better facade? The latter would seem to have the better of both worlds.
Altruism I would even go so far as to label
cowardice. Not "do unto thy neighbor," but "do unto they neighbor for fear of what he may do to you." Is that subtle distinction lost entirely?
