Every man must decide whether he will walk in the light of creative altruism or in the darkness of destructive selfishness. Martin Luther King, Jr.
Morality binds people into groups. It gives us tribalism, it gives us genocide, war, and politics. But it also gives us heroism, altruism, and sainthood. Jonathan Haidt
If any civilization is to survive, it is the morality of altruism that men have to reject. Ayn Rand
Good character consists of recognizing the selfishness that inheres in each of us and trying to balance it against the altruism to which we should all aspire. It is a difficult balance to strike, but no definition of goodness can be complete without it. Alan Dershowitz
Commerce, trade and exchange make other people more valuable alive than dead, and mean that people try to anticipate what the other guy needs and wants. It engages the mechanisms of reciprocal altruism, as the evolutionary biologists call it, as opposed to raw dominance. Steven Pinker
