http://www.secweb.org/index.aspx?action=viewBook&id=901"The fool hath said in his heart, 'There is no God.' They are corrupt, they have done abominable works, there is none that doeth good." Psalm 14's moral indictment against atheism is presented self-servingly, overbroadly, melodramatically, and without a single shred of logical or empirical support--in other words, exactly the way monotheists prefer to hear it.
But today, in stark and refreshing contrast, we have popular authors like Michael Shermer--psychologist, science historian, publisher of Skeptic magazine, and monthly columnist for Scientific American--who recognize that moral issues, like all others, must be subjected to rational scrutiny.
Drawing from history, anthropology, science, and common sense in the finest tradition of intellectual eclecticism, Shermer adeptly demonstrates that ethics originate from neither gods nor religion, but rather from the same source as humanity itself--evolution. Religion, in its time, was partially successful in identifying universal moral and immoral thoughts and behaviors, and it may have been the first social institution to canonize moral principles, but despite the allegations of monotheists, it was hardly responsible for their genesis.
We evolved as a social primate, according to Shermer, "with an ascending hierarchy of needs from self-survival of the individual (basic biological needs), to the extension of the individual through the family (the selfish gene), to a sense of bonding with the extended family (driven by kin selection
helping those most related to us), to the reciprocal altruism of the community (direct and obvious payback for good behaviors), to indirect altruism of society (doing good without direct payback), to species altruism and bioaltruism as awareness of our membership in the species and biosphere continue to develop" (20).
