Two minds of @JeffSchweitzer
Schweitzer calls the gap between Christianity and science an "unbridgeable gulf", yet his theorizing of primeval times subverts his own opinion:
"Traits that we view as moral are deeply embedded in the human psyche. Honesty, fidelity, trustworthiness, kindness to others, and reciprocity are primeval characteristics that helped our ancestors survive. In a world of dangerous predators, early man could thrive only in cooperative groups. Good behavior strengthened the tribal bonds that were essential to survival. What we now call morality is really a suite of behaviors favored by natural selection in an animal weak alone but strong in numbers. Morality is a biological necessity and a consequence of human development, not a gift from God." (from Two Americas: Rationalists and Arationalists)
How convenient for Schweitzer to deploy his criticism of theists to dovetail his own faith in the undocumented human evolution of morality! Nowhere in his argument were the evidence and arguments of the best from the other side (say, Michael Behe's irreducible complexity) reasoned against or even mentioned. If this is all his article amounts to—a gross double standard in his own reasoning—at least I now know not to take Jeff Schweitzer's layman's ramblings seriously.
