Steve stated: “As an atheist, Dr. Eco would decline the notion that incest taboos were divinely inspired, but he can offer no reasonable alternative to the sudden necessity for Jewish culture to record what he would term an evolutionary taboo.”
Actually, Steve, it seems that Dr. Eco is not an atheist. He's most likely agnostic. According to his book Belief or Nonbelief? — which consists of an open letter exchange with Cardinal Carlo Maria Martini — the atheist is ”a type whose psychology eludes me, because, as Kant observed, I do not see how one can not believe in God, and hold that His existence can not be proved, and then firmly believe in the nonexistence of God, holding that this can be proved.”
While many may miss the nuances, I must insist that there’s a lot separating atheism and agnosticism.
