Here is some of an interview on the issues we are discussing by Dr. Paul Copan: (for the whole article click here)
Evolutionary ethics produce skepticism about a human’s ability to know truth, Copan said, adding that Charles Darwin said, “With me, the horrid doubt always arises whether the convictions of man’s mind which has been developed from the mind of the lower animals are of any value or are even trustworthy.”
Ethical foundations, then, are undermined by “an evolutionary process that is interested in fitness and survival but not true beliefs,” Copan said.Theism offers a more plausible context for affirming human dignity than naturalism that puts moral objectivity and rational thought in question.
Copan cited the 1948 United Nations Universal Declaration of Human Rights to show that humans have an intrinsic understanding of human rights, regardless of religious convictions. He quoted French philosopher Jacques Maritain, one of the document’s drafters, who said, “God and objective morality cannot be plausibly separated since God is the Creator of valuable, morally responsible human beings and is the very source of value.”Copan concluded by saying that a moral argument alone doesn’t prove the existence of the Christian God but can be supplemented with other arguments for God.“The moral argument points us to a supreme, personal, moral being who is worthy of worship and who made us with dignity and worth,” Copan said. “He is a being to whom we are accountable and who could reasonably be called God.”
