The best approach to morality and ethics, in my opinion, is a thoughtful blend of philosophy and science. I do not see a legitimate role for religion itself, however, cultural traditions (many of which may be codified in religious belief) are a useful source of information about the human condition and the effect of specific moral behaviors. There may be wisdom in such traditions – but that is the beginning of moral thinking, not the conclusion. Religious traditions also come with a great deal of baggage derived from the beliefs and views of fairly primitive and unenlightened societies.
