I am an atheist, so I tend to find belief to be equivalent to superstition and group-think. I generally admire the ethical thinking of some believers -- the compassion, the commitment to justice, the reverence for "creation" -- but I am insulted at the suggestion by some believers that atheists cannot be equally ethical because our ethical commitments are not anchored to any fixed basis in revelation, scripture, or the promise of eternal rewards/punishments. When I reflect on the subject, I realize that there are certain advantages to having a moral framework as one finds in his chosen/inherited religious tradition. Where can an atheist go to consider and adopt his own framework? Are there any recommended readings on this question?
