On what do Religious Naturalists base their morality?
Reasonable people have a good idea of what is good and right behavior. Ethical excellence and moral decency are well known. There is no mystery to them. They are the consequences of the civilizing of humanity. As such, they are naturally derived by societies rather than handed out by revelation. Religious Naturalism advocates a consensus composite of human virtues that have evolved over the milenia many of which are manifest in the social structures of our primate cousins. We have attempted, on our Tenets page and our Ecology page, to list specific ethical principals that Religious Naturalists have a tendency to affirm. See them for more depth on this question.
