Can man live ethically and morally without the guidance of religion?
Goodness and justice can be discerned and practiced without the guidance of religion -- the old children's Christmas song is correct, "Be good -- for goodness sake." While the same song posits desire for Santa's gifts and rewards) as motivation for being good, the rewards are in a good and just -- and safe -- society. I want to preface a bit that now there is no moral or ethical system that has not been influenced in some way by a religion because a lot of our ethics, like it or not, originate in religion, even if it's just a respect for life. Man Is An Animal Just Like Any Other, He Is Just A Brilliant Ape Animals, though less intelligent than humans, are, basically, the same as them.
