This is the last in a series of five posts on morality. They are aimed at countering the usual religious claims for a god-given morality with current scientific understanding of how the morality of our species arose. Also, they at tempt to justify a non-theist objective basis for much of the moral decisions we make. The first post (I: Religious confusion) discussed some of the problems religion has in its understanding of morality and the second (II: Objective morality) argues for a non-theist objective basis for morality. The third post (III: Moral intuition) discussed moral intuitions and the fourth (IV: Role of religion) the role of religion. This last post discusses the secular conscience.
I have been arguing for a non-theist understanding of human morality. We can accept moral codes, and an objective basis for moral truths, without resorting to a god hypothesis. Historically religion has served a purpose in codifying and teaching moral law – but it is not the origin of these laws. In a sense, religion is parasitic on secular morality. It claims an authority in the area that it doesn’t deserve. And religious apologists often complete this takeover by claiming that religion itself, or the supernatural beings they promote, are the source of human morality.
