In Defense of Ethical Naturalism
The supernaturalist imagines that he possesses those absolutes which allows for genuine categorical imperatives. But these ‘absolutes’ ultimately turn out to be very human in origin, based (as they are for naturalists) on experience, conditioning, and specific theological interpretations by humans of codes attributed to supernatural authority, but which can be traced to some human or group of humans. Ultimately, the ‘absolutes’ of the religious authoritarian are in the same category with the ‘absolutes’ of any human-based morality.
