92:2.6

Religion has at one time or another sanctioned all sorts of contrary and inconsistent behavior, has at some time approved of practically all that is now regarded as immoral or sinful. Conscience, untaught by experience and unaided by reason, never has been, and never can be, a safe and unerring guide to human conduct. Conscience is not a divine voice speaking to the human soul. It is merely the sum total of the moral and ethical content of the mores of any current stage of existence; it simply represents the humanly conceived ideal of reaction in any given set of circumstances.
