“One salutary development in recent ethical theorizing is the widespread recognition that no short argument will serve to eliminate any of the major metaethical positions. Such theories have to weave together views in semantics, epistemology, moral psychology and metaphysics. The comprehensive, holistic character of much recent theorizing suggests the futility of fastening on just a single sort of argument to refute a developed version of realism or antirealism. No one any longer thinks that ethical naturalism can be undermined in a single stroke by the open question argument, or that appeal to the descriptive semantics of moral discourse is sufficient to refute noncognitivism.”

“Silence is one of the hardest arguments to refute".”

“There ought not be two histories, one of political and moral action and one of political and moral theorizing, because there were not two pasts, one populated only by actions, the other only by theories. Every action is the bearer and expression of more or less theory-laden beliefs and concepts; every piece of theorizing and every expression of belief is a politcal and moral action.”

“I have no interest in anything so frivolous as the bona fide religion or mankind's pathetic debate over whose version of the church is correct. Circular arguments over the semantics of faith hold no interest for me. Those are questions answered only through death!”

“some books against Deism fell into my hands ... it happened that they wrought an effect on me quite contrary to what was intended by them; for the arguments of the Deists, which were quote to be refuted, appeared to me much stronger than the refutations; in short, I soon became a thorough Deist.”

“Ethics and I had crossed paths recently, and I’m not sure that I fell on the right side of the morality line.”
