Does this argument stop me feeling entirely morally responsible for what I do? It does not. Does it stop you feeling entirely morally responsible? I very much doubt it. Should it stop us? Well, it might not be a good thing if it did.

determinism, the theory that absolutely everything that happens is causally determined to happen exactly as it does by what has already gone before — right back to the beginning of the universe.

A would-be relativist about morality needs to decide whether his view grants the existence of some absolute moral facts, or whether it is to be a pure relativism, free of any commitment to absolutes.  The latter position, I have argued, is mere nihilism; whereas the former leads us straight out of relativism and back into the quest for the moral absolutes.

Most moral relativists say that moral right and wrong are to be relativized to a community’s “moral code.”
