There is ongoing debate about morality, its contents, and limits both within and outside of philosophy. Moral nihilism represents a fundamental negation of morality: morality is simply an illusion, nothing is ever right or wrong, just or unjust, good or bad. This volume discusses the views of such diverse authors as Nietzsche, Kierkegaard, Marx and Engels, the Marquis de Sade, and the ancient sophists.
