The Nature of the Good
Another major difference in the approach to ethical problems revolves around the question of absolute good as opposed to relative good. Throughout the history of philosophy thinkers have sought an absolute criterion of ethics. Frequently moral codes have been based on religious absolutes. Immanuel Kant, in his categorical imperative, attempted to establish an ethical criterion independent of theological considerations. Rationalists (Plato, Baruch Spinoza, Josiah Royce) founded their ethics on a metaphysics.
All varying methods of building an ethical system pose the question of the degree to which morality is authoritative (i.e., imposed by a power outside the individual). If the criterion of morality is the welfare of the state (G. W. Hegel), the state is supreme arbiter. If the authority is a religion, then that religion is the ethical teacher. Hedonism, which equates the good with pleasure in its various forms, finds its ethical criterion either in the good of the individual or the good of the group. An egoistic hedonism (Aristippus, Epicurus, Julien de La Mettrie, Thomas Hobbes) views the good of the individual as the ultimate consideration. A universalistic hedonism, such as utilitarianism (Jeremy Bentham, James Mill), finds the ethical criterion in the greatest good for the greatest number.
