Kant and Rawls do not deny they are advancing certain moral ideals. Their quarrel is with theories of justice that derive rights from some conception of the good. Utilitarianism is one such theory. It takes the good to consist in maximizing pleasure or welfare, and asks what system of rights is likely to achieve it. Aristotle offers a very different theory of the good. It is not about maximizing pleasure but about realizing our nature and developing our distinctly human capacities. Aristotle’s reasoning is teleological in that he reasons from a certain conception of the human good.
