 Traditional normative moral theories generally fall into three types. Teleological theories seek to identify some supreme end or best way of life, and reduce the right and the virtuous to the promotion of this good. Deontological theories seek to identify a supreme principle or laws of morality independent of the good, and subordinate the pursuit of the good to conformity with the moral law. Virtue theories take phenomena of approval and disapproval to be fundamental, and derive the right and the good from them. Dewey declined to offer substantive answers to the traditional questions posed by these theories, arguing that no fixed ends or moral rules could be adequate in a world of constant change and plural and conflicting values. In place of fixed goals and rules of action, Dewey offered his method of experimental inquiry, which he argued was shared between theoretical and practical reason (RP 174). He drew insight from traditional moral theories by recasting their substantive answers to traditional moral questions in methodological terms.
