materialism (redirected from Secular materialism)

materialism, in philosophy, a widely held system of thought that explains the nature of the world as entirely dependent on matter, the fundamental and final reality beyond which nothing need be sought. Certain periods in history, usually those associated with scientific advance, are marked by strong materialistic tendencies. The doctrine was formulated as early as the 4th cent. B.C. by Democritus, in whose system of atomism all phenomena are explained by atoms and their motions in space. Other early Greek teaching, such as that of Epicurus and Stoicism, also conceived of reality as material in its nature. The theory was later renewed in the 17th cent. by Pierre Gassendi and Thomas Hobbes, who believed that the sphere of consciousness essentially belongs to the corporeal world, or the senses. The investigations of John Locke were adapted to materialist positions by David Hartley and Joseph Priestley. They were a part of the materialist development of the 18th cent., strongly manifested in France, where the most extreme thought was that of Julien de La Mettrie. The culminating expression of materialist thought in this period was the Système de la nature (1770), for which Baron d'Holbach is considered chiefly responsible. A reaction against materialism was felt in the later years of the 18th cent., but the middle of the 19th cent. brought a new movement, largely psychological in interpretation. Two of the modern developments of materialism are dialectical materialism and physicalism, a position formulated by some members of the Logical Positivist movement. Closely related to materialism in origin are naturalism and sensualism.

materialism

In metaphysics, the doctrine that all of reality is essentially of the nature of matter. In the philosophy of mind, one form of materialism, sometimes called central-state materialism, asserts that states of the mind are identical to states of the human brain. In order to account for the possible existence of mental states in creatures that do not share the human nervous system (e.g., octopuses and Martians), proponents of functionalism identified particular mental states with the functional or causal roles those states play with respect to other physical and mental states of the organism; this allows for the “multiple realizability” of the same mental state in different physical states. (Strictly speaking, functionalism is compatible with both materialism and non-materialism, though most functionalists are materialists.) As a form of materialism, functionalism is “nonreductive,” because it holds that mental states cannot be completely explained in terms that refer only to what is physical. Though not identical with physical states, mental states are said to “supervene” on them, in the sense that there can be no change in the former without some change in the latter. “Eliminative” materialism rejects any aspect of the mental that cannot be explained wholly in physical terms; in particular, it denies the existence of the familiar categories of mental state presupposed in folk psychology. See also identity theory; mind-body problem.
