Review Materialmac's History

Materialism is the idea that everything is either made only of matter or is ultimately dependent upon matter for its existence and nature. It is possible for a philosophy to be materialistic and still accord spirit a (secondary or dependent) place, but most forms of materialism tend to reject the existence of spirit or anything non-physical.

Thinking emancipation. Radicalities and Social Movements in a Polarised World

The last few years have been marked by major economic, social and political turbulences. They have been years full of hope, but also full of threats. Years when the range of the possible has expanded. Years when we have seen innumerable injustices within a growing polarisation. In the face of an unprecedented crisis of civilisation, political and social activism has flourished anew, in parallel with the renaissance of reactionary forces and movements.

Materialism, also called physicalism, in philosophy, the view that all facts (including facts about the human mind and will and the course of human history) are causally dependent upon physical processes, or even reducible to them.

The word materialism has been used in modern times to refer to a family of metaphysical theories (i.e., theories of the nature of reality) that can best be defined by saying that a theory tends to be called materialist if it is felt sufficiently to resemble a paradigmatic theory that will here be called mechanical materialism. This article covers the various types of materialism and the ways by which they are distinguished and traces the history of materialism from the Greeks and Romans to modern forms of materialism.

Types of materialist theory

Mechanical materialism is the theory that the world consists entirely of hard, massy material objects, which, though perhaps imperceptibly small, are otherwise like such things as stones. (A slight modification is to allow the void—or empty space—to exist also in its own right.) These objects interact in the sort of way that stones do: by impact and possibly also by gravitational attraction. The theory denies that immaterial or apparently immaterial things (such as minds) exist or else explains them away as being material things or motions of material things.

Types distinguished by departures from the paradigm

In modern physics (if interpreted realistically), however, matter is conceived as made up of such things as electrons, protons, and mesons, which are very unlike the hard, massy, stonelike particles of mechanical materialism. In it the distinction between matter and energy has also broken down. It is therefore natural to extend the word materialist beyond the above paradigm case (of mechanical materialism) to cover anyone who bases his theory on whatever it is that physics asserts ultimately to exist. This sort may be called physicalistic materialism. Such a materialist allows the concept of material thing to be extended so as to include all of the elementary particles and other things that are postulated in fundamental physical theory—perhaps even continuous fields and points of space-time. Inasmuch as some cosmologists even try to define the elementary particles themselves in terms of the curvature of space-time, there is no reason why a philosophy based on such a geometricized cosmology should not be counted as materialist, provided that it does not give an independent existence to nonphysical things such as minds.

Still another departure from the paradigm is the theory that holds that everything is composed of material particles (or physical entities generally) but also holds that there are special laws applying to complexes of physical entities, such as living cells or brains, that are not reducible to the laws that apply to the fundamental physical entities. (To avoid inconsistency, such a theory may have to allow that the ordinary laws of physics do not wholly apply within such complex entities.) Such a theory, which could be called “emergent materialism,” can shade off, however, into theories that one would not wish to call materialist, such as hylozoism, which ascribes vital characteristics to all matter, and panpsychism, which attributes a mindlike character to all constituents of material things.

Another common relaxation of the paradigm is that which allows as compatible with materialism such a theory as epiphenomenalism, according to which sensations and thoughts do exist in addition to material processes but are nonetheless wholly dependent on material processes and without causal efficacy of their own. They are related to material things somewhat in the way that a thing’s shadow is related to the thing. A similar departure from the paradigm is a form of what might be called “double-aspect materialism,” according to which in inner experience one is acquainted with nonphysical properties of material processes, though these properties are not causally effective. A form of double-aspect theory in which these properties were allowed to be causally effective would be a species of emergent materialism.

Of course, more than one of these qualifications might be made at the same time. If no other qualifications are intended, it is convenient to use the word extreme and to speak, for example, of “extreme physicalist materialism”—which is probably the type most discussed among professional philosophers in English-speaking countries.

Type distinguished by its view of history

In the wider world, however, the word materialism may bring to mind dialectical materialism, which was the orthodox philosophy of communist countries. This is most importantly a theory of how changes arise in human history, though a general metaphysical theory lies in the background. Dialectical materialists contrast their view with what they call “vulgar” materialism; and it does, indeed, appear that their theory is not an extreme materialism, whether mechanical or physicalist. They seem to hold merely that mental processes are dependent on or have evolved from material ones. Though they might be akin to emergent materialists, it is hard to be sure; their assertion that something new emerges at higher levels of organization might refer only to such things as that a computer is different from a mere heap of its components. And if so, even an extreme physicalistic materialist could acquiesce in this view. The distinctive features of dialectical materialism would thus seem to lie as much in its being dialectical as in its being materialist. Its dialectical side may be epitomized in three laws: (1) that of the transformation of quantity into quality, (2) that of the interpenetration of opposites, and (3) that of the negation of the negation. Nondialectical philosophers find it hard, however, to interpret these laws in a way that does not make them into either platitudes or falsehoods.

Perhaps because of the historical determinismimplicit in dialectical materialism, and perhaps because of memories of the mechanical materialist theories of the 18th and 19th centuries, when physics was deterministic, it is popularly supposed that materialism and determinism must go together. This is not so. As indicated below, even some ancient materialists were indeterminists, and a modern physicalist materialism must be indeterministic because of the indeterminism that is built into modern physics. Modern physics does imply, however, that macroscopic bodies behave in a way that is effectively deterministic, and, because even a single neuron (nerve fibre) is a macroscopic object by quantum-mechanical standards, a physicalistic materialist may still regard the human brain as coming near to being a mechanism that behaves in a deterministic way.

Types distinguished by their account of mind

A rather different way of classifying materialist theories, which to some extent cuts across the classifications already made, emerges when the theories are divided according to the way in which a materialist accounts for minds. A central-state materialist identifies mental processes with processes in the brain. An analyticalbehaviourist, on the other hand, argues that, in talking about the mind, one is not talking about an actual entity, whether material (e.g., the brain) or immaterial (e.g., the soul); rather, one is somehow talking about the way in which people would behave in various circumstances. According to the analytical behaviourist, there is no more of a problem for the materialist in having to identify mind with something material than there is in identifying such an abstraction as the average plumber with some concrete entity. Analytical behaviourism differs from psychological behaviourism, which is merely a methodological program to base theories on behavioral evidence and to eschewintrospective reports. The analytical behaviourist usually has a theory of introspective reports according to which they are what are sometimes called “avowals”: roughly, he contends that to say “I have a pain” is to engage in a verbal surrogate for a wince. Epistemic materialism is a theory that can be developed either in the direction of central-state materialism or in that of analytical behaviourism and that rests on the contention that the only statements that are intersubjectively testable are either observation reports about macroscopic physical objects or statements that imply such observation reports (or are otherwise logically related to them).

Before leaving this survey of the family of materialistic theories, a quite different sense of the word materialism should be noted in which it denotes not a metaphysical theory but an ethical attitude. A person is a materialist in this sense if he is interested mainly in sensuous pleasures and bodily comforts and hence in the material possessions that bring these about. A person might be a materialist in this ethical and pejorative sense without being a metaphysical materialist, and conversely. An extreme physicalistic materialist, for example, might prefer a Beethoven recording to a comfortable mattress for his bed; and a person who believes in immaterial spirits might opt for the mattress.
