Materialism

Materialism developed, possibly independently, in several geographically separated regions of Eurasia during what Karl Jaspers termed the Axial Age (c. 800–200 BC).

In ancient Indian philosophy, materialism developed around 600 BC with the works of Ajita Kesakambali, Payasi, Kanada and the proponents of the Cārvāka school of philosophy. Kanada became one of the early proponents of atomism. The Nyaya–Vaisesika school (c. 600–100 BC) developed one of the earliest forms of atomism (although their proofs of God and their positing that consciousness was not material precludes labelling them as materialists). Buddhist atomism and the Jaina school continued the atomic tradition.

Ancient Greek atomists like Leucippus, Democritus and Epicurus prefigure later materialists. The Latin poem De Rerum Natura by Lucretius (99 – c. 55 BC) reflects the mechanistic philosophy of Democritus and Epicurus. According to this view, all that exists is matter and void, and all phenomena result from different motions and conglomerations of base material particles called "atoms" (literally: "indivisibles"). De Rerum Natura provides mechanistic explanations for phenomena such as erosion, evaporation, wind and sound. Famous principles like "nothing can touch body but body" first appeared in the works of Lucretius. Democritus and Epicurus, however, did not hold to a monist ontology since they held to the ontological separation of matter and space (i.e. space being "another kind" of being) indicating that the definition of "materialism" is wider than the given scope of this article.

Wang Chong (27 – c. 100 AD) was a Chinese thinker of the early Common Era said to be a materialist.[6]

Later Indian materialist Jayaraashi Bhatta (6th century) in his work Tattvopaplavasimha ("The upsetting of all principles") refuted the Nyaya Sutra epistemology. The materialistic Cārvāka philosophy appears to have died out some time after 1400; when Madhavacharya compiled Sarva-darśana-samgraha (a digest of all philosophies) in the 14th century, he had no Cārvāka/Lokāyata text to quote from or refer to.[7]

In early 12th-century al-Andalus, the Arabian philosopher, Ibn Tufail (a.k.a. Abubacer), wrote discussions on materialism in his philosophical novel, Hayy ibn Yaqdhan (Philosophus Autodidactus), while vaguely foreshadowing the idea of a historical materialism.[8]

Thomas Hobbes (1588–1679)[9] and Pierre Gassendi (1592–1665)[10] represented the materialist tradition in opposition to the attempts of René Descartes (1596–1650) to provide the natural sciences with dualist foundations. There followed the materialist and atheist abbé Jean Meslier (1664–1729) and the works of the French materialists: Julien Offray de La Mettrie, the German-French Baron d'Holbach (1723–1789), Denis Diderot (1713–1784) and other French Enlightenment thinkers. In England, John "Walking" Stewart (1747–1822) insisted on seeing matter as endowed with a moral dimension, which had a major impact on the philosophical poetry of William Wordsworth (1770–1850).

In late modern philosophy, German atheist anthropologist Ludwig Feuerbach would signal a new turn in materialism through his book The Essence of Christianity (1841), which presented a humanist account of religion as the outward projection of man's inward nature. Feuerbach's anthropological materialism[11] (a version of materialism which views materialist anthropology as the universal science) would later heavily influence Karl Marx,[12] who in the late 19th century elaborated the concept of historical materialism—the basis for what Marx and Friedrich Engels outlined as scientific socialism:

The materialist conception of history starts from the proposition that the production of the means to support human life and, next to production, the exchange of things produced, is the basis of all social structure; that in every society that has appeared in history, the manner in which wealth is distributed and society divided into classes or orders is dependent upon what is produced, how it is produced, and how the products are exchanged. From this point of view, the final causes of all social changes and political revolutions are to be sought, not in men's brains, not in men's better insights into eternal truth and justice, but in changes in the modes of production and exchange. They are to be sought, not in the philosophy, but in the economics of each particular epoch.

— Friedrich Engels, Socialism: Scientific and Utopian (1880)

Engels later developed a "materialist dialectic" philosophy of nature (Dialectics of Nature, 1883). Engels's worldview was given the title "dialectical materialism" by Georgi Plekhanov, the father of Russian Marxism.[13] In early 20th-century Russian philosophy, Vladimir Lenin further developed dialectical materialism in his book Materialism and Empirio-criticism (1909), which connected the political conceptions put forth by his opponents to their anti-materialist philosophies.

A more naturalist-oriented materialist school of thought that developed in the middle of the 19th century (also in Germany) was German materialism: members included Ludwig Büchner, Jacob Moleschott and Carl Vogt.[14][15]

Contemporary analytic philosophers (e.g. Daniel Dennett, Willard Van Orman Quine, Donald Davidson, and Jerry Fodor) operate within a broadly physicalist or scientific materialist framework, producing rival accounts of how best to accommodate the mind, including functionalism, anomalous monism, identity theory, and so on.[16]

Scientific materialism is often synonymous with, and has typically been described as being, a reductive materialism. In the early twenty-first century, Paul and Patricia Churchland advocated a radically contrasting position (at least, in regards to certain hypotheses); eliminativist materialism holds that some mental phenomena simply do not exist at all, and that talk of those mental phenomena reflects a totally spurious "folk psychology" and introspection illusion. An eliminative materialist might believe that a concept like "belief" simply has no basis in fact (e.g. the way folk science speaks of demon-caused illnesses). With reductive materialism being at one end of a continuum (our theories will reduce to facts) and eliminative materialism on the other (certain theories will need to be eliminated in light of new facts), revisionary materialism is somewhere in the middle.[16]

Contemporary continental philosopher Gilles Deleuze has attempted to rework and strengthen classical materialist ideas.[17] Contemporary theorists such as Manuel DeLanda, working with this reinvigorated materialism, have come to be classified as "new materialist" in persuasion.[18] New materialism has now become its own specialized subfield of knowledge, with courses being offered on the topic at major universities, as well as numerous conferences, edited collections and monographs devoted to it. Jane Bennett's book Vibrant Matter (2010) has been particularly instrumental in bringing theories of monist ontology and vitalism back into a critical theoretical fold dominated by poststructuralist theories of language and discourse.[19] Scholars such as Mel Y. Chen and Zakiyyah Iman Jackson, however, have critiqued this body of new materialist literature for its neglect in considering the materiality of race and gender in particular.[20][21] Métis scholar Zoe Todd and Mohawk (Bear Clan, Six Nations) and Anishinaabe scholar Vanessa Watts,[22] query the colonial orientation of the race for a "new" materialism.[23] Watts in particular describes the tendency to regard matter as a subject of feminist or philosophical care as a tendency that is too invested in the reanimation of a Eurocentric tradition of inquiry at the expense of an Indigenous ethic of responsibility.[24] While, other scholars, such as Helene Vosters, echo their concerns and have questioned whether there is anything particularly "new" about this so-called "new materialism", as Indigenous and other animist ontologies have attested to what might be called the "vibrancy of matter" for centuries.[25] Other scholars such as Thomas Nail have critiqued "vitalist" versions of new materialism for its depoliticizing "flat ontology" and for being ahistorical in nature.[26][27]

Quentin Meillassoux proposed speculative materialism, a post-Kantian return to David Hume which is also based on materialist ideas.[28]

Rudolf Peierls, a physicist who played a major role in the Manhattan Project, rejected materialism, saying, "The premise that you can describe in terms of physics the whole function of a human being [...] including knowledge and consciousness, is untenable. There is still something missing".[38]

Erwin Schrödinger said, "Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else".[39]

Werner Heisenberg, who came up with the uncertainty principle, wrote, "The ontology of materialism rested upon the illusion that the kind of existence, the direct 'actuality' of the world around us, can be extrapolated into the atomic range. This extrapolation, however, is impossible...Atoms are not things".[40]

Some 20th-century physicists (such as Eugene Wigner[41] and Henry Stapp)[42] and modern day physicists and science writers (such as Stephen Barr,[43] Paul Davies and John Gribbin) have argued that materialism is flawed due to certain recent scientific findings in physics, such as quantum mechanics and chaos theory. In 1991, Gribbin and Davies released their book The Matter Myth, the first chapter of which, "The Death of Materialism", contained the following passage:

Then came our Quantum theory, which totally transformed our image of matter. The old assumption that the microscopic world of atoms was simply a scaled-down version of the everyday world had to be abandoned. Newton's deterministic machine was replaced by a shadowy and paradoxical conjunction of waves and particles, governed by the laws of chance, rather than the rigid rules of causality. An extension of the quantum theory goes beyond even this; it paints a picture in which solid matter dissolves away, to be replaced by weird excitations and vibrations of invisible field energy. Quantum physics undermines materialism because it reveals that matter has far less "substance" than we might believe. But another development goes even further by demolishing Newton's image of matter as inert lumps. This development is the theory of chaos, which has recently gained widespread attention.

— Paul Davies and John Gribbin, The Matter Myth, Chapter 1

The objections of Davies and Gribbin are shared by proponents of digital physics who view information rather than matter to be fundamental. Famous physicist and proponent of digital physics John Archibald Wheeler wrote, "all matter and all things physical are information-theoretic in origin and this is a participatory universe".[44] Their objections were also shared by some founders of quantum theory, such as Max Planck, who wrote:

As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent Mind. This Mind is the matrix of all matter.

— Max Planck, Das Wesen der Materie, 1944

James Jeans concurred with Planck saying, "The Universe begins to look more like a great thought than like a great machine. Mind no longer appears to be an accidental intruder into the realm of matter".[45]

According to Constantin Gutberlet writing in Catholic Encyclopedia (1911), materialism, defined as "a philosophical system which regards matter as the only reality in the world [...] denies the existence of God and the soul".[46] In this view, materialism could be perceived incompatible with world religions that ascribe existence to immaterial objects.[47] Materialism could be conflated with atheism. However, Friedrich Lange wrote in 1892, "Diderot has not always in the Encyclopædia expressed his own individual opinion, but it is just as true that at its commencement he had not yet got as far as Atheism and Materialism".[48]

Most of Hinduism and transcendentalism regard all matter as an illusion called Maya, blinding humans from knowing the truth. Transcendental experiences like the perception of Brahman are considered to destroy the illusion.[49]

Joseph Smith, the founder of the Latter Day Saint movement, taught: "There is no such thing as immaterial matter. All spirit is matter, but it is more fine or pure, and can only be discerned by purer eyes; We cannot see it; but when our bodies are purified we shall see that it is all matter."[50] This spirit element is believed to always have existed and to be co-eternal with God.[51]

Mary Baker Eddy, the founder of the Christian Science movement, denied the existence of matter on the basis of the allness of Mind (which she regarded as a synonym for God).[52]

In the Critique of Pure Reason, Immanuel Kant argued against materialism in defending his transcendental idealism (as well as offering arguments against subjective idealism and mind–body dualism).[53][54] However, Kant with his refutation of idealism, argues that change and time require an enduring substrate.[55][56] Postmodern/poststructuralist thinkers also express a skepticism about any all-encompassing metaphysical scheme. Philosopher Mary Midgley argues that materialism is a self-refuting idea, at least in its eliminative materialist form.[57][58][59][60][61]

Arguments for idealism, such as those of Hegel and Berkeley, often take the form of an argument against materialism; indeed, the idealism of Berkeley was called immaterialism. Now, matter can be argued to be redundant, as in bundle theory, and mind-independent properties can, in turn, be reduced to subjective percepts. Berkeley presents an example of the latter by pointing out that it is impossible to gather direct evidence of matter, as there is no direct experience of matter; all that is experienced is perception, whether internal or external. As such, the existence of matter can only be assumed from the apparent (perceived) stability of perceptions; it finds absolutely no evidence in direct experience.

If matter and energy are seen as necessary to explain the physical world, but incapable of explaining mind, dualism results. Emergence, holism and process philosophy seek to ameliorate the perceived shortcomings of traditional (especially mechanistic) materialism without abandoning materialism entirely.

Some critics object to materialism as part of an overly skeptical, narrow or reductivist approach to theorizing, rather than to the ontological claim that matter is the only substance. Particle physicist and Anglican theologian John Polkinghorne objects to what he calls promissory materialism—claims that materialistic science will eventually succeed in explaining phenomena it has not so far been able to explain.[62] Polkinghorne prefers "dual-aspect monism" to materialism.[63]

Some scientific materialists have been criticized for failing to provide clear definitions for what constitutes matter, leaving the term "materialism" without any definite meaning. Noam Chomsky states that since the concept of matter may be affected by new scientific discoveries, as has happened in the past, scientific materialists are being dogmatic in assuming the opposite.[36]
