materialism
From New Latin materialismus, built on Late Latin materialis (“of matter, material, physical”), from Latin materia (“matter, stuff, timber, substance, subject”), itself probably from mater (“mother”) in the sense of ‘source material.’ The English noun “materialism” is attested from the 17th century, initially for a general emphasis on material things, and then more strictly as a metaphysical doctrine that only matter and its motions are real.
At a Glance
- Origin
- Latin via Early Modern English (root: Latin materia, materialis)
- Semantic Field
- Latin *materia* (matter, substance, wood, topic); *materialis* (material, physical); related English terms: matter, material, materiality, materialist, materialistic, corporeal, physical, natural, naturalism; contrasted with: spirit, spiritual, immaterial, ideal, idealism, dualism.
“Materialism” oscillates between a technical metaphysical thesis (all that exists is matter or is ultimately physical) and a moral-psychological attitude (attachment to wealth and possessions). In many languages one word must cover both senses, which can obscure whether a text is about ontology, ethics, or culture. Philosophically, it is also tricky to render in contexts where ‘matter’ is not a basic category (e.g., classical Chinese or some Indian traditions), or where contemporary physics undermines a naïve, solid-substance notion of matter. This raises the question whether ‘materialism’ should be translated as ‘physicalism,’ ‘naturalism,’ or left as a historical term with a narrower classical meaning, making precise equivalence difficult.
Before becoming a technical metaphysical term, words derived from *materia* and ‘material’ referred broadly to physical stuff, building timber, raw resources, or the subject matter of a discussion. In pre-philosophical moral discourse, ‘materialist’ attitudes could signify excessive concern with wealth and tangible goods rather than spiritual or moral values, an evaluative rather than ontological usage.
Philosophically, materialist ideas first crystallized in ancient cosmologies that posited fundamental stuff(s) as the basis of all things (e.g., Milesian monism, atomism). Early modern thinkers such as Hobbes, Gassendi, and La Mettrie reasserted a robust materialism by identifying reality with extended, mechanically interacting bodies. From the 18th century onward, ‘materialism’ became a contested label in debates over the soul, free will, and religion, crystallizing in the 19th century with scientific materialism’s claim that physiology and chemistry explain life and mind, and with Marx and Engels’ historical materialism extending the principle to society and history.
In contemporary usage, ‘materialism’ has three main strands: (1) a metaphysical thesis, often overlapping with ‘physicalism,’ that everything is ultimately physical; (2) a socio-economic or cultural attitude prioritizing material wealth, consumption, and measurable outcomes; and (3) a family of Marxist theories (historical and dialectical materialism) that explain social change through material productive relations. Academic philosophers now often prefer ‘physicalism’ for precise metaphysical claims, reserving ‘materialism’ either for historical doctrines or for wider, sometimes polemical, uses in political, cultural, and religious discourse.
1. Introduction
Materialism, in its philosophical sense, is the family of views that regard reality as fundamentally material or physical. It holds that whatever exists is either material in nature or depends in some robust way on material processes. Across its history, the term has also acquired moral, social, and political meanings, ranging from a focus on wealth and consumption to theories that prioritize material conditions in explaining history and society.
Philosophically, materialism typically contrasts with idealism, which makes mind or spirit primary, and with dualism, which posits both mental and physical substances or properties. Materialist positions have tended to arise where thinkers sought to explain the world—including life, mind, and society—without invoking immaterial substances, divine interventions, or irreducible mental entities.
Historically, materialist doctrines have taken different forms:
- Ancient atomism explained the cosmos and soul through the motions of indivisible atoms in the void.
- Early modern mechanical materialism interpreted bodies, minds, and even political order as systems of interacting particles governed by mechanical laws.
- Scientific materialism in the 18th and 19th centuries aligned itself with physiology, chemistry, and physics to claim that science could account for life and consciousness.
- Marxist materialisms (historical and dialectical) extended materialist explanation to social structures and historical change.
- Contemporary analytic physicalism generalizes materialism in light of modern physics, treating all entities as physical or physically realized.
Beyond metaphysics, “materialism” names ethical and cultural orientations that emphasize material prosperity, consumption, or this-worldly concerns, as well as theoretical approaches in the social sciences that highlight economic and infrastructural factors.
This entry surveys the linguistic origins of the term, its major historical forms, its role in contemporary philosophy and social theory, its relations to rival doctrines, and the criticisms it has attracted, while noting how changes in scientific conceptions of matter have reshaped what “materialism” can mean.
2. Etymology and Linguistic Origins
The word materialism entered European philosophical vocabulary in the early modern period, but its roots lie in Latin. Materia originally meant “wood” or “timber” and, by extension, “stuff,” “substance,” or the “subject” of a discussion. The adjective materialis (“of matter,” “material”) later provided the basis for technical terms referring to the physical realm.
A schematic overview:
| Term | Language | Basic meaning | Relation to “materialism” |
|---|---|---|---|
| materia | Classical Latin | wood, raw stuff, substance | root for “matter,” “material” |
| materialis | Late Latin | of matter, bodily, physical | source of “material,” “materialist” |
| materialismus | New Latin | doctrine centered on matter | learned coinage for philosophical use |
| materialism | Early Modern English | concern with material things; later, metaphysical doctrine | modern English term |
In 17th‑century English and French, materialism and matérialisme were initially used loosely to criticize an excessive preoccupation with bodily or worldly concerns. Only gradually did they acquire a more precise metaphysical sense: that only material things exist, or that all phenomena can be explained by matter and its motions. In German, Materialismus became firmly associated with naturalistic and often anti-theological positions, especially in 19th‑century debates.
Linguists note that the semantic field around materia intersects with both physical “stuff” and the “subject matter” of discourse. This duality sometimes surfaces in philosophical usage, where “material” can mean both “corporeal” and “relevant or substantive” (as in “material evidence”).
The etymological link between materia and mater (“mother”) has encouraged symbolic interpretations of matter as a generative source, though philologists disagree on how direct this derivation is. In any case, the historical shift from concrete “timber” to abstract “matter” parallels the conceptual transition from everyday talk of physical things to systematic metaphysical claims about the basic constituents of reality.
These linguistic developments set the stage for later philosophical crystallizations of materialism in antiquity, early modernity, and contemporary thought.
3. Pre-Philosophical and Everyday Usage
Before “materialism” became a technical philosophical term, related words functioned in ordinary language to mark attitudes toward worldly goods and physical life. In many European languages, the everyday sense of materialism centers on attachment to wealth, possessions, and bodily comfort, often with an implicit moral judgment.
In common usage, several overlapping meanings can be distinguished:
| Everyday sense | Typical connotation | Example usage |
|---|---|---|
| Consumerist/materialistic lifestyle | pejorative; excessive concern with money and goods | “The culture is becoming increasingly materialistic.” |
| This‑worldliness vs. spirituality | contrastive; focus on earthly rather than spiritual concerns | “He abandoned spiritual pursuits for a materialist outlook.” |
| Practical, concrete focus | sometimes neutral or positive | “We must address the material conditions of the poor.” |
Religious and moral discourse, especially within Christian, Islamic, and Buddhist traditions, has often used “materialist” (or equivalents) to criticize people or societies seen as prioritizing bodily pleasures, economic gain, or worldly success over spiritual growth or moral duty. In such contexts, “materialism” is less a metaphysical thesis than a characterization of values.
In social and political rhetoric, “materialism” can appear in more neutral or analytical ways. For instance, sociologists and activists may talk about material conditions—housing, nutrition, employment, infrastructure—without implying any denial of spiritual realities. Here, “material” simply designates tangible resources and economic structures.
The coexistence of these senses sometimes produces ambiguities. A thinker may be labeled “materialist” because of their economic determinism, their metaphysical denial of immaterial souls, or their personal focus on wealth, and in some debates these dimensions are conflated. Critics of philosophical materialism have at times exploited the negative moral associations of everyday “materialism” to cast doubt on the doctrine, while defenders have insisted on separating ontological claims about what exists from evaluative claims about what should be valued.
This ambiguity continues in contemporary media and public discourse, where “materialism” is frequently discussed in the context of consumer culture, secularization, and changing attitudes toward religion, sometimes independently of any explicit philosophical commitments about the nature of reality.
4. Ancient Materialist Traditions
Ancient materialist traditions emerged in several cultures, though the best-documented and most influential for later Western philosophy are Greek. These traditions typically posited that all things, including soul and gods (if admitted), consist of some kind of basic material stuff or elements governed by natural laws.
Greek Atomism: Leucippus, Democritus, Epicurus, Lucretius
Classical atomism is often regarded as the paradigmatic ancient materialism. Leucippus and Democritus (5th century BCE) proposed that reality consists of atoms and void: indivisible, ungenerated, and indestructible particles moving in empty space. Qualities such as color or taste were explained as effects of atomic shapes and motions on human senses.
“By convention sweet, and by convention bitter, by convention hot, by convention cold, by convention color; but in reality atoms and void.”
— Democritus, fragment (via Sextus Empiricus)
Epicurus (341–270 BCE) and his Roman follower Lucretius developed this into a comprehensive natural philosophy. They held that the soul is made of fine atoms dispersed at death, thus denying personal immortality. Epicurus introduced the famous clinamen (swerve) of atoms to account for free action and to break strict determinism.
Other Greek Materialisms
Some scholars interpret the early Milesians (Thales, Anaximander, Anaximenes) and Heraclitus as proto-materialists, since they posited primary stuffs (water, “the boundless,” air, or fire) as the basis of all things. However, their cosmologies often contain religious or symbolic elements, and they did not typically deny the existence of non-material entities in explicit metaphysical terms.
The Stoics (3rd century BCE onward) advanced a sophisticated corporealism, claiming that only bodies truly exist. Even god (identified with a fiery “pneuma”) and the soul were conceived as refined bodies permeating and structuring the cosmos. This has been read by many commentators as a form of materialism, though the Stoics’ emphasis on divine rationality distinguishes their view from more mechanistic atomism.
Indian and Other Traditions
In ancient India, the Cārvāka (Lokāyata) school, known largely through hostile sources, is often described as materialist. It reportedly taught that only perceptible elements exist, that consciousness arises from their combination, and that there is no afterlife or karma. Textual evidence is fragmentary, and some reconstructions are contested, but the Cārvākas are regularly cited as an early non-Western materialist school.
Some early Chinese thinkers, particularly in strands of Mohism and certain naturalistic readings of the Daoist and Confucian traditions, emphasized concrete, observable processes and downplayed spirits, though whether these count as “materialist” in a strict sense is debated given differing ontological categories.
These ancient traditions provided later thinkers with models of explaining the world, including mind and ethics, in terms of material constituents and lawful processes, even when they coexisted with religious practices or theological elements.
5. Early Modern Mechanical Materialism
The early modern period (17th–18th centuries) saw the rise of mechanical materialism, grounded in the new mathematical physics of Galileo and Newton. Matter was conceived as extended, inert substance whose behavior could be described by laws of motion and impact. Mechanical materialists argued that all phenomena, including life and mind, could in principle be explained by such corpuscular interactions.
Hobbes and the Reduction of Mind to Motion
Thomas Hobbes (1588–1679) is often identified as the first systematic early modern materialist in the English tradition. He famously claimed that “the universe… is corporeal; that is to say, body; and that which is not body, is no part of the universe” (Leviathan, I.46). For Hobbes, thinking, sensing, and imagining are modes of motion in the brain and nervous system. Even political structures are analyzed as artificial bodies composed of moving parts.
“Sense is some internal motion in the sentient, generated by some internal motion of the parts of the object.”
— Hobbes, Leviathan, I.1
Gassendi, Descartes’ Critics, and French Materialism
In France, Pierre Gassendi revived atomism and proposed a Christianized corpuscular philosophy, influencing later, more radical thinkers. Materialist authors such as La Mettrie and d’Holbach pushed mechanical explanations to controversial conclusions:
- Julien Offray de La Mettrie, in L’Homme Machine (Man a Machine, 1747), argued that humans are complex automata, and that mental states are functions of bodily organization.
- Paul-Henri Thiry d’Holbach, in Système de la nature (1770), defended a thoroughgoing deterministic materialism in which all events, including human actions, follow necessarily from prior motions of matter.
These writers often defined their views against Cartesian dualism, which posited a distinct res cogitans (thinking substance). Mechanical materialists contended that dualism generated insoluble interaction problems and was unnecessary given advances in physiology and physics.
Core Commitments
Mechanical materialism typically involved:
| Commitment | Content |
|---|---|
| Substance monism | Only matter (extended substance) exists; no immaterial souls or spirits are needed. |
| Mechanistic causation | All changes result from contact interactions, impact, and lawful motion. |
| Mind–body identity or dependence | Mental phenomena are either identical with or fully dependent on bodily (especially brain) processes. |
| Anti-teleology | Explanations in terms of purpose or final causes are replaced by efficient causes. |
While later developments in physics and biology would challenge some mechanistic assumptions (for example, about matter’s inertness or strict determinism), early modern mechanical materialism established many of the argumentative strategies and problematics that would shape subsequent debates about materialism.
6. Enlightenment and 19th-Century Scientific Materialism
From the late Enlightenment through the 19th century, materialist thought increasingly aligned itself with empirical science, particularly physiology, chemistry, and later evolutionary biology. This period is commonly associated with scientific materialism, a movement that claimed that scientific methods and concepts suffice to explain all natural and even mental phenomena.
Enlightenment Radicalism
In the 18th century, French philosophes like La Mettrie, d’Holbach, and Denis Diderot integrated emerging anatomical and physiological knowledge into materialist frameworks. Diderot’s dialogues, such as Le Rêve de d’Alembert (D’Alembert’s Dream), explored the idea that sensation and thought are properties of organized matter, anticipating later notions of emergent complexity.
These Enlightenment thinkers linked materialism with critique of religious authority, skepticism about the soul’s immortality, and calls for social reform, thereby politicizing metaphysical positions.
19th-Century Scientific Materialism
In the mid-19th century, developments in organic chemistry, cell theory, and neurophysiology encouraged more explicit “scientific materialist” programs, particularly in the German-speaking world.
Key figures include:
| Thinker | Work | Characterization of materialism |
|---|---|---|
| Ludwig Büchner | Kraft und Stoff (Force and Matter, 1855) | Asserted that matter and force are indestructible and that all phenomena, including consciousness, are their manifestations. |
| Carl Vogt | Vorlesungen über den Menschen (1863) | Famously compared thought to brain secretion, suggesting a direct dependence of mental life on physiology. |
| Jacob Moleschott | Der Kreislauf des Lebens (1852) | Emphasized metabolic processes and nutrition as the basis of mental and social life. |
Scientific materialists argued that vitalist and spiritualist accounts of life and mind were incompatible with experimental evidence. They drew on advances by physiologists such as Hermann von Helmholtz, who formulated the conservation of energy and studied nerve conduction, to support claims that life processes obey physical laws.
Debates and Reactions
This movement provoked intense controversy:
- The Materialismusstreit (materialism controversy) in German philosophy and theology involved critics such as Rudolf Wagner and Hermann Lotze, who contended that materialism could not account for consciousness, morality, or purposiveness.
- Within science itself, some researchers endorsed methodological naturalism while remaining agnostic or critical about metaphysical materialism.
Scientific materialism also intersected with Darwinian evolution. Many interpreted Charles Darwin’s On the Origin of Species (1859) as lending support to materialist views by explaining biological complexity and human origins without recourse to special creation. Others sought to reconcile evolution with spiritual or teleological interpretations.
By the late 19th century, scientific materialism had become a central reference point in philosophical, theological, and political debates, even as emerging physics (e.g., electromagnetic field theory) and psychology began to challenge its strictly mechanistic assumptions.
7. Marx, Engels, and Historical Materialism
Karl Marx and Friedrich Engels developed a distinctive form of materialism focused on social life and history rather than on the composition of physical substances. While they accepted a broadly naturalistic view of nature, their main innovation was historical materialism, a theory about how societies develop through changes in their material productive conditions.
From Feuerbach to Historical Materialism
Marx and Engels engaged critically with the anthropological materialism of Ludwig Feuerbach, who had argued that theology is a projection of human essence. They praised Feuerbach’s turn to human, sensuous reality but criticized his static conception of “man” and his neglect of praxis (practical activity).
In the Theses on Feuerbach (1845), Marx wrote:
“The philosophers have only interpreted the world, in various ways; the point, however, is to change it.”
He argued that human beings are shaped by their social relations and labor practices, not just by an abstract “species essence.”
Core Claims of Historical Materialism
Historical materialism proposes that:
| Level | Content in Marx and Engels |
|---|---|
| Forces of production | Tools, technologies, skills, and labor power available in a given society. |
| Relations of production | Property relations and class structures (e.g., slave–owner, lord–serf, capitalist–worker). |
| Base and superstructure | The “economic base” (forces and relations of production) conditions the “superstructure” of law, politics, ideology, and culture. |
According to this framework, major historical transformations (e.g., from feudalism to capitalism) arise from contradictions between developing productive forces and existing relations of production. Class struggles express these contradictions and drive change.
Marx’s The German Ideology (with Engels) presents an early systematic exposition:
“The mode of production of material life conditions the general process of social, political and intellectual life.”
Distinctive Features
Historical materialism differs from earlier materialisms by:
- Focusing on social being and economic organization rather than on physical substances alone.
- Treating ideas, religions, and philosophies as products and tools of particular social formations.
- Emphasizing historicity—the idea that social structures are transient and shaped by material conditions.
Interpretations vary over whether Marx and Engels advanced a deterministic model where the economic “base” strictly determines the superstructure, or a more interactive account allowing reciprocal influence. Later Marxist thinkers further developed, revised, or critiqued historical materialism, but the core notion that material productive relations fundamentally structure social life remains central to this tradition.
8. Dialectical Materialism and Marxist Traditions
Dialectical materialism emerged as a codified philosophical framework within Marxist movements, particularly in the late 19th and 20th centuries. It combined a materialist ontology with a dialectical understanding of change, drawing on Hegelian logic while rejecting Hegel’s idealism.
Engels and the “Dialectics of Nature”
Friedrich Engels extended Marx’s historical materialism into a more general worldview. In works such as Anti-Dühring (1878) and the posthumously published Dialectics of Nature, Engels argued that dialectical laws—unity of opposites, transformation of quantity into quality, and negation of the negation—govern processes in nature, society, and thought.
“The great basic thought that the world is not to be comprehended as a complex of ready-made things, but as a complex of processes…”
— Engels, Anti-Dühring
Engels maintained that matter is primary and that consciousness is a product of highly developed material organization (the human brain). He sought to show how dialectical patterns appear in scientific theories, such as the transformation of states of matter or evolutionary development.
Lenin, Soviet Marxism, and Official “Diamat”
In Vladimir Lenin’s Materialism and Empirio-Criticism (1909), dialectical materialism was deployed against neo-Kantian and positivist philosophies. Lenin insisted on the independent existence of material reality and criticized views that reduced objects to sensations or experiences.
In the Soviet Union, dialectical materialism (Diamat) and historical materialism (Istmat) were institutionalized as official philosophies. Textbooks presented a systematized doctrine including:
| Aspect | Typical formulation in Soviet Diamat |
|---|---|
| Ontology | Matter is primary; consciousness is a property of highly organized matter. |
| Dialectics | Universal laws of development through contradiction and negation. |
| Epistemology | Reflection theory: knowledge reflects objective reality, though in a mediated and historically developing way. |
Critics argue that this codification sometimes simplified or dogmatized Marx’s and Engels’ more open-ended analyses.
Western Marxism and Alternatives
Outside official communist parties, Western Marxist thinkers such as Georg Lukács, Antonio Gramsci, Theodor Adorno, Louis Althusser, and others reinterpreted or criticized dialectical materialism:
- Some emphasized praxis, culture, and ideology over a generalized “dialectics of nature.”
- Others questioned whether Engels’ extension of dialectics to nature remained faithful to Marx.
- Certain currents (e.g., Althusser) spoke of a “materialism of the encounter” or “aleatory materialism,” stressing contingency rather than teleology.
In contemporary Marxist debates, “dialectical materialism” can signify anything from a comprehensive natural philosophy to a more modest commitment to analyzing material structures via contradiction, totality, and historical development. Its status as a distinct doctrine, separate from historical materialism, continues to be discussed among scholars.
9. Analytic Physicalism and Contemporary Materialism
In the 20th and 21st centuries, especially in Anglophone analytic philosophy, the term physicalism has largely supplanted “materialism” as the preferred label for views that treat reality as fundamentally physical. Contemporary materialism is thus often discussed under the heading of analytic physicalism, though some authors still use “materialism” historically or interchangeably.
From Logical Positivism to Identity Theory
Early analytic debates were shaped by logical positivism, which emphasized verification and the language of physics. Later, mid-century philosophers such as J. J. C. Smart and U. T. Place proposed the type-identity theory: mental states are identical with physical (brain) states.
“Sensations are nothing over and above brain processes.”
— Smart, “Sensations and Brain Processes” (1959)
Supervenience, Functionalism, and Non-Reductive Physicalism
As objections to strict identity theories emerged (for instance, about multiple realizability of mental states), physicalists developed more sophisticated accounts:
| Version | Core idea |
|---|---|
| Functionalist physicalism | Mental states are functional roles realized by physical systems; their identity is given by causal roles, not by specific neural types. |
| Supervenience physicalism | There can be no change in mental properties without some change in underlying physical properties, though the relation may not be reducible to identity. |
| Non-reductive physicalism | Everything is physically realized, but higher-level properties (e.g., mental, biological) are not straightforwardly reducible to physics. |
Philosophers like David Lewis, David Papineau, and Frank Jackson (before his later revisions) contributed significantly to articulating these positions.
Contemporary Debates and Extensions
Current discussions of materialism/physicalism intersect with:
- Philosophy of mind, especially debates about consciousness, qualia, and mental causation.
- Metaphysics, including questions about reduction, emergence, and the ontology of properties.
- Philosophy of science, where physicalism is assessed in light of the structure of contemporary physics (fields, quantum theory, spacetime).
Some theorists advocate reductionist physicalism, aiming to derive all facts from microphysical facts. Others propose emergent or layered pictures where complex systems exhibit novel, though physically grounded, properties.
There is also ongoing discussion about how to define “the physical.” Options include:
- A theory-based approach (whatever our best physical theory posits).
- A role-based approach (entities playing certain causal–structural roles).
- A via negativa approach (non-mental, non-normative, etc.).
These definitional strategies affect how inclusive or exclusive physicalism is and how it relates to other naturalist positions. Contemporary materialism thus encompasses a range of positions unified by the claim that all phenomena ultimately depend on what physics (broadly construed) describes, while differing about reduction, emergence, and the exact scope of the “physical.”
10. Conceptual Analysis: Matter, Mind, and the Physical
Materialist doctrines hinge on how matter, mind, and the physical are conceived. Over time, these concepts have shifted significantly, leading to different formulations of materialism.
Concepts of Matter and the Physical
Historically, matter was associated with:
- Substantial stuff occupying space (Aristotelian and early modern views).
- Particles or corpuscles with mass and motion (mechanical philosophy).
- Later, fields, energy, and quantum entities that challenge simple “solid substance” pictures.
In contemporary discussions, “the physical” often replaces “matter”:
| Conception | Characterization |
|---|---|
| Substance-based | Physical entities are extended, mass-bearing stuff. |
| Theory-based | Physical entities are whatever is posited by our best physical theories. |
| Role-based | Physical entities are those that occupy certain causal–structural roles (e.g., spacetime–causal structure). |
Materialism/physicalism is then formulated as the view that all entities either are physical in one of these senses or are fully dependent on, realized by, or supervenient upon the physical.
Concepts of Mind
Philosophical accounts of mind range widely:
- Substance dualism treats mind as a distinct kind of substance (e.g., Cartesian res cogitans).
- Property dualism posits irreducible mental properties instantiated by physical substances.
- Materialist views treat mental phenomena as either identical with, dependent upon, or emergent from physical states.
Within materialism, major distinctions include:
| View | Mental–physical relation |
|---|---|
| Identity theories | Mental states are numerically identical to brain states or neural processes. |
| Functionalism | Mental states are functional roles implemented by physical systems. |
| Eliminativism | Common-sense mental categories (beliefs, desires) are mistaken and may be replaced by neuroscientific descriptions. |
| Emergent materialism | Mental properties emerge from complex physical systems and have novel features, while remaining grounded in the physical. |
Dependence Relations
Materialism can be more or less strong depending on the dependence relation it posits:
- Strict reduction: Higher-level phenomena can be derived from or reduced to physical facts.
- Supervenience: No difference at the mental or social level without some physical difference, but perhaps no full reduction.
- Realization: Higher-level properties are instantiated by physical configurations that play certain roles.
Discussions also address whether causal closure of the physical holds: that every physical event has a sufficient physical cause. Materialists often endorse this principle, using it to resist interactionist forms of dualism, though some emergentist materialists explore more complex causal pictures.
These conceptual distinctions provide the background for more specific debates about whether materialism can accommodate consciousness, normativity, or social phenomena, and how it compares with competing ontologies.
11. Materialism in Philosophy of Mind and Consciousness
The philosophy of mind has been a central arena for evaluating materialism. The key question is whether consciousness, intentionality, and other mental phenomena can be fully understood in physical terms.
Behaviorism and Early Identity Theories
Mid-20th-century behaviorism (e.g., Ryle, early analytical philosophy) treated mental states as dispositions to behave, partly sidestepping ontology. As this approach faced limitations, identity theories (Smart, Place) proposed that sensations and other mental states are identical with brain states.
Identity theories aimed to capture:
- The causal efficacy of mental states (since brain states are clearly causal).
- The possibility of empirical correlations between reported experiences and neural events.
Functionalism and Computational Models
Functionalism reconceived mental states as defined by their causal roles in a system, not by their physical makeup. This opened the door to:
- Multiple realization (the same mental state realized in different physical substrates).
- Comparisons between brains and computational systems.
Materialists sympathetic to functionalism generally hold that these functional roles are, in fact, realized by physical systems.
Consciousness and the “Hard Problem”
Contemporary debates intensify around phenomenal consciousness—the subjective “what it is like” of experience. Critics argue that materialism struggles with:
- Qualia: allegedly irreducible qualitative aspects of experience.
- The explanatory gap between physical processes and subjective experience.
- The hard problem of consciousness (Chalmers), which questions why particular physical processes should give rise to experience at all.
Materialist responses include:
| Strategy | Characterization |
|---|---|
| Reductive accounts | Attempt to reduce phenomenal properties to functional or neural properties (e.g., higher-order thought theories, representationalism). |
| Type‑B materialism | Accept an explanatory gap but deny ontological dualism, suggesting that conceptual limitations explain our difficulties. |
| Phenomenal concept strategy | Argue that special concepts of experience mislead us into positing non-physical properties. |
| Eliminativism about qualia | Question the coherence or theoretical utility of qualia as traditionally conceived. |
Some theorists explore panpsychism or Russellian monism, which treat consciousness as fundamental or as rooted in the intrinsic nature of physical properties. There is debate about whether these positions count as forms of materialism, modified physicalism, or departures from materialism altogether.
Mental Causation and Free Will
Materialism also faces questions about mental causation (how mental states can have causal impact if everything is physically caused) and free will (whether physical determinism is compatible with agency). Proposed solutions include:
- Non-reductive physicalism with causal exclusion worries addressed via realization or interventionist accounts.
- Compatibilist views of free will that reinterpret agency in physically realizable terms.
These debates continue to shape assessments of whether materialism, broadly construed, can provide an adequate theory of mind and consciousness.
12. Materialism in Social and Political Theory
Beyond metaphysics, materialism has been central to social and political theory, where it typically designates approaches that prioritize material conditions, economic structures, and bodily life in explaining social phenomena.
Marxist Materialisms
Historical materialism (section 7) and dialectical materialism (section 8) represent the most influential social materialisms. They focus on:
- Modes of production (e.g., feudalism, capitalism) as structuring social relations.
- Class struggle as expressing material conflicts of interest.
- The economic “base” as conditioning legal, political, and ideological “superstructures.”
These ideas have informed analyses of state power, ideology, and cultural practices, suggesting that beliefs and institutions often serve to stabilize or challenge material class arrangements.
Non-Marxist and Neo-Marxist Materialisms
Other strands of social theory have adopted materialist orientations without necessarily embracing classical Marxism:
| Approach | Materialist emphasis |
|---|---|
| Institutional and structural sociology (e.g., Weberian traditions) | Analysis of bureaucratic structures, markets, and law as concrete frameworks of social life. |
| Feminist materialism | Focus on the material conditions of gendered labor, reproduction, and embodiment; critiques of purely discursive accounts of gender. |
| New materialisms | Attention to non-human and environmental agencies, bodies, and infrastructures; sometimes influenced by Deleuze and science studies. |
Neo-Marxist theorists such as Louis Althusser and Nicos Poulantzas developed “structural” or “state” materialisms that analyze institutions and ideologies in terms of their roles in reproducing material relations of production.
Materialist Explanations vs. Idealist and Cultural Accounts
In social theory, “materialism” often contrasts with:
- Idealist histories that foreground ideas, great individuals, or cultural meanings as primary drivers.
- Purely cultural or discursive theories that treat material factors as derivative or secondary.
Materialist approaches typically argue that:
- Access to resources, labor, and technology shapes social possibilities and constraints.
- Embodied needs (food, shelter, health) and economic dependencies play a decisive role in social organization.
- Ideologies and cultures are best understood in relation to these material conditions.
However, there is significant internal debate over:
- The degree of causal primacy assigned to economic structures.
- How to integrate symbolic, discursive, and affective dimensions into a materialist framework.
- Whether contemporary forms of power (e.g., digital platforms, global finance) require revised forms of materialism.
Materialism in social and political theory thus denotes a range of perspectives unified by their insistence that any adequate account of social life must grapple with the material organization of production, reproduction, and embodiment.
13. Related and Contrasting Doctrines
Materialism is best understood in relation to alternative ontological and methodological positions with which it has been historically contrasted or allied.
Idealism
Idealism holds that reality is fundamentally mental, spiritual, or idea-like. Examples include:
- Platonic traditions where forms or ideas are ontologically primary.
- Berkeleian immaterialism, which denies the existence of matter altogether.
- German Idealism (e.g., Hegel), where reality is a manifestation of absolute spirit or reason.
Materialists typically oppose these views by asserting the primacy of matter or the physical, though some positions (e.g., certain forms of neutral monism or panpsychism) blur the sharp dichotomy.
Dualism
Dualism posits two fundamentally different kinds of substance or property, typically mind and matter. Cartesian substance dualism is the classical example. Materialists usually reject dualism on grounds of:
- The interaction problem (how distinct substances could causally interact).
- The apparent success of physical explanations.
Property dualists, however, may accept a physical substrate while positing irreducible mental properties, creating intermediate positions between robust materialism and dualism.
Naturalism
Naturalism is a broader outlook holding that reality is governed by natural laws and is in principle explainable by the natural sciences. Many materialists are naturalists, but:
| View | Relation to materialism |
|---|---|
| Naturalism | Does not necessarily deny non-physical entities if they fit into a scientific worldview (e.g., some abstract objects). |
| Materialism/Physicalism | More specifically claims that all concrete entities are material/physical or physically realized. |
Thus, materialism can be seen as a stronger thesis within the naturalist family.
Reductionism and Emergentism
Reductionism and emergentism are methodological and metaphysical stances that cut across the materialism/idealism divide but are often discussed in connection with materialism:
- Reductionist materialism maintains that higher-level phenomena (biological, mental, social) can be fully explained in terms of lower-level physical processes.
- Emergentist materialism allows that new properties arise at higher levels of complexity, while remaining grounded in the physical.
Critics sometimes associate materialism with reductive excess; proponents of emergentist or non-reductive forms aim to combine materialist commitments with recognition of higher-level autonomy.
Physicalism, Monism, and Neutral Monism
Physicalism is frequently treated as the contemporary successor to classical materialism (section 9). Both are forms of monism, which asserts a single basic kind of substance or property. Other monist views, such as neutral monism, propose a fundamental “neutral” stuff underlying both mental and physical aspects. Whether such views count as materialist is debated, depending on how “neutral” base is characterized and whether it is ultimately identified with the physical.
These related and contrasting doctrines frame the options for thinking about the basic structure of reality and clarify what is distinctive about materialism’s emphasis on the primacy of matter or the physical.
14. Translation Challenges and Cross-Cultural Reception
Translating “materialism” across languages and intellectual traditions poses both linguistic and conceptual difficulties. The term often carries overlapping metaphysical, ethical, and cultural connotations that do not map neatly onto other vocabularies.
Linguistic Ambiguities
In many European languages, a single word (e.g., Materialismus, matérialisme, materialismo) covers both:
- The philosophical doctrine that only matter or the physical exists.
- The moral–cultural attitude of excessive concern with wealth and possessions.
This can blur distinctions between, for example, a metaphysical materialist and a person criticized for consumerism. Translators and scholars often need to clarify context, sometimes using qualifiers like “philosophical materialism” or “ethical materialism.”
Non-European Contexts
In other philosophical cultures, the challenges are deeper:
| Tradition | Issues in rendering “materialism” |
|---|---|
| Classical Chinese | No indigenous category of “matter” identical to Western usage; terms like 物 (wu, things) or 氣 (qi, vital material force) only partially overlap. Debates about how to classify some Confucian, Daoist, or Mohist positions as “materialist” are ongoing. |
| Indian philosophy | Schools like Cārvāka are often translated as “materialist,” but their focus on perceptible elements and rejection of afterlife do not always align with later Western metaphysical materialism. |
| Islamic philosophy | Terms like māddīya (materialism) developed in modern contexts to translate European concepts; earlier falsafa did not use an identical category, complicating retrospective classifications. |
Modern translations of Marxist texts have often standardized “materialism” to render Materialismus, creating the impression of strict conceptual equivalence, even where underlying ontologies diverge.
Conceptual Reframing
In cross-cultural reception, “materialism” has sometimes been reinterpreted to fit local debates:
- In some East Asian Marxist traditions, “materialism” was tied to indigenous notions of qi or practical activity, generating hybrid frameworks.
- In certain postcolonial contexts, “materialism” has been associated with developmentalism, technology, or scientific rationality, rather than with strict metaphysical theses.
Furthermore, modern physics’ redefinition of matter (fields, quantum states) raises questions about whether “materialism” should be translated as physicalism or naturalism in philosophical contexts, especially where the term “matter” has strongly pre-scientific connotations.
Translators and comparativists thus face choices about whether to:
- Preserve historical terms (e.g., Materialismus, māddīya) and explain their evolution.
- Opt for broader labels like naturalism or realism where “matter” is not a fundamental category.
- Coin new expressions to capture specific strands (e.g., “historical materialism,” “dialectical materialism”) in local conceptual idioms.
These choices significantly shape how materialism is understood and debated across cultures.
15. Critiques of Materialism from Theology and Idealism
Materialism has elicited sustained criticism from theological traditions and idealist philosophies, which challenge both its metaphysical claims and its alleged ethical or cultural implications.
Theological Critiques
From Jewish, Christian, Islamic, Hindu, Buddhist, and other religious perspectives, typical concerns include:
| Objection | Rationale |
|---|---|
| Denial of the soul or spirit | Materialism is seen as incompatible with doctrines of an immaterial, immortal soul or spiritual dimensions of reality. |
| Undermining morality and meaning | Critics contend that if humans are purely material, objective moral values, free will, and ultimate meaning become difficult to ground. |
| Reduction of religious experience | Mystical and religious experiences are reinterpreted as brain states or social phenomena, which many theists view as explanatory reductions that miss their true significance. |
Theologians such as Rudolf Wagner in the 19th century argued against scientific materialism, claiming that it offered no adequate account of conscience, freedom, or purpose. Contemporary religious philosophers similarly suggest that materialism cannot explain the apparent intentionality and normativity of human life.
Idealist and Philosophical Critiques
Idealist philosophers present more systematic metaphysical objections:
- Kantian lines of critique argue that we only know appearances structured by our cognitive faculties, making materialism’s claims about things in themselves speculative.
- Hegelian idealism maintains that reality is rational and conceptually structured, with material nature understood as a moment within a larger spiritual or logical whole. On this view, materialism is seen as one-sided, ignoring the formative role of thought.
- Berkeleyan immaterialism contends that our immediate awareness is of ideas, not of matter, and that postulating material substance is unnecessary and incoherent.
Idealists often claim that materialism cannot account for:
| Issue | Idealist contention |
|---|---|
| Consciousness | Subjective awareness is irreducible to physical processes. |
| Normativity and logic | Laws of logic and moral norms do not seem material or reducible to physical facts. |
| Intentionality | The “aboutness” of thought (its directedness toward objects) is difficult to capture in purely physical terms. |
Cultural and Ethical Concerns
Both theological and idealist critics sometimes link materialism to:
- Relativism or nihilism, on the assumption that if only matter exists, higher values lack objective status.
- Consumerism or hedonism, associating metaphysical materialism with cultural “materialism” and suggesting that it encourages focus on material success.
Materialists and their sympathizers typically respond by distinguishing ontological claims from ethical attitudes and by developing naturalistic accounts of morality, rationality, and meaning. Nonetheless, these critiques continue to shape public and academic debates about the adequacy and implications of materialist worldviews.
16. Scientific Developments and the Redefinition of Matter
Materialism has been repeatedly reshaped by changes in the scientific understanding of matter and the physical world. What counts as “material” or “physical” has evolved from solid substances to complex quantum fields and spacetime structures.
From Classical Mechanics to Fields
In the 17th and 18th centuries, matter was typically conceived as solid, impenetrable particles. Newtonian mechanics reinforced this view, though Newton’s own gravitational theory introduced action at a distance, which some materialists found problematic.
In the 19th century, electromagnetism and field theory complicated this picture:
- James Clerk Maxwell’s equations described fields—continuous distributions of energy in space—challenging the idea that only particles are fundamental.
- Discussions about the ether and later its rejection in relativity theory raised questions about the “substance” of space and fields.
Materialists responded by broadening their concept of matter or by shifting from “materialism” to more inclusive physicalism.
Relativity and Quantum Mechanics
20th-century physics further transformed conceptions of the physical:
| Theory | Impact on “matter” |
|---|---|
| Special and general relativity | Unified space and time into spacetime; mass and energy became interconvertible (E=mc²), eroding simple mass-based notions of matter. |
| Quantum mechanics and quantum field theory | Introduced wave–particle duality, probabilistic behavior, and fields as fundamental entities; particles became excitations of quantum fields. |
These developments have led many philosophers to argue that traditional “matter” is no longer an adequate basic category. Instead, materialism is reformulated as physicalism: the doctrine that everything is as described by, or dependent on, the entities and laws of fundamental physics, however counterintuitive.
Biology, Neuroscience, and Cognitive Science
Advances in evolutionary biology, genetics, neuroscience, and cognitive science have also influenced materialist thought:
- Evolution provides a naturalistic account of the origin and diversification of life, often cited as supporting materialist explanations of complex organisms and behaviors.
- Neuroscience maps correlations between mental functions and brain activity, reinforcing claims that mental states depend on neural processes.
- Cognitive science models cognition using computational and dynamical systems frameworks, which many interpret in physically realizable terms.
Some argue that these sciences support reductionist materialism; others see them as revealing multi-level explanations where higher-level properties retain a degree of autonomy despite underlying physical bases.
Ongoing Challenges
Scientific developments also raise questions for materialism:
- Quantum nonlocality and indeterminacy challenge straightforward deterministic pictures often associated with classical materialism.
- Debates about information, entropy, and complex systems introduce new candidates for fundamental explanatory roles, provoking discussion about whether they are reducible to standard physical categories.
Consequently, contemporary materialists frequently articulate their views in flexible terms that track current best physics, acknowledging that as physics evolves, so too may the content of “the physical” that underpins materialist commitments.
17. Materialism and Contemporary Culture (Consumerism, Secularism)
In contemporary cultural discourse, “materialism” often refers not to a metaphysical thesis but to attitudes and social patterns centered on material goods, consumption, and this-worldly concerns. These cultural senses interact in complex ways with philosophical and religious uses of the term.
Consumer Culture and “Materialistic” Values
Sociologists and cultural critics commonly use “materialism” to describe:
- High valuation of wealth, possessions, and consumption.
- Identity formation through brands, commodities, and lifestyle choices.
- Emphasis on economic success as a primary measure of achievement.
Empirical research in psychology sometimes operationalizes materialistic values and investigates their association with well-being, social relationships, and environmental attitudes. Findings often suggest correlations between strong materialistic orientations and lower life satisfaction or higher ecological footprints, though interpretations vary.
Religious and moral critics frequently condemn such cultural materialism as fostering superficiality, individualism, or moral decline, sometimes linking it—fairly or not—to philosophical materialism.
Secularization and This-Worldliness
“Materialism” is also invoked in discussions of secularization and the declining social role of organized religion, especially in Western contexts. Here it may denote:
| Usage | Content |
|---|---|
| Secular materialism | A worldview that treats this life and the physical universe as the only relevant realities, often without explicit metaphysical argument. |
| Practical materialism | Focus on practical, worldly concerns (work, politics, technology) rather than spiritual matters. |
Some secular thinkers embrace “materialist” as a positive descriptor of a this-worldly ethics grounded in human needs and capacities. Others prefer terms like humanism or naturalism to avoid the consumerist associations of “materialism.”
Distinguishing Philosophical and Cultural Materialism
Analysts often distinguish:
- Philosophical materialism: claims about the nature of reality (sections 1–10).
- Cultural or ethical materialism: value orientations prioritizing material goods.
- Sociological materialism: emphasis on material conditions and infrastructures in explaining social life (section 12).
Conflation of these senses can lead to misunderstandings. For instance, a person might endorse a metaphysical materialism while living an ascetic lifestyle, or a religious believer might participate fully in consumer culture. Nonetheless, in public debates, metaphysical materialism is sometimes associated—positively or negatively—with modern consumer societies, technological progress, and secularization.
These cultural uses of “materialism” thus shape broader perceptions of the doctrine, influencing whether it is seen as liberating (freeing thought from superstition) or impoverishing (reducing human life to consumption and production).
18. Legacy and Historical Significance
Materialism has played a significant role in the development of philosophy, science, and social thought, leaving a complex legacy that continues to inform contemporary debates.
Impact on Science and Epistemology
Materialist and later physicalist assumptions have underpinned much of modern science’s methodological naturalism:
- By insisting that natural phenomena can be explained without recourse to immaterial agencies, materialism has encouraged empirical investigation and mechanistic modeling.
- At the same time, shifting scientific conceptions of matter have forced ongoing revisions of materialist doctrines, illustrating a reciprocal influence between metaphysics and scientific theory.
Materialist critiques of teleological and vitalist explanations contributed to the rise of experimental physiology, evolutionary biology, and neuroscience.
Influence on Social and Political Movements
In social and political theory, materialist frameworks—especially Marxist ones—have shaped:
- Analyses of capitalism, imperialism, and class relations.
- Strategies for revolutionary movements and labor organizing.
- Critiques of ideology, religion, and law as expressions of material power structures.
These ideas have informed diverse political projects, from socialist and communist movements to critical and postcolonial theories, while also provoking counter-movements grounded in religious, liberal, or idealist perspectives.
Ongoing Philosophical Debates
Materialism remains central to many contemporary philosophical discussions:
- In philosophy of mind, debates over consciousness, free will, and mental causation largely revolve around assessing various materialist or physicalist positions.
- In ethics and metaethics, questions about whether moral values can be naturalized relate to broader materialist or non-materialist frameworks.
- In metaphysics, disputes over reductionism, emergence, and the ontology of social entities engage with materialist commitments about dependence on the physical.
Cultural and Intellectual Symbolism
Materialism has also functioned as a symbolic marker in wider culture:
- For some, it represents scientific rationality, emancipation from superstition, and focus on improving material conditions.
- For others, it symbolizes spiritual impoverishment, consumerism, or the neglect of transcendent values.
Because the term has carried both technical philosophical meanings and popular evaluative connotations, its historical significance lies not only in specific doctrines but also in the controversies it has sparked across theology, politics, and culture.
Taken together, the diverse forms of materialism—from ancient atomism to contemporary physicalism and social materialisms—have provided enduring vocabularies for thinking about how matter, life, mind, and society are related, ensuring that the concept remains a central reference point in philosophical and interdisciplinary inquiry.

Matter / the physical
The basic ‘stuff’ or domain of reality that materialists claim is fundamental; historically understood as extended substance or particles, and in contemporary views as whatever is posited by our best physical theories (fields, particles, spacetime structures, etc.).
Materialism (metaphysical sense)
The doctrine that reality is fundamentally material or physical: everything that exists is either material or wholly dependent on material/physical processes.
Physicalism
A contemporary form of materialism which holds that all entities and properties either are physical or are fully determined by the entities and laws described by fundamental physics.
Historical materialism
Marx’s theory that the mode of production—combining productive forces and relations of production—fundamentally conditions social, political, and intellectual life, and that historical change is driven by material economic contradictions and class struggle.
Dialectical materialism
A Marxist framework, developed especially by Engels and later Marxists, which combines a materialist ontology with a dialectical logic of development through contradictions, applying these patterns to nature, society, and thought.
Mechanistic / scientific materialism
Mechanistic materialism explains all phenomena (including life and mind) in terms of the motions and impacts of inert bodies; scientific materialism is the 18th–19th‑century movement claiming that physics, chemistry, and physiology suffice in principle to explain all aspects of reality.
Reductionism vs. emergentism
Reductionism holds that higher-level phenomena (biological, mental, social) can be fully explained in terms of lower-level physical processes. Emergentism holds that new, not straightforwardly reducible properties arise from complex material systems, even though they depend on the physical.
Dualism and idealism (contrasting doctrines)
Dualism posits two fundamentally different kinds of reality (typically mind and matter); idealism holds that reality is fundamentally mental or spiritual.
How does the shift from ancient atomism to early modern mechanical materialism change the way ‘matter’ is understood, and what philosophical problems does each version aim to solve?
In what ways does historical materialism differ from earlier, more ‘metaphysical’ forms of materialism, and why did Marx and Engels think a focus on social relations and production was necessary?
Can non-reductive or emergent forms of materialism adequately account for consciousness without collapsing into dualism or idealism?
Is physicalism simply ‘updated materialism,’ or does it represent a deeper conceptual shift in how philosophers think about the basic constituents of reality?
How do theological and idealist critiques (section 15) target different aspects of materialism, and which do you find more philosophically challenging for contemporary physicalism?
To what extent should we treat Marx’s historical materialism as ‘economically deterministic’? How does the base–superstructure model allow (or fail to allow) for the autonomy of politics, law, and culture?
Does the cultural use of ‘materialism’ to describe consumerism and secularism (section 17) help or hinder public understanding of philosophical materialism?
