Video Idealism vs materialism mind and matter
Core Argument¶
The central thesis is that the fundamental divide in philosophy — between idealism and materialism — is not an abstract academic dispute but a battle with profound political consequences. The article argues that idealism, in its various historical forms, ultimately serves to justify the existing social order by positing that reality is either a product of mind, spirit, or divine will, thereby rendering material conditions secondary and changeable only through consciousness. Materialism, by contrast, insists that the material world — including the social relations of production — is primary, objective, and governed by knowable laws. Marxism completes this materialist tradition by extending it to history and society, providing the theoretical basis for revolutionary transformation. The claim is that every philosophical position carries a political charge, and that the choice between idealism and materialism is ultimately a choice between accommodation and revolution.
Theoretical Grounding¶
The analysis draws on the classical Marxist tradition of philosophical materialism, tracing its lineage from the ancient atomists (Democritus, Epicurus) through the bourgeois materialists of the Enlightenment (Diderot, Holbach, Feuerbach) to Marx and Engels' dialectical materialism. It situates itself within Engels' formulation in Ludwig Feuerbach and the End of Classical German Philosophy — the division of philosophy into the two great camps of idealism and materialism according to how they answer the "basic question" of the primacy of mind or matter. The article also draws on Lenin's Materialism and Empirio-Criticism in its insistence on the objective reality of the material world, knowable through practice. The argument is firmly within the orthodox Marxist tradition: it rejects both vulgar materialism (which denies the specificity of consciousness) and all forms of idealism (including "soft" idealisms that treat ideas as autonomous forces in history). The political corollary — that idealism leads to reformism and passivity — is a settled position of the Marxist tradition, not an innovation.
Conjunctural Relevance¶
The article was published in 2019, a period of deepening capitalist crisis and political instability. The argument connects to the contemporary conjuncture in several ways. First, the rise of postmodernist and post-truth ideologies — which deny the possibility of objective knowledge about the world — represents a new form of idealism that paralyses political action. If there is no material reality to be known, only competing narratives, then the working class cannot discover the laws of motion of capitalism and cannot act to overthrow it. Second, the resurgence of religious and spiritualist worldviews, including in ostensibly left-wing forms (e.g., "secular spirituality," New Age politics), functions as a diversion from material struggle. Third, the article implicitly addresses the reformist politics that dominate the labour movement: reformism, by treating capitalism as a system that can be gradually moralised or regulated rather than overthrown, rests on an idealist conception that ideas and good intentions can change material reality without confronting the logic of accumulation. The article names no specific political forces, but its targets are clear: the entire spectrum of opportunism that refuses to draw revolutionary conclusions from the crisis of capitalism.
Where the Argument Continues¶
This article is an introductory exposition of philosophical first principles. It leaves underdeveloped the specific application of dialectical materialism to political economy — that is, how the materialist method reveals the laws of motion of capitalism (the tendency of the rate of profit to fall, crises of overaccumulation, the role of fictitious capital). These arguments are developed extensively elsewhere in the IDOM corpus, particularly in articles on Marxist economics and crisis theory. The article also does not engage with the more sophisticated idealist currents within contemporary academic Marxism (e.g., the "new dialectics" of thinkers like Christopher Arthur or the value-form school), which claim to be materialist but reintroduce idealist categories. These are addressed in other IDOM pieces on the dialectic and on Marx's method. The political implications — the concrete critique of reformist parties and trade union bureaucracies — are taken up in the Against the Stream podcast and in articles on the strategy of the revolutionary party.
Connections¶
This article should be read alongside Engels' Ludwig Feuerbach and the End of Classical German Philosophy and Socialism: Utopian and Scientific, Lenin's Materialism and Empirio-Criticism and The Three Sources and Three Component Parts of Marxism, and Plekhanov's The Development of the Monist View of History. Within the IDOM corpus, it connects to articles on dialectics, the Marxist theory of knowledge, and the critique of reformism. It also connects to the broader Marxist tradition's polemics against philosophical revisionism, from Bernstein's "Kant against Marx" to Althusser's structuralist Marxism, which reintroduced idealist elements through the concept of "theoretical practice."
Key Quotes¶
"The fundamental question of philosophy is the question of the relationship between mind and matter, between thinking and being. The answer to this question divides philosophers into two great camps: the idealists and the materialists."
"Idealism, in all its forms, ultimately leads to a passive, contemplative attitude towards the world. If reality is ultimately a product of mind or spirit, then changing reality is a matter of changing ideas — not of transforming material conditions through revolutionary practice."
"Materialism does not deny the existence of consciousness or the power of ideas. What it insists is that consciousness is a product of matter organised in a certain way — the human brain — and that ideas reflect, however imperfectly, the material world."
"The history of philosophy is the history of the struggle between these two tendencies, a struggle that reflects the class struggle in society. The ruling class has always had an interest in promoting idealism, because it diverts attention from the material roots of exploitation."
"Marxism is not just a materialist philosophy; it is a dialectical materialist philosophy. This means it understands the material world not as a static collection of things, but as a process of constant change and development, driven by internal contradictions."
"The test of any philosophy is not its internal consistency or its aesthetic appeal, but its ability to guide revolutionary practice. By this test, materialism has proved itself, while idealism has always led, in the final analysis, to accommodation with the existing order."
