Marx's Revolution in Philosophy - Reflections on the Theses on Feuerbach

Marxist Theory · 2026-05-13

Core Argument

The central thesis is that Marx's Theses on Feuerbach constitute a genuine revolution in philosophy, not merely a correction of Feuerbach's materialism. The article argues that Marx broke decisively with the entire tradition of contemplative materialism by grounding consciousness, knowledge, and truth in practical, sensuous human activity — above all, in collective labour. The epistemological question ("how do we know the world?") is shown to be a false problem, arising only when consciousness is artificially separated from the material body and from the world it inhabits. The real question is not theoretical but practical: truth is proved in action, not contemplation.

The article further claims that this philosophical revolution has direct political implications. The Third Thesis on Feuerbach — with its insistence that changing circumstances and self-change coincide only in revolutionary practice — provides the theoretical foundation for rejecting both mechanical materialism (which sees humans as passive products of circumstance) and idealist voluntarism (which imagines consciousness can transcend material conditions independently). The conclusion is unambiguous: to revolutionise thought, one must revolutionise society.

Theoretical Grounding

The analysis draws on several interconnected Marxist concepts:

Dialectical materialism is the overarching framework. The article rejects the mechanical materialism of the French Enlightenment and Feuerbach, which treats humans as passive recipients of sensory impressions, while also rejecting Hegelian idealism, which subordinates material practice to the self-movement of the Concept. Marx's dialectic is presented as the unity of materialism and activity — matter that acts upon itself through human labour.

The primacy of labour is the central explanatory category. Drawing on Engels's insight that "the hand developed the brain," the article traces the emergence of consciousness through the evolution of manual labour, tool-making, and collective social activity. Consciousness is not a mysterious substance but the mode of existence of a brain that evolved through practical engagement with the material world.

Alienation is deployed to explain the persistence of idealist and contemplative philosophies under capitalism. Bourgeois society atomises individuals, separates mental from manual labour, and presents social relations as natural and eternal. This material alienation produces ideological alienation — the sense that thought is separate from the world, that "reason becomes unreason," that individuals are powerless before forces they cannot control.

The unity of theory and practice is the article's organising principle. The Second Thesis on Feuerbach is read not as an epistemological claim about verification but as a revolutionary ontological claim: thinking is a form of practical activity, and its truth or falsity is determined in the totality of human sensuous practice, not in the isolated mind.

The article sits firmly within the orthodox Marxist tradition associated with Engels, Lenin, and Trotsky. It explicitly rejects the Western Marxist tendency to separate Marx from Engels or to treat the dialectics of nature as a distortion. The debt to Engels's Dialectics of Nature and The Part Played by Labour in the Transition from Ape to Man is explicit and unapologetic.

Conjunctural Relevance

The article was published in May 2013, in the aftermath of the global financial crisis of 2008-9 and the early stages of the austerity regimes imposed across Europe. The conjuncture is addressed indirectly but unmistakably:

The crisis of bourgeois ideology is the immediate political context. The article notes that "the emptiness of modern bourgeois philosophy reflects this idea perfectly, as in the vacuous platitudes of Post-Modernism." The reference is to the intellectual climate of the post-2008 period, when the certainties of neoliberal ideology had been shattered but no coherent alternative had yet emerged. Post-modernist relativism — the denial of objective truth, the reduction of knowledge to discourse — served as the ideological accompaniment to capitalist decay.

The material basis of irrationalism is identified in the lived experience of alienation under capitalist crisis. The article observes that "men and women feel that they have lost control of their lives, that they are being displaced by strange and incomprehensible forces that are beyond their control." This is a direct characterisation of the subjective experience of the 2008-13 period: mass unemployment, housing repossessions, the apparent powerlessness of national governments before financial markets, the sense that "the economy" had become a natural force beyond human intervention.

The political implications are drawn sharply. If truth is proved in practice, and if revolutionary practice is the only way to change both circumstances and human nature, then reformism is philosophically incoherent. The article's insistence that "to revolutionise thought it is necessary to revolutionise society" is a direct polemic against the politics of accommodation that characterised the mainstream labour movement in the austerity period — the idea that capitalism could be "reformed" or "regulated" without being overthrown.

The reference to popular culture — the Terminator films — is not incidental. The article identifies in the fascination with robots escaping human control a cultural expression of the real subordination of people to things under capitalism. This is a conjunctural observation: the early 2010s saw a wave of science fiction exploring themes of technological alienation, from Her to Ex Machina, reflecting a society in which technological advance had become indistinguishable from social regression.

Where the Argument Continues

The article is a philosophical introduction, not a political programme. It leaves several lines of argument open:

The relationship between the Theses on Feuerbach and Marx's later work is asserted but not developed. The article does not trace how the philosophical revolution of 1845 is carried forward into Capital — how the categories of commodity fetishism, the labour process, and the tendency of the rate of profit to fall are themselves applications of the method announced in the Theses. This is taken up in other IDOM articles, particularly those on Marx's method and the dialectic.

The critique of post-modernism is gestured at but not elaborated. The article names post-modernism as "vacuous platitudes" but does not engage with its specific claims or its social roots in the defeat of the workers' movement. This critique is developed more fully in Alan Woods's The History of Philosophy series and in articles on the ideological crisis of the left.

The transition from alienation to revolution is stated as a necessity but not concretised. The article argues that abolishing alienation requires abolishing its material base, but does not discuss the political strategy — the role of the party, the question of the state, the relationship between economic and political struggle — by which this abolition is to be achieved. These questions are addressed in the broader corpus of IDOM articles on revolutionary strategy, the united front, and the transition to socialism.

The scientific account of consciousness is presented as a vindication of materialism, but the article does not engage with the more sophisticated forms of idealism that have adapted to scientific findings — for example, the "hard problem of consciousness" in analytic philosophy, or the various forms of non-reductive physicalism. The argument would need to be extended to address these challenges, as it is in IDOM articles on the philosophy of science.

Connections

The article should be read alongside:

Engels, The Part Played by Labour in the Transition from Ape to Man — the direct source for the argument that manual labour drove the evolution of the brain and consciousness.

Engels, Ludwig Feuerbach and the End of Classical German Philosophy — the classic exposition of the relationship between Marx, Hegel, and Feuerbach, and the text that first established the canonical reading of the Theses on Feuerbach.

Lenin, Materialism and Empirio-Criticism — the most systematic defence of the reflection theory of knowledge within the Marxist tradition, which the article implicitly endorses while also insisting on the active, practical character of cognition.

Trotsky, In Defence of Marxism — particularly the essays on dialectical materialism and the relationship between Marxism and the natural sciences, which share the article's insistence on the unity of the dialectic across nature and society.

Alan Woods, The History of Philosophy — the broader series from which this article is drawn, which traces the development of materialism from the ancient Greeks through to Marx and Engels.

IDOM articles on commodity fetishism — which show how the philosophical themes of alienation and the domination of people by things are concretised in Marx's critique of political economy.
