Classics Preface to A Contribution to the Critique of Political Economy

Marxist Theory · 2026-05-13

Core Argument¶

This is not an argument in the conventional sense but the canonical statement of the materialist conception of history. Marx's central claim is that the legal and political superstructure of any society, together with the forms of social consciousness that accompany it, arises from and is conditioned by the economic base — the totality of relations of production corresponding to a given stage of development of the material productive forces. The motor of historical change is the contradiction that emerges when the productive forces outgrow the property relations within which they have developed, turning those relations from forms of development into fetters. At that point an epoch of social revolution begins, and the entire immense superstructure is transformed, sooner or later.

Marx is also making a methodological claim: that the anatomy of civil society is to be sought in political economy, and that the task of the critic is to explain consciousness from the contradictions of material life, not the reverse. The preface is thus both a summary of a lifetime's research and a declaration of intellectual rupture with the Hegelian and idealist traditions from which Marx emerged.

Theoretical Grounding¶

The preface is the foundational text of historical materialism. It establishes the base-superstructure model that has been central to Marxist theory ever since, though it is often crudely rendered by later writers. Marx is careful to specify that the economic structure is the real foundation on which arises a legal and political superstructure, and to which correspond definite forms of social consciousness — not a mechanical determinism but a conditioning relation.

The concept of contradiction between forces and relations of production is the theoretical engine of the whole framework. Marx identifies successive modes of production — Asiatic, ancient, feudal, modern bourgeois — as epochs of economic development, and declares the bourgeois mode to be the last antagonistic form of the social process of production, creating within itself the material conditions for its own supersession. This is the theoretical basis for the revolutionary conclusion of the Communist Manifesto: that capitalism produces its own gravediggers.

The preface also situates Marx's work in relation to Hegel, from whom he takes the concept of civil society but inverts the idealist method, and to the classical political economists whose categories he will critique. The debt to Engels is acknowledged explicitly: they arrived at the same conclusion by different routes, and the German Ideology manuscript — abandoned to the "gnawing criticism of the mice" — was their first attempt to settle accounts with their philosophical past.

Conjunctural Relevance¶

The preface is not a conjunctural analysis but the theoretical framework for all conjunctural analysis. Its relevance to the present moment lies in the question it poses: have the productive forces of contemporary capitalism — automation, artificial intelligence, global supply chains, digital platforms — come into conflict with the existing relations of production, specifically the private ownership of the means of production and the wage-labour relation? The stagnation of real wages, the growth of precarious employment, the crisis of housing affordability, and the concentration of wealth in a shrinking fraction of the population all suggest that the fetters are tightening.

The preface also provides the theoretical basis for understanding why reformism fails: no social order is ever destroyed before all the productive forces for which it is sufficient have been developed, and new relations of production do not replace older ones before the material conditions for their existence have matured within the old society. This is not a fatalistic waiting game but a call to identify those material conditions as they ripen and to intervene consciously in the class struggle. The current conjuncture — with its overlapping crises of climate, war, and pandemic — is precisely the kind of epoch of social revolution Marx describes, in which the ideological forms (nationalism, populism, identitarian politics) must be explained from the contradictions of material life.

Where the Argument Continues¶

The preface is a summary, not a finished argument. It points forward to Capital, which Marx describes as the substantiation of the results anticipated here. The reader who wishes to follow Marx must "advance from the particular to the general" — that is, from the analysis of the commodity to the theory of the capitalist mode of production as a whole.

The argument continues in several directions within the Marxist.com corpus:

The Communist Manifesto (also available on the site) develops the political conclusions of the materialist conception of history, identifying the proletariat as the class destined to overthrow bourgeois society.
Engels's Socialism: Utopian and Scientific elaborates the theoretical framework of historical materialism for a popular audience.
The IDOM article "The Materialist Conception of History" provides a contemporary exposition and defence of the theory against its critics.
The Grundrisse introduction, which Marx omitted from this preface, is available on the site and contains the methodological reflections on the relationship between production, distribution, exchange, and consumption that underpin the whole project.
Engels's later preface to the Communist Manifesto (1888) and his Origin of the Family, Private Property, and the State address the modification of the Asiatic mode of production thesis noted in the footnote.

Connections¶

Hegel, Philosophy of Right: Marx's critical re-examination of Hegel's philosophy of law was the starting point for his materialist turn. The concept of "civil society" is taken from Hegel but given a materialist foundation.
Engels, The Condition of the Working Class in England: The work that brought Engels to the same conclusions as Marx by a different route — empirical observation of the industrial proletariat.
Marx, The German Ideology: The abandoned manuscript that first set out the materialist conception of history in full, though it remained unpublished in Marx's lifetime.
Marx, The Poverty of Philosophy: The polemic against Proudhon that first outlined the materialist conception in published form.
Marx, Capital, Volume I: The substantiation of the results announced in the preface, beginning with the analysis of the commodity.
Engels, The Origin of the Family, Private Property, and the State: The application of the materialist method to pre-class societies, incorporating Morgan's discoveries about the gens and the tribe.
Plekhanov, The Development of the Monist View of History: A classic exposition of historical materialism that defends it against both idealist and mechanical-materialist distortions.

Key Quotes¶

"In the social production of their existence, men inevitably enter into definite relations, which are independent of their will, namely relations of production appropriate to a given stage in the development of their material forces of production."
"It is not the consciousness of men that determines their existence, but their social existence that determines their consciousness."
"At a certain stage of development, the material productive forces of society come into conflict with the existing relations of production or – this merely expresses the same thing in legal terms – with the property relations within which they have operated hitherto. From forms of development of the productive forces these relations turn into their fetters. Then begins an era of social revolution."
"No social order is ever destroyed before all the productive forces for which it is sufficient have been developed, and new superior relations of production never replace older ones before the material conditions for their existence have matured within the framework of the old society."
"Mankind thus inevitably sets itself only such tasks as it is able to solve, since closer examination will always show that the problem itself arises only when the material conditions for its solution are already present or at least in the course of formation."
"The bourgeois mode of production is the last antagonistic form of the social process of production – antagonistic not in the sense of individual antagonism but of an antagonism that emanates from the individuals' social conditions of existence – but the productive forces developing within bourgeois society create also the material conditions for a solution of this antagonism."
