Classics The Three Sources and Three Component Parts of Marxism

Marxist Theory · 2026-05-13

Core Argument¶

Lenin's central thesis is that Marxism is not a sectarian doctrine but the direct and legitimate successor of the highest achievements of nineteenth-century thought. The article argues that Marxism is "omnipotent because it is true" — not because it emerged in isolation, but because it systematically answered questions that the most advanced minds of humanity had already posed. Marxism's power lies in its completeness: it provides an "integral world conception" that is irreconcilable with superstition, reaction, or bourgeois oppression precisely because it synthesises German philosophy, English political economy, and French socialism into a unified theoretical weapon for the working class.

The claim is that Marxism's three component parts are not merely historical influences but living elements of a single, coherent doctrine. Philosophical materialism provides the method; the labour theory of value and the doctrine of surplus value provide the economic analysis; and the theory of class struggle provides the strategic conclusion. Each component is necessary, and together they form a whole that is greater than the sum of its parts.

Theoretical Grounding¶

Lenin grounds his argument in the classical Marxist tradition as developed by Marx and Engels, drawing explicitly on Engels' Ludwig Feuerbach and Anti-Dühring, as well as the Communist Manifesto. The article situates itself within the materialist conception of history: political institutions are a superstructure on the economic foundation, and social knowledge reflects the economic system of society. Lenin emphasises that Marx did not simply adopt eighteenth-century materialism but enriched it with Hegelian dialectics — the "doctrine of development in its fullest and deepest forms" — producing a materialism that extends from nature to human society.

The economic analysis rests on the labour theory of value as developed by Smith and Ricardo but completed by Marx. Lenin identifies the doctrine of surplus value as "the cornerstone of Marx's economic theory," revealing that beneath the apparent relation of things (commodity exchange) lies a relation of men — the exploitation of wage labour by capital. This is a direct continuation of Marx's critique of political economy in Capital.

The political conclusion — the doctrine of the class struggle — is presented as the necessary deduction from historical materialism and the experience of the bourgeois revolutions. Lenin insists that only by discovering the class interests behind all moral, religious, and political phrases can the working class avoid being "the stupid victims of deceit and self-deceit in politics."

Conjunctural Relevance¶

Written in March 1913, the article addresses a specific conjuncture: the period of relative capitalist stabilisation before the First World War, when reformism and opportunism were gaining ground within the workers' movement. Lenin is countering the claim — widespread among bourgeois academics and reformist socialists alike — that Marxism is a "pernicious sect" or a "hidebound, petrified doctrine." He is defending the revolutionary core of Marxism against those who would dilute it into a doctrine of gradual reform within capitalism.

The article also responds to the latest discoveries in natural science — "radium, electrons, the transmutation of elements" — which bourgeois philosophers were using to revive idealist and religious interpretations of the world. Lenin insists that these discoveries confirm rather than refute dialectical materialism, anticipating his later polemic in Materialism and Empirio-Criticism.

Geopolitically, the article notes that "capitalism has triumphed all over the world" and that "independent organisations of the proletariat are multiplying all over the world, from America to Japan and from Sweden to South Africa." This is a moment of capitalist globalisation and the simultaneous spread of working-class organisation — a conjuncture that demands a unified, internationalist theoretical orientation.

Where the Argument Continues¶

This article is a condensed summary of positions Lenin develops at greater length elsewhere. The philosophical argument is expanded in Materialism and Empirio-Criticism (1909), where Lenin defends dialectical materialism against the Machist and idealist currents within Russian Social Democracy. The economic argument is a compressed version of the analysis in Capital and Lenin's own The Development of Capitalism in Russia (1899). The political conclusion — the necessity of independent working-class organisation and the rejection of reformism — is developed in What Is To Be Done? (1902) and The State and Revolution (1917).

Within the IDOM corpus, this article functions as a foundational text, often cited in discussions of Marxist method and the relationship between theory and practice. It is regularly referenced in articles defending the revolutionary character of Marxism against reformist and centrist distortions, and in educational materials on the ABC of Marxism.

Connections¶

This article should be read alongside:

Engels, Ludwig Feuerbach and the End of Classical German Philosophy — the key text on the relationship between Marxism and its philosophical predecessors.
Engels, Anti-Dühring — the systematic exposition of the Marxist world outlook.
Marx, Capital, Volume I — especially the chapters on commodity fetishism and surplus value.
Lenin, Materialism and Empirio-Criticism — the defence of dialectical materialism against idealist currents.
Lenin, What Is To Be Done? — the argument for the necessity of revolutionary theory and independent working-class organisation.
Trotsky, In Defence of Marxism — the later defence of dialectical materialism against petty-bourgeois revisionism.

The article also connects to the broader Marxist tradition's insistence on the unity of theory and practice, and to the polemic against "vulgar Marxism" that reduces Marxism to economic determinism while discarding its dialectical and revolutionary content.

Key Quotes¶

"The Marxian doctrine is omnipotent because it is true. It is complete and harmonious, and provides men with an integral world conception which is irreconcilable with any form of superstition, reaction, or defense of bourgeois oppression."
"Marx's philosophy is matured philosophical materialism, which has provided humanity, and especially the working class, with powerful instruments of knowledge."
"Where the bourgeois economists saw a relation of things (the exchange of one commodity for another), Marx revealed a relation of men."
"The doctrine of surplus value is the cornerstone of Marx's economic theory."
"People always were and always will be the stupid victims of deceit and self-deceit in politics until they learn to discover the interests of some class behind all moral, religious, political and social phrases, declarations and promises."
"Marx's philosophical materialism has alone shown the proletariat the way out of the spiritual slavery in which all oppressed classes have hitherto languished. Marx's economic theory has alone explained the true position of the proletariat in the general system of capitalism."
