Marxism-Leninism insists that science begins where immediate appearance is no longer taken as the truth of things. The world first presents itself to us in forms that are visible, concrete and often misleading. But if form and essence directly coincided, there would be no need for theory, no need for political economy, and no need for revolutionary analysis. The task of communist theory is therefore to move from what appears on the surface to the internal relations that generate that appearance. Form is the way that essence appears, develops and becomes visible, though never in a complete or transparent way. Essence is not something mystical hidden behind reality, but the real inner connection, lawfulness and necessity of a phenomenon; essence lies not outside but inside its concrete manifestations, and scientific knowledge advances by moving from phenomenon to deeper and deeper levels of essence.
For this reason, Marxism-Leninism also rejects both crude mechanicism and abstract idealism. On the one hand, it rejects the empiricist error of treating immediate facts as self-explanatory, as though what lies on the surface were the whole truth. On the other hand, it rejects the metaphysical error of treating essence as a fixed abstraction detached from history, contradiction and change. Essence develops. It becomes concrete through forms, and these forms can lag behind, mediate, distort, or even temporarily obstruct the development of the content they express. Form is thus not passive. It is an active moment of the content itself. But the leading role remains with content: content generates form, and when the old form becomes a fetter, contradiction sharpens until a new form emerges. This is why Marxism studies not only what something is “in essence”, but how that essence is historically realised, modified and fought out in concrete circumstances. This is also why the categories of form and essence are inseparable from class struggle.
This clarification is decisive because bourgeois ideology lives precisely on the confusion of form and essence. Under capitalism, social relations between classes appear as relations between things: commodities seem to possess value naturally, money seems to generate more money by itself, profit appears as the reward of enterprise, and wages appear as payment for labour rather than the price of labour-power. In the same way, bourgeois ideology mystifies imperialism, which is not presented in its essence as a determinate social and economic relation rooted in the development of capitalism, but instead appears as a merely political relation between states, governments, blocs, or peoples. A state may call itself socialist, anti-imperialist, democratic or national-liberationist; a war may appear as defence, sovereignty or civilisation; a bloc may present itself as weak or progressive. None of this can be judged at the level of declarations, symbols or diplomatic posture alone. The question is always: what social relations, what class interests, what patterns of accumulation, and what place in the wider reproduction of capitalism do these forms express? Marxism-Leninism therefore treats form seriously, but refuses to worship it.
This distinction becomes indispensable in analysing imperialism. Imperialism does not appear only in the most obvious forms – invasion, occupation, colonisation, sanctions, or the open diktat of the strongest powers. Those are important forms, but they do not exhaust the essence. The essence of imperialism lies in the global organisation of capitalism at its monopoly stage: unequal development, the export of capital, the struggle for profitable spheres of accumulation, and the shifting hierarchy of mutual dependencies and domination among capitalist states. To identify imperialism only with the most aggressive or most visible states is to mistake one form of the system for its whole content. Imperialism is not merely what the system looks like at its most concentrated points; it is the world structure that produces those appearances in the first place.
Section 4 of Tracing the Chain is valuable precisely because it applies this method against two widespread confusions between form and essence. The first error is to say that China or Russia cannot be imperialist because their form still carries residues of socialist language, state ownership, or conflict with the West. The decisive question is not the form of the state, but its economic essence: capitalist relations of production, the emergence of a bourgeoisie, outward investment, monopolies, and the drive to reshape the world market in its own favour. If analysed on the basis of objective and concrete economic metrics, China and Russia are simply imperialist states operating within the same global logic of capitalist accumulation and imperialist competition. The second error is to say that the United States alone is imperialist because, at the level of immediate appearance, it remains the dominant military power. It is true that the US sits at the apex of this hierarchy and gives the most concentrated expression of imperialist domination today. But if we stop there, we mistake the highest and clearest form for the whole essence. The deeper essence is an imperialist world system in which different capitalist states occupy different positions, combine dependence with domination in different proportions, and clash according to the same underlying logic of accumulation. Thus US militarism is not imperialism itself, but the most powerful expression of a wider imperialist totality; and China is not outside that totality simply because its imperialist character appears in a different form.
From this follows a necessary political conclusion. Communists must not let themselves be governed by appearances – neither the appearance of anti-imperialism in one bourgeois camp, nor the appearance of a single enemy in another. The task is to grasp the essence beneath the forms: the imperialist system as a whole, the place of each bourgeoisie within it, and the independent interests of the international working class against them all. Only then can anti-imperialism be rescued from opportunism and restored to its proper content – proletarian struggle against the entire capitalist order.
