Trotsky’s Notebooks: Excerpts on Lenin, Dialectics, and Evolutionism

Core Argument

In his notebooks, Trotsky elaborates a materialist dialectic conceived as the logic of motion, development, and evolution, standing in relation to formal logic as higher mathematics stands to lower. Where formal logic treats concepts as fixed—a equals a—dialectics holds that a does not equal a over time, because reality is ceaselessly in flux. The fundamental law of dialectics is the transition of quantity into quality, which Trotsky presents as the general formula for all evolutionary processes in nature and society. This law underpins Darwinism, Marxism, and philosophical materialism, and it demolishes the notion of absolute moral values by demonstrating how quantitative economic changes prepare radical qualitative shifts in ethical criteria. Trotsky criticises Hegel for failing to grant this law its proper primacy, a failure rooted in Hegel’s ignorance of Darwin and Marx. Anglo-Saxon empiricism, meanwhile, resists dialectics by maintaining impermeable bulkheads between incompatible categories, such as Darwin and the Bible.

The conversion of abstract possibility into concrete necessity is another key dialectical law, ultimately reducible to the transition of quantity into quality. Catastrophes occur when quantitative changes conflict with congealed forms, leading either to the old form’s victory or to its explosion and replacement. Trotsky contrasts Lenin’s dialectic, which operates with living classes on a massive scale, with Martov’s, which remains limited to derivative processes and episodic changes within the intelligentsia milieu. Lenin’s thought simplified reality to grasp the basic factors, proving its power in periods of profound upheaval; Martov’s dialectic became a screen for uncertainty and yielded mistakes to the right.

The materialist dialectic is a differentiated unity, not an arbitrary combination of terms, and serves as the scientific foundation for human praxis. It overcomes the fetters of static concepts by revealing their relativity and transitions. Human reason, nature’s youngest child, developed from vulgar logic to dialectics through accumulated scientific experience, spurred by historical class development—a lineage traceable to after the Great French Revolution. Cognition splits nature into fixed categories, contradicting reality; dialectics gradually overcomes this contradiction. Subjective dialectics is a distinctive part of objective dialectics, possessing its own forms and regularities. Consciousness enjoys autonomy from physiological processes, able to influence the body through its own logical laws. The psyche, arising from matter, is freed from material determinism to independently influence matter. The syllogism is dialectical thinking’s fundamental cell. Teleology is a special department of determinism. Evolution permits no bargains: it must be admitted or rejected.
