Core Argument¶
Engels' Dialectics of Nature represents an ambitious but unfinished attempt to discover dialectical laws operating within natural processes, rather than imposing them from without. Compiled posthumously from his notes and published in 1925, the work remained incomplete because Engels' political duties—particularly writing Anti-Dühring and editing Das Kapital after Marx's death—consumed the time he had intended for this comprehensive study of science and dialectical materialism. Despite much of the scientific data now being obsolete, with cosmology, time spans and terminology superseded, the general method retains its validity.
The core argument holds that natural processes confirm dialectical laws of change across matter, motion and interconnection. Engels' essay on labour in ape-to-human evolution has received particular praise from Stephen Jay Gould for its prescient argument concerning gene-culture co-evolution. Modern science has converged with dialectical concepts in remarkable ways: chaos theory, complexity theory and punctuated equilibria all engage with non-equilibrium, phase transitions, interconnection and development through contradiction. Levins and Lewontin's The Dialectical Biologist explicitly builds on Engels, arguing that persistence requires explanation through opposing forces and that systems constitute networks of positive and negative feedbacks.
Engels criticises the scientific establishment's metaphysics for treating chance and necessity as separate categories. Following Hegel, he argues that the accidental has a cause yet also has no cause; necessity is inseparably linked to accident and expresses itself through it. This method enabled Darwin to discover that infinite accidental differences between individuals compelled him to question the metaphysical rigidity of the species concept. Buchanan's Ubiquity extends this logic of critical states from physical systems to human history, arguing that understanding mass movements requires grasping the character of the critical state, because patterns emerge from millions of individual actions.
The dialectical conception of freedom is central: freedom consists not in independence from natural laws but in knowledge of them, allowing them to work for us. For Marx, shortening the working day was a precondition for freedom; for Engels, socialism meant the leap from the Realm of Necessity to the Realm of Freedom. Scientists have accidentally discovered a dialectical, non-linear view of nature, opening new possibilities that cut against attempts to reconcile science with religion. The republication of Dialectics of Nature provides philosophical weapons against religious obscurantism and arms a new generation with dialectical materialism—a precondition for changing the world.
