Preface to the new edition of Engels Dialectics of Nature

Marxist Theory · 2026-05-13

Core Argument¶

This preface argues that Engels' Dialectics of Nature remains a fundamentally valid work, not despite the obsolescence of its specific scientific data, but because its core method — the discovery of dialectical laws within nature itself, rather than their imposition upon it — has been repeatedly confirmed by subsequent scientific developments. The central claim is that dialectical materialism is not a philosophical framework applied externally to science, but the philosophical expression of how nature actually works: through interconnection, contradiction, qualitative leaps, and the unity of opposites. The most advanced contemporary science — from complexity theory and punctuated equilibria to ubiquity theory and non-equilibrium physics — is, often unwittingly, rediscovering the dialectical categories Engels articulated over a century ago. The preface therefore positions the republication of Engels' text as a weapon in the struggle against both religious obscurantism (creationism, intelligent design) and the idealist mysticism that has crept into cosmology and theoretical physics.

Theoretical Grounding¶

The analysis draws on Engels' own distinction between imposing dialectics on nature and discovering it in nature — a methodological point that grounds dialectical materialism in objective reality rather than subjective idealism. The key laws invoked are the transformation of quantity into quality, the interpenetration of opposites, the negation of the negation, and the spiral form of development. These are presented not as a priori categories but as generalisations from the actual behaviour of matter in motion.

The preface situates itself within the classical Marxist tradition that runs from Engels through Lenin's Materialism and Empirio-criticism to the contemporary work of Alan Woods and Ted Grant's Reason in Revolt. It draws heavily on the Hegelian categories of essence and appearance, necessity and accident, freedom and necessity — but always in their materialist form, where freedom is understood as the knowledge of natural necessity and the consequent ability to make those laws work for humanity. The argument also engages with the dialectical biology of Levins and Lewontin and the evolutionary theory of Gould and Eldredge, showing how non-Marxist scientists have arrived at dialectical conclusions through empirical research.

Conjunctural Relevance¶

The preface is written in 2006, a moment when the George W. Bush administration had openly embraced intelligent design, and the Catholic Church had appropriated the Big Bang as evidence for creation. The conjuncture is defined by a dual offensive: the political offensive of Christian fundamentalism masquerading as science, and the ideological retreat within sections of the scientific community itself toward mysticism (Hawking's "mind of God", Davies' "mystical path", Prigogine's "God of Genesis"). Against this, the preface argues that the most advanced scientific developments — particularly ubiquity theory, non-equilibrium physics, and complexity theory — are moving toward dialectical materialism, not away from it. The "critical state universality" discovered by physicists, in which the specific properties of particles become irrelevant and only the general shape of organisation matters, is presented as a direct confirmation of Engels' conception of dialectics as the "science of interconnections."

The economic conjuncture is addressed only obliquely, through Engels' closing remarks on the contradiction between expanded productive capacity and the misery of the masses — a contradiction that, in 2006, was approaching the conditions that would erupt in the 2008 crisis. The preface's real conjunctural intervention is epistemological: it insists that the struggle for a correct scientific method is inseparable from the political struggle for socialism.

Where the Argument Continues¶

The preface explicitly directs readers to Alan Woods and Ted Grant's Reason in Revolt as the modern counterpart to Dialectics of Nature, providing an up-to-date analysis of chaos theory and complexity theory from a Marxist standpoint. The argument about the relationship between necessity and freedom, and the leap from the realm of necessity to the realm of freedom, is developed at length in Engels' Anti-Dühring and Socialism: Utopian and Scientific. The treatment of the labour theory of human evolution connects to Engels' essay "The Part Played by Labour in the Transition from Ape to Man," which is included in the Dialectics of Nature volume itself.

The preface does not develop the political implications of its scientific argument — how the dialectical understanding of nature relates to the strategy and tactics of the revolutionary party, or how the critique of gradualism in nature connects to the critique of reformism in politics. These connections are made elsewhere in the IDOM corpus, particularly in articles on the dialectics of revolution and the critique of evolutionary socialism. The relationship between scientific discovery and class consciousness — why it is that bourgeois science systematically resists dialectical conclusions — is gestured at but not fully theorised here.

Hegel, The Doctrine of Essence — the idealist source of the categories Engels materialises

Key Quotes¶

"To me there could be no question of building up the laws of dialectics into nature, but of discovering them in it and evolving them from it."
"The general nature of dialectics to be developed as a science of interconnections, in contrast to metaphysics."
"The great basic thought that the world is to be comprehended not as a complex of ready-made things but as a complex of processes, in which apparently stable things no less than the concepts, their mental reflections in our heads, go through an uninterrupted change of coming into being and passing away."
"All equilibrium is only relative and temporary."
"Necessity has been defined, and rightly so, as the union of possibility and actuality."
"Only conscious organisation of social production, in which production and distribution are carried on in a planned way, can lift mankind above the rest of the animal world as regards the social aspect, in the same way that production in general has done this for mankind in the specific biological aspect."
