Commentary on the Logic, Chapter 14

The New Stage: Constitutive Relation

In chemism, A is only what it is through B. Acid is only acid in relation to base. The difference is not incidental but constitutive. The three markers:

Concept Meaning Example
Affinity Tendency toward combination Acid “seeks” base
Constitutive relation The relation belongs to the essence No acid without base
Qualitative transformation Combination produces something new Salt is not “acid plus base”

Heinrichs’ dual perspective — system and enactment: Every chemical (and every higher-order) structure manifests itself twofold:

As system As enactment
Ecosystem, market, language Eating/being eaten, exchange, conversation
The institution “university” The particular lecture
Grammar The speech act

This distinction resolves a classic dispute in social philosophy. Some emphasize enactment (how people act with one another), others the system (how institutions sustain themselves). The answer: both are modes of manifestation of the same structures — not opposites, but complementary perspectives. The system is no “colder” than the enactment, nor is the enactment “truer” than the system.

The Chemical Object — The Differentiated Terms

The “differentiated terms” are one-sided extremes that are related to one another. Each is “incomplete,” dependent on complementation.

Level Examples Characteristic
Inanimate nature acid/base, north pole/south pole, particle/antiparticle polarity, existing only in pairs
Life organs (heart–lungs–circulation), sexes, predator/prey functional interrelation
Spirit father/child, buyer/seller, doctor/patient constitutive roles — existing only in pairs

Stekeler’s insight: Chemism is the logic of personal roles. “The person constitutes itself through its relations to other persons.” I am a father only through my child. The teacher exists only through the students. Whoever understands this has a fundamental critique of methodological individualism: persons are not isolated atoms that subsequently enter into relations, but are constituted through relations.

The Chemical Process — Neutralization and Emergence

Three moments: the one-sided extremes (the differents before the reaction), the process of neutralization (the transformation itself), the neutral product (the qualitatively new).

Carry this through: Why doesn’t salt taste like sodium? Sodium (poisonous) + chlorine (poisonous) → table salt (edible, essential to life). The atoms are still there, but their properties have vanished — sublation in its purest form. The whole is not the “sum of the parts,” but something qualitatively different.

Level Examples Characteristic
Inanimate nature Acid-base reaction, alloy, combustion Qualitative transformation
Life Metabolism, mating, brood care Assimilation, reproduction
Spirit Genuine dialogue, argumentative synthesis, diplomatic compromise A new understanding arises that no one had before

The Deficiency of Chemism — The Product Is Dead

Neutralization is at once fulfillment and destruction of the differentiated terms. The acid finds its base — and ceases to be an acid. The product is a dead unity: the living tension has collapsed. The salt has “become indifferent” — a relapse into mechanism! The system constantly requires an external supply of energy and new differentiated terms to keep the process going. Enzymes as catalysts point toward the limit here: they mediate reactions without being consumed — but the system still lacks an organizing principle that would order these processes toward a goal.

Deepening: The Spiral Structure

Already in the chapter on Measure (Chapter 3), Hegel used chemical concepts — affinity, neutralization, elective affinity — whose systematic place lies only here. Is this a circle? The spiral structure resolves the problem: (1) First turn (Measure): We experience the structure of affinity — in implicit reflection. We use chemical concepts without knowing their systematic place. (2) Second turn (Essence): We reflect on the structures of mediation — recognizing that relations can be constitutive. (3) Third turn (Chemism): We comprehend systematically what we had at first only performed implicitly. The “later” was already at work in the “earlier” — but not as an error, rather as an expression of the basic structure of all thinking: the spiral from implicit to explicit is the movement of comprehension itself.

DNA as a Paradigmatic Example

A structural parallel, not a scientific proof: DNA displays chemism in its purest form: adenine “recognizes” only thymine, guanine only cytosine. The relationship is highly specific and constitutive — the DNA strands exist for one another, each being the complement of the other. Out of this specificity arises information. The philosophical point: the relationship itself becomes substance. DNA is neither merely “chemical” nor merely “mechanical” — it shows the transition toward teleology: information organizes subsequent processes (protein synthesis), and thus already has the character of an inner purpose. But DNA “wants” nothing — it is blind. The full transition to teleology requires conscious purpose-setting.

A modern application: interfaces as technical chemism. These chemical principles perhaps find their most vivid illustration in information technology: USB-A and USB-B exist for one another like acid and base — they have a specific affinity toward each other. Incompatible connectors simply “do not react” with one another. An adapter functions like a catalyst: it enables the connection without itself being consumed. And when two computer systems are linked through compatible interfaces, network capability emerges — a qualitatively new property that was contained in neither individual system. Chemical principles (qualitative affinity, catalytic mediation, emergent novelty) operate far beyond chemistry itself. At the same time, both DNA and interfaces show why chemism cannot be the last word: both point toward purposes — but where do these purposes come from? This leads us to teleology.
