Commentary on the Logic, Chapter 14
The New Level: Constitutive Relation
A preliminary remark from Hegel, which explains why this chapter stands on its own at all: chemism is “a category of objectivity which is not usually singled out but is lumped together with mechanism” — under the common name of mechanical relation (Encyclopedia Vol. 1, § 200 Addition). The distinction is aimed precisely against this conflation. Whoever throws the two together loses the difference between a relation that leaves things untouched and one that makes them what they are.
In chemism, A is what it is only through B. What an acid is shows itself in a determinate reactive relation — not in the fact that a base happens to be present, but in the fact that the determination cannot be stated without reference to a counterpart. The difference is not a matter of indifference; it is constitutive. The three marks:
| Concept | Meaning | Example |
|---|---|---|
| Affinity | Tendency toward combination | Acid “seeks” base |
| Constitutive relation | Relation belongs to the essence | No acid without base |
| Qualitative transformation | Combination gives rise to something new | Salt is not “acid plus base” |
Heinrichs’ dual perspective — system and enactment: Every chemical (and every higher) structure manifests itself doubly:
| As system | As enactment |
|---|---|
| Ecosystem, market, language | Eating/being eaten, exchange, conversation |
| The institution “university” | The concrete 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 maintain themselves). The answer: both are ways of manifesting the same structures — not opposites, but complementary perspectives. The system is no more cold than the enactment, nor is the enactment more true 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 completion by the other.
| Level | Examples | Characteristic |
|---|---|---|
| Inanimate nature | acid/base, north pole/south pole, particle/antiparticle | Polarity, existing only in pairs |
| Life | organs (heart–lung–circulation), sexes, predator/prey | Functional relatedness |
| Spirit | father/child, buyer/seller, doctor/patient | Constitutive roles — existing only in pairs |
Stekeler’s insight: Chemism is the logic of personal roles.[1] “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 holds 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), and the neutral product (something qualitatively new).
Work through this: Why doesn’t salt taste like sodium? Sodium (toxic) + chlorine (toxic) → 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 its parts but something qualitatively different.
| Level | Examples | Characteristic |
|---|---|---|
| Inanimate nature | Acid-base reaction, alloying, combustion | Qualitative transformation |
| Life | Metabolism, mating, brood care | Assimilation, reproduction |
| Spirit | Genuine dialogue, argumentative synthesis, diplomatic compromise | A new understanding arises that no one held before |
Correvon 1824 records what separates chemism from mechanism, and it is a determination belonging to the logic of essence: “In chemism, the moments are posited, as an independent totality, as at the same time capable of being a non-independent totality; thus it is the posited contradiction that in mechanism was only in itself.”[2]
In mechanism, the contradiction was present but hidden: the bodies are independent and yet connected, without this connection mattering to them. In chemism, the same contradiction is posited — acid and base are what they are only through their opposite, and they perish through it. This is why chemism is not merely a richer relation but the truth of the poorer one, come to appearance.
The Deficiency of Chemism — The Product Is Dead
Neutralization is at once fulfillment and annihilation 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 perished. 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. Hegel determines the product more precisely, and this determination is better than the word “dead”: it “is indeed in conformity with the concept, but the animating principle of differentiation does not exist in it, since this principle has sunk back into immediacy; the neutral is therefore something separable” (Encyclopedia, vol. 1, § 202). The salt is not dead matter but separable — it holds together only as long as nothing attacks it, because it lacks what would hold it together.
The transition: The text has so far said that the system lacks an organizing principle. That is correct, but it is a description in terms of deficiency — whereas Hegel’s ground is positive. Both chemical processes, the reduction of the differentiated to the neutral and the differentiation of the neutral, “show their finitude in passing over into products in which they are sublated.” Conversely, the process proves the presupposed immediacy of the objects to be null. And from this follows: “Through this negation of the externality and immediacy into which the concept as object was submerged, it is posited as free and for itself against that externality and immediacy — as purpose” (§ 203).
Julie Maybee describes the same step from the standpoint of function, and this makes it vivid: in chemism the unity of the moments emerges — but only as concept, not yet as object. The neutral product is the first case in which this unity accomplishes both of the things it must accomplish: articulating and holding together.[3]
The purpose, then, does not arise because something is missing, but because the concept steps out of its submersion — it was, in mechanism and chemism, entirely absorbed into the objects, and as their independence proves itself to be null, the concept is once again for itself. Here Kehler’s criterion applies: there was “too much identity,” and the identity dissolves.
Deepening: The Spiral Structure
Already in the chapter on Measure (Chapter 3), Hegel used chemical concepts — affinity, neutralization, elective affinity — whose systematic place is only here. Is that 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 implicitly performed. 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 implicit->explicit is the movement of comprehension itself.
Counter-check on the following example: One reservation up front. Hegel’s chemism was developed on the chemistry of his time — acid and base, affinity, elective affinity. Present-day chemistry explains this through electron configurations and describes nothing that would of itself be directed toward an other. Anyone who introduces modern examples must therefore show that the logical structure holds independently of the outdated physics. [KF]
Stekeler-Weithofer objects to this, and his objection is stronger than the suspicion: even after the development of modern atomic theory, he holds, there is “absolutely no good reason to believe in a full mechanizability of the processes of chemistry, electromagnetism, and the electrodynamics only later fully developed by Maxwell, which Hegel brings under the heading of chemism.”[4] And for the next stage: biology, in its forms of representation and explanation, “necessarily relies on given teleological forms of autopoietic self-preservation.”
Thus the sequence is not superseded but still at work in the sciences: physics describes mechanically, chemistry cannot get by with that alone, biology needs forms of purpose. What Hegel develops as a logical gradation reappears as a division of labor among the natural sciences — and the attempt at reduction, to trace everything back to the first stage, has remained the point of contention, not the settled result.
DNA as a Paradigmatic Example
Structural parallel, not a scientific proof: DNA displays chemism in its purest form: adenine pairs with thymine, guanine with cytosine — in RNA, uracil takes thymine’s place. The pairing is highly specific, but it is a bonding relation, not a recognition; mismatches occur and are repaired. The relation is highly specific and constitutive — the DNA strands exist for one another, each being the complement of the other. Out of this specificity, information arises. The philosophical point: the relation itself becomes substance. DNA is neither purely chemical nor purely mechanical — it shows the transition to teleology: the information organizes subsequent processes (protein synthesis), and thus already has the character of an inner purpose. But this is not yet teleology in the logical sense: the structure acts without a purpose being set over against a material. Consciousness does not decide this — the step to teleology requires the separation of purpose and material, which is precisely what is missing here (cf. 16.1).
Modern application: interfaces as technical chemism. These chemical principles find perhaps 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 to each other. Incompatible ports simply do not react with one another. An adapter functions like a catalyst: it enables the connection without being consumed itself. And when two computer systems are joined via compatible interfaces, network capability emerges — a qualitatively new property contained in neither of the individual systems. Chemical principles (qualitative affinity, catalytic mediation, emergent novelty) operate far beyond chemistry. 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 to teleology.
