Commentary on the Logic, Chapter 7
Actuality as the Unity of Inner and Outer
Actuality is more than mere being (the logic of being) or existence (the logic of appearance). Actuality is what acts — from “to act” (wirken, to work or produce an effect). A shadow exists, but it is hardly actual. An error exists, but it has no lasting actuality. Actuality is the unity of essence and existence: something is actual when, for an inner reason, it must necessarily be so.
Possibility and Necessity
Formal possibility: “Everything is possible that does not contradict itself.” Empty of content. Hegel’s critique: “There is therefore no emptier talk than that of such possibility.” The less someone knows, the more they consider possible — that is why children have a “great imagination”: not because they are especially creative, but because they do not yet know the obstacles. The reverse holds too: the more we know about the world, the more “impossibilities” we know — this is not a loss but a gain in the sense of reality. But beware: Peter Ustinov warned that in old age one knows so much — “including a great many things that are not so.” The old can “know” things that are no longer true. Paradigm shifts call into question the axioms of the previous explanatory pattern — what counted as “impossible” yesterday is reality today. The sociology-of-science insight (Planck/Kuhn): the new often only prevails once the adherents of the old have died off. This corresponds to the S³ structure of life (Chapter 19): self-differentiation — knowledge divides into schools and paradigms; self-preservation — each paradigm reproduces itself through training and institutions; self-sublation — the individual scientist dies, but science renews itself precisely through this. The “mortality” of scientists is not merely a regrettable circumstance but a condition of the possibility of paradigm shifts.
Real possibility: This asks about concrete conditions. An acorn has DNA plus cellular machinery (ground), and needs soil, water, light (conditions). When all conditions are fully present, the thing comes into existence — not as a checklist to be ticked off, but as a system that closes. Then it must occur.
Try this yourself: Think of an insight that “closed” for you — an aha-moment where everything fit together. What was the moment of closure? Was it the addition of one final piece of evidence — or the closing of an entire web of connections, in which the pieces of evidence suddenly supported one another? Precisely this closing is the flip from “probably true” to “must be so”.
Contingency as transition. Between possibility and necessity stands a category that is easily skipped over, and without which the transition does not follow.
Something that is possible and becomes actual, without it being possible to state why it and not the opposite, is called contingent. The contingent is the unity of possibility and actuality in its immediate form: it is, but it could also not be.
The point is that this determination sublates itself. For the contingent is not groundless — it has conditions, and where all conditions are present, it occurs necessarily. Contingent, then, does not mean: without ground. It means: the ground lies outside what is being considered.
Contingency is thus necessity seen from its incomplete side. Whoever grasps the context widely enough finds the conditions; whoever grasps it narrowly finds contingency. And this is why contingency passes over into necessity: not because the contingent disappears, but because it proves to be dependent on the scope of what is considered.
In practice: Whoever says “that was chance” is thereby making a statement about the reach of their own view, not about the matter itself. This is not determinism — it remains open whether every context can be grasped completely. But it forbids taking chance as an explanation.
Compossibility (mutual fitting-together): Not only “Is A possible?” but “Can A and B be possible together?” Think of two wishes that exclude one another: “I want to save as much as possible” and “I want to live in luxury.” Formally each is possible on its own, but together they are incompatible. The dialectical question: can the contradiction be resolved in a higher form (for instance: investing wisely for the long term)? Ethical consequence: the test of justice is at its core a test of compossibility — can what I want for myself coexist with what everyone else wants for themselves? Going deeper: a structural example: capital accumulation and ecological sustainability as a structurally produced incompatibility — not solvable individually, requiring structural transformation. Worked out in [[kapitalismus-transformieren]] (optional).
Substance and Causality
Reality condenses into substance — but not as a dead substrate, rather as a power that posits and withdraws its changing properties (accidents). Spinoza as the “dark background”: his one substance (Deus sive Natura) elegantly resolves the Cartesian problem — instead of two separate substances (extension, thought) that a pineal gland must join together, Spinoza grasps both as attributes of one and the same substance. What Descartes keeps apart, and what Leibniz brings together only through a “pre-established agreement” (pre-established harmony), is with Spinoza one from the outset. Within each attribute there are infinitely many modes — the individual things (this table, that thought). Hegel’s critique: Spinoza explains that there are modes (they follow from the nature of God as the 180° follow from the triangle), but not how the one substance differentiates itself into many modes — where the inner dynamism comes from that lets the many finite things become out of the one infinite. Substance has modes, but it does not produce them out of an inner activity. It rests in eternal self-identity. Hegel’s extension: substance must become subject — it must differentiate itself actively, not merely “have” modes. Differentiation is not a defect but the way in which substance realizes itself.
“The Matter Itself” — The Truth Principle of the Logic of Essence
Between appearance (Chapter 6) and actuality (Chapter 7) stands a transition that Hegel calls “the matter itself.” Work through this: In an argument, someone says: “Let’s get to the matter at hand.” What does he mean? Not a particular perspective, but that about which all perspectives are speaking — the shared point of reference. “The matter itself” is what shows itself, through all subjective representations, as what is actually at stake. It is neither the inner (the hidden essence) nor the outer (the surface), but the unity of both: what shows itself in the matter, and the matter that shows itself. This is the truth principle of the logic of essence: truth is not something hidden that we must seek, but what arises of itself from an honest engagement with the phenomena.
Causality — Three Stages
Trace the transition: Why isn’t substance enough? Because it explains what stands behind appearances, but not why something happens. The transition to causality is the step from “What is there?” to “Why does it happen?”
1. Formal causality: cause -> effect as an abstract relation. “The storm knocked down the tree.” That sounds simple, but it’s problematic: what is “the storm”? A complex of pressure differences, temperatures, soil moisture — “the one cause,” looked at closely, dissolves into countless conditions. Hume’s skeptical objection: we never see causation, only temporal succession. Hegel’s answer: Hume is right that formal causality is insufficient — but wrong to think it’s merely habit. Causality must develop.
2. Determinate (finite) causality: the cause loses itself in the effect — it passes into it and is then “used up.” The match has burned out once it has lit the candle. Every effect becomes the cause of the next (domino effect): A causes B, B causes C, ad infinitum. This is the bad infinity of causality — the endless regress. In practice this means: if someone asks “What was the cause?”, the honest answer is always: “There is no the cause, only a web of conditions.” Anyone who insists on the one cause is simplifying ideologically.
3. Infinite (free) causality: the cause remains preserved in the effect — it does not lose itself. Illustrative images: the sun shines and is not used up (on human timescales). The teacher teaches and thereby does not become dumber but wiser. These images illustrate the logical structure but do not prove it — the proof lies in thinking through the stages of causality themselves. The decisive turn: the effect reacts back upon the cause. The student changes the teacher. The effect becomes the cause of the cause -> reciprocal action [interaction].
Reciprocity — The Highest Form of the Logic of Essence
Try this: Take a seemingly one-sided causal relationship — “education shapes the child.” True enough. But the child also shapes those who raise it. And which child it is determines what kind of upbringing takes place, which in turn determines what kind of child emerges. There is no fixed first and second term — both constitute each other reciprocally in the process. Once you have seen this, you will no longer find purely one-sided causality anywhere.
In reciprocity, A and B mutually constitute each other: each moment is both determining and determined, and both exist only within this mutual determination. Theory shapes observation, observation corrects theory. Language shapes thought, thought changes language. Supply and demand determine each other — there is no “market price” that exists independently of both.
The highest stage: reciprocity recognizes itself as reciprocity. It is no longer merely a factual mutual determination but a mutual determination that knows itself. What does this mean concretely? A couple who understand that they shape each other can consciously shape this shaping. A science that understands that theory and empirical observation determine each other can organize this process methodically.
The Truth of Necessity Is Freedom
If A is determined by B and B by A, then the system A–B determines itself. External determination (necessity/causality) flips over into self-determination — which, performatively, means: whoever recognizes that they are determined by circumstances can begin to shape those circumstances consciously. This is the logical birth of freedom. Three stages: blind necessity (laws act, but are not understood — the stone falls), recognized necessity (the reason why it must be so is grasped — the physicist understands gravitation), free necessity (the thinking being recognizes that it itself carries out the structures — the philosopher recognizes that he applies the categories, rather than merely undergoing them). Freedom is not arbitrariness, but recognized and appropriated necessity.
