Why the unity must divide against itself
Life is the unity of concept and objectivity — but an unconscious unity. It lives without knowing that it lives. The organism digests without knowing biochemistry. Cognition and volition are the splitting of this unity into two opposing movements — and both directions must be traversed before the unity can be consciously reestablished.
Theoretical Idea — Cognition
Cognition is the attempt to grasp reality in thought — to penetrate it and to comprehend it. Direction: World -> Concept. Two forms:
Analytical cognition: Decomposition of what is given into its component parts. The chemist analyzes water and finds H₂O. The grammarian breaks the sentence down into subject, predicate, object. Strength: It finds what is there. Limit: It can only find what it is already looking for — the categories of decomposition (elements, parts of speech) are presupposed, not derived from the matter itself. Analytical cognition explains what is already known but discovers nothing new.
Synthetic cognition: Construction proceeding from principles — definition, division, proof. Geometry defines the circle, divides it into diameter, radius, circumference, and proves the relation between them (C = 2πr). Strength: It generates necessary knowledge (the proof compels the conclusion). Limit: The initial definitions and axioms are assumed, not proven — synthetic cognition rests on unproven foundations. That is why mathematics can prove everything within its axioms, but not the axioms themselves.
Trace the transition: Analytical cognition cannot truly understand what is given (it presupposes its categories). Synthetic cognition cannot prove its own foundations. Together the two exhaust theoretical cognition — and both are incomplete. This forces the move to the practical idea: if cognition cannot fully grasp the world, one must try to change it — and in changing it, come to understand it better.
Practical Idea — Willing
Willing is the attempt to reshape reality according to purposes — to realize the good. Direction: concept -> world. The engineer plans the bridge, the reformer the state, the physician the cure. Strength: It actually changes the world. Limit: The will alone remains “subjective” — a mere ought, which experiences the world as resistant. And: how does the will know what is good? It needs cognition to test its purposes — practice points back to theory.
The Price of Consciousness
Life was immediate unity (the organism lives without asking questions). Cognition divides this unity — it separates subject and object, theory and practice. This is a loss (innocence, naiveté, certainty) and a gain (testability, correction, freedom). The price of consciousness is division; its reward is the possibility of conscious reunification in the absolute idea.
Deliberately no complete mediation in K21: The point is precisely this incompleteness. Cognition and will remain referred to one another, without either side absorbing the other. Theory without practice is empty, practice without theory is blind. The unity of both — a reality that comprehends itself, and a comprehension that shapes reality — is the absolute idea.
