Commentary on the Logic, Chapter 6
Organizing Principle of the Logic of Essence
The doctrine of essence makes the mediation structures themselves the theme — those structures that were tacitly at work in the doctrine of being, as all immediate determinations proved to be mediated. The new form of movement is no longer transition (A disappears, becomes B), but shining into one another — reciprocal constitution, in which both sides are preserved and mutually determine each other. A mirror instead of a line.
The guiding thread remains the question of truth, but on a new level: No longer “What is true?” (being), but “How is the true mediated?” — how do grounding, appearance, actuality function?
The entire doctrine of essence accomplishes the movement from implicit to explicit reflection: What was tacitly at work in the doctrine of being — mediation, grounding, reciprocal constitution — is here consciously comprehended. This movement is the fundamental structure of all thinking that enlightens itself about itself.
