Distinction is possible only against a background of the undistinguished. Thus, the question of the undifferentiable belongs to the very foundations of philosophy: by excluding the background, philosophy excludes the condition without which what is distinguished cannot be given.
The Original Dependence
The inquiry begins with the observable structure of experience and a logical necessity:
- There is an act of distinction.
- Distinction is possible only against the background of the undistinguished.
- The background is structurally necessary and is given together with the distinction.
- Therefore, it cannot be excluded from the philosophical foundation.
The duality of the distinguished and the undistinguished is discovered within the very structure of distinction. It does not require prior acceptance of a separate doctrine.
Knowledge of the Boundary
The existence of the undifferentiable already belongs to knowledge. This is knowledge of the boundary of distinction, not a complete description of an object.
The absence of an exhaustive description does not place the boundary itself outside knowledge. Form is understood as an operation that establishes a distinction. It does not exhaust being.
Rigor consists in consistently acknowledging the complete structure of experience. Restricting consideration to the formalizable may be a technique for a particular task, but it cannot replace that requirement.
Exclusion from the Foundation
The objection “the undifferentiable is not denied; it is merely not recognized as a foundation” does not resolve the ontological problem.
If something is encountered in reality and is structurally necessary for distinction, refusing to take it into account in the foundation changes the very picture of being. Declaring it “pre-philosophical” does not eliminate the dependence of what is distinguished upon its background.
Philosophy may work with already established forms when addressing a particular task. Yet working only with what has been distinguished does not constitute a complete ontology: the condition of its emergence remains outside the explanation.
Logical Consequence and the Catalog of Positions
Distinguishing between philosophical schools is no substitute for examining the original dependence. If the thesis that distinction requires a background has been accepted, acknowledging that dependence follows from the accepted premise.
Presenting formalism, mysticism, and duality merely as equally valid alternatives creates a false symmetry here: it substitutes a list of opinions for a logical question.
What matters for evaluating an argument is what is observed and what follows from the observation. Motives, fears, and affiliation with a philosophical school may explain people’s behavior, but they do not establish whether a thesis is true.
The Universality of Formalization
The thesis “only what can be formalized exists” is a strong ontological claim. It requires demonstrating that the non-formalizable background is an illusion.
But the background is already structurally given together with distinction. Its exclusion cannot be regarded as a neutral methodological decision: it affects the very ground from which form itself arises.
Recognizing the Background and Rigor
Recognizing the undifferentiable does not negate form. It makes it possible to examine form’s origin.
The objection that such recognition would lead to chaos and arbitrariness itself presupposes a distinction: “chaos” has already been named and contrasted with something else. The objection does not remove the need to explain the structure of distinction and its background.
Consistency requires maintaining both moments, the distinguished and the undistinguished. Recognizing this dependence is a consequence of the structure of experience, not a replacement of argument with philosophical preference.
