Say what a thing is
A definition must identify what makes its object recognizable without reducing it to an accidental feature.
The philosophical problem
Thinking determination without arbitrarily separating the form of thought from the structure of reality
Thesis
When we say that something is a cause, a person, an institution, or a freedom, we are not merely applying a label to a datum that is already fully formed. We are determining an identity, a limit, a set of relations, and a field of consequences.
The issue is therefore more radical than classification: what makes it possible for reality to be determinable without becoming an arbitrary construction of the subject? The expression ontology of the concept names precisely this problem.
The concept has validity only if its form can articulate constraints that do not depend on the thinker’s caprice. Its claim is therefore both ontological and critical: it concerns reality, but it must demonstrate its own adequacy.
Criterion
A definition must identify what makes its object recognizable without reducing it to an accidental feature.
Every identity gains precision through justified exclusions. An indeterminate limit yields only more rigid words, not greater truth.
What appears autonomous may exist by virtue of conditions, practices, or relations that the definition must make visible.
Test
It is not enough to assert that thought and being coincide. One must show that the chosen determination better explains its object, preserves its relevant differences, and withstands cases that could disconfirm it.
A form is immanent when it is not imposed from outside but emerges from the relations without which the object would lose its intelligibility. It is a projection, by contrast, when it eliminates what does not fit the scheme and turns the theory’s limit into a defect of reality.
This distinction makes the system open to challenge: a real counterexample, an excluded dependency, or an incompatible consequence requires the formulation to be revised.
Example
Describing it as a building, a rule, or a group of people captures genuine but partial aspects. An institution exists through recognized roles, reiterated practices, distributed powers, and shared expectations.
Its reality is no less concrete because it includes relations. On the contrary, those very relations explain why it continues to operate even when the individual people who compose it change. Here the concept does not replace reality; it makes its structure visible.
