Truthmaking

Truthmaking is the relation between a truth-bearer — typically a proposition or statement — and the portion of reality that makes it true. The proposition 'snow is white' is made true by the actual whiteness of actual snow; the proposition 'electrons carry negative charge' is made true by the properties of electrons. Truthmaking is not merely correspondence in the sense of structural mirroring. It is a relation of ontological dependence: the truth of the proposition depends on the existence and character of its truthmaker. Without the truthmaker, the proposition would not be true, even if it might still be meaningful.

The doctrine raises a structural question that parallels debates about ontological dependence and grounding. If every truth requires a truthmaker, then the inventory of truthmakers constrains the inventory of acceptable truths. Negative truths — 'there are no unicorns' — are particularly problematic: what in reality makes a negative proposition true? Some philosophers posit negative facts or totality facts; others deny that negative truths require truthmakers at all, treating them as mere absences of positive truthmakers for their contradictories.

The systems-theoretic insight is that truthmaking, like grounding, is a network relation. The truth of a scientific theory is not made true by any single fact but by a distributed pattern of experimental results, instrumental calibrations, and community practices. The truthmaker is not a atom but an ecology.
