What is True?
“What is truth?”
This question does not belong exclusively to any single domain. Its primary home is epistemology, but it necessarily reaches into ontology and metaphysics.
In epistemology, “truth” concerns the status of knowledge-claims: what it means for a belief, proposition, perception, or judgment to be true, how truth is recognized, and how error is possible. Correspondence, coherence, pragmatic, and revelatory accounts of truth all live here.
In ontology, truth appears implicitly as the question of whether truth is a property of propositions, a disclosure of being, or identical with being itself. Classical formulations such as “being and truth are convertible” place truth at the ontological level.
In metaphysics, truth appears when one asks whether reality itself is ordered, intelligible, illusory, simulated, symbolic, or mental in nature. If reality is Maya, dream, simulation, or projection, truth cannot be reduced to simple correspondence.
“What is truth?” is epistemological in focus, ontological in depth, and metaphysical in implication.
