The question whether truth is correspondence, coherence, pragmatic utility, or something else is a perennial philosophical question for which there has so far been no decision procedure. In this talk I propose a decision procedure for this question. The basis for this decision procedure is the consideration of what we lose and what we don’t lose when we lose truth in a “post-truth” crisis. “Post-truth crisis” can be understood, in this context, either as the actual crisis taking place today or as a thought experiment.
