Abstract

This article uses the current post-truth crisis to level a charge against deflationism. It argues that a post-truth society rejects the normativity of truth, thereby deflating truth, by treating disagreements about, say, scientific facts, as mere disagreements of taste. To have substantive disagreements, the notion of truth at stake must be substantive as well. To ward off the perils of post-truth politics, truth must be taken to be more than what deflationists can account for. If we want our disagreements to amount to more than mere differences of opinion, we should have an inflated notion of truth. The article concludes with putting this claim within the context of conceptual engineering.
