 Meléndez is a professor at the Universidad Nacional de Colombia, where he also obtained his Ph.D. in philosophy. In his 1998 book, he explores the notion of truth from the vantage point of Wittgenstein’s later philosophy, although he also takes into account the conception of truth defended in the Tractatus. Meléndez’s main aim is to call into question the attempts to construct a general theory of truth that would make it rest on an ultimate and unshakable foundation. In a later publication, he discusses Wittgenstein’s examination of the notions of justification, persuasion, and world-picture (Weltbild) in On Certainty, focusing on whether world-pictures are taken to be incommensurable and hence on whether Wittgenstein endorses a form of epistemic relativism (Meléndez 2014).
