Sobre Verdade e Mentira no Sentido Orientado a Objeto

Abstract

This article begins with a treatment of Friedrich Nietzsche’s early essay “On Truth and Lie in the Extra-Moral Sense.” The essay is often read, in the deconstructive tradition, as a showcase example of the impossibility of making a literal philosophical claim: is Nietzsche’s claim that all truth is merely metaphorical itself a true statement, or merely a metaphorical one? The present article claims that this supposed paradox relies on the groundless assumption that all philosophy must ultimately be grounded in some unshakeable literal truth. From here, we turn to Edmund Gettier’s famous critique of the widespread notion of knowledge as “justified true belief.” Expanding on Gettier’s point, it is argued that there can only be “justified untrue belief” or “unjustified true belief,” never a belief that is both justified and true at once.
