Not Every Deliberately Willed Spoken Falsehood Is a Lie: Formulating a Polyvalent Thomistic Theory of Speech Acts

For the most part, the ongoing Thomistic debate over the nature of lying presupposes that speech has one primary end: to reveal the speaker’s mind or soul. Within this framework, a lie is disordered speech. In this paper, I formulate a polyvalent Thomistic theory of speech acts that affirms that human vocalizations have multiple ends in the order of nature, including functions that do not involve signification, a claim supported by evidence from studies of primate vocalization and by evidence from studies of contemporary speech act theory in the philosophy of language. With this theory in hand, I propose that not every deliberately willed spoken falsehood constitutes a lie, including false claims made to enemy spies and Nazi officers, because not every spoken falsehood involves disordered speech.
