Augustine's exposition of the image of God in Book 15 of On The Trinity sheds light on multiple issues that arise in scholarly interpretations of Augustine's account of lying. This essay argues against interpretations that posit a uniform account of lying in Augustine—with the same constitutive features, and insisting both that it is never necessary to tell a lie and that lying is absolutely prohibited. Such interpretations regularly employ intertextual reading strategies that elide distinctions and developments in Augustine's ethics of (...) lying. Instead, I show how looking at texts written prior and subsequent to the texts usually consulted suggests a trajectory in Augustine's thought, beginning with an understanding of lies as morally culpable but potentially necessary, and culminating in a vision of lying as the fundamental evil and the origin of every sin.

This thesis addresses philosophical problems concerning improper assertions. The first part considers the issue of defining lying: here, against a standard view, I argue that a lie need not intend to deceive the hearer. I define lying as an insincere assertion, and then resort to speech act theory to develop a detailed account of what an assertion is, and what can make it insincere. Even a sincere assertion, however, can be improper (e.g., it can be false, or unwarranted): in the (...) second part of the thesis, I consider these kinds of impropriety. An influential hypothesis maintains that proper assertions must meet a precise epistemic standard, and several philosophers have tried to identify this standard. After reviewing some difficulties for this approach, I provide an innovative solution to some known puzzles concerning the permissibility of false assertions. In my view, assertions purport to aim at truth, but they are not subject to a norm that requires speakers to assert a proposition only if it is true. (shrink)
