Abstract

There is an intuitive and seemingly significant difference between lying and falsely implicating. This difference has received scrutiny both historically and recently, mostly in the context of the following two questions. First, how should lying be defined so as to distinguish it from falsely implicating? Second, is the difference between lying and falsely implicating really significant, and if so, how and why is it significant? Answers to the first question typically invoke assertion, claiming (roughly) that to lie is to assert something you take to be false, as opposed to merely implicating something you take to be false. The task is then to spell out the account of assertion that is needed for a satisfactory definition of lying. Answers to the second question divide over whether the difference between lying and falsely implicating has moral significance. This chapter will review and critically evaluate the current state of the literature on these two questions. One conclusion will be that it is not clear that lying can be defined by breaking it down into the components of asserting something, on the one hand, and taking that something to be false (or not taking it to be true), on the other. Another conclusion will be that a puzzle has emerged about the significance of the difference between lying and falsely implicating. There is strong reason to think that the difference is not a moral one, yet alternative explanations of its felt significance are unsatisfying. Finally, an effort will be made to link the two questions by examining the role that norms for assertion might play both in defining lying and in explaining the significance of the difference between lying and falsely implicating.
