Abstract

Emanuel Viebahn accounts for the distinction between lying and misleading in terms of what the speaker commits to, rather than in terms of what the speaker says, as on traditional accounts. Although this alternative type of account is well motivated, I argue that Viebahn does not adequately explain the commitment involved in lying. He explains the commitment in lying in terms of a responsibility to justify one's knowledge of a proposition one has communicated, which is in turn elaborated in terms of being able to consistently dismiss a challenge to justify that knowledge. But whether one can consistently dismiss such a challenge, as Viebahn defines this, depends on whether one is responsible for justifying one's knowledge. Without further specification of the nature of this justificatory responsibility, it is difficult to assess whether it is one that liars have but misleaders lack.
