Moorean constructions are famously odd: it is infelicitous to deny that you believe what you claim to be true. But what about claiming that p, only to immediately put into question your evidence in support of p? In this paper, we identify and analyse a class of quasi-Moorean constructions, which we label counterevidentials. Although odd, counterevidentials can be accommodated as felicitous attempts to mitigate one’s claim right after making it. We explore how counterevidentials differ from lexicalised mitigation operators, parentheticals, and (...) anaphoric mitigation devices, and consider some cognate non-assertoric constructions. We conclude by exploring the implications of our analysis for theorising about linguistic responsibility, assertion, and lying. (shrink)

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)
