This paper begins by exploring a subspecies of assertion. Under some circumstances an utterance intuitively counts as an assertion, even though it is Cynical: that is, it is insincere, and made without the reasonable expectation of even appearing sincere to its audience. The paper explores the contextual and cognitive workings of Cynical assertion – directly, in part, but also by comparison with superficially similar but non-assertoric utterances, namely, those made under duress. Finally, the paper examines the broader relevance of Cynical (...) assertion, by considering two philosophical applications of the notion: first, in support of Michael Dummett’s conventionalist account of assertion; and second, in illuminating an aspect of Moore’s paradox.
