Monograph developing an integrated, knowledge-based account of the normativity of constative speech, in conjunction with classical invariantism about knowledge attributions.

Monograph investigating the relation between knowledge sharing and assertion, and developing a functionalist account of what it is to assert well. 

The first volume to explore the topic of defeat in all its facets. Brings together work in epistemology, ethics, and practical reasoning.
