Why assertion and practical reasoning must be governed by the same epistemic norm

Abstract

I argue that assertion and practical reasoning must be governed by the same epistemic norm. This is because the epistemic rule governing assertion derives from the epistemic rule governing practical reasoning, together with a plausible rule regarding assertion, according to which assertion must manifest belief. © 2012 The Author.
