Knowledge and reasoning

Abstract This paper develops a novel, functionalist, unified account of the epistemic normativity reasoning. On this view, norms drop out functions. I argue that practical reasoning serves prudential function generating prudentially permissible action, and knowledge what one ought to do. picture, if right, goes long way towards normatively divorcing action At same time, it unifies epistemically: theoretical will turn be governed by norm—knowledge—in virtue serving function: conclusion.
