(Professor Duncan Pritchard) We know a lot of things – or, at least, we think we do. Epistemology is the branch of philosophy that studies knowledge; what it is, and the ways we can come to have it. In this module, we’ll take a tour through some of the issues that arise in this branch of philosophy. In particular, we’ll think about what radical scepticism means for our claims to knowledge. How can we know something is the case if we’re unable to rule out possibilities that are clearly incompatible with it?
