Abstract

When you start to get self-conscious about what you know, even the simplest fact, something you usually think you could verify at a glance, can start to seem like something you don’t really know. ‘Scepticism’ describes the historical roots of scepticism beginning with the two distinct sceptical traditions: Academic and Pyrrhonian. A central worry of both schools of ancient scepticism concerns the ‘criterion of truth’ or the rule we should use to figure out what to accept, assuming that knowledge requires not just accepting things randomly. Modern approaches to scepticism from philosopher G. E. Moore and Bertrand Russell's ‘Inference to the Best Explanation’ to Hilary Putnam's Semantic Externalism and the brain-in-a-vat hypothesis are discussed.
