Epistemological scepticism
Ancient and modern debates
It examines arguments that challenge the possibility or scope of knowledge.
Historical context
Ancient schools practised forms of suspension of judgment. Modern accounts also raise problems about the external world and perceptual reliability.
Overview
A deception scenario asks what evidence could distinguish a veridical experience from an indistinguishable mistaken one. Depending on the argument, this may affect ordinary knowledge or a more demanding account of certainty.
Main claims
Sceptical arguments examine the limits of justification and claims to knowledge.
Debates and nuances
Arguments can target the external world, other minds, or specific domains.
