"New essays on scepticism about the senses explore the problem of whether and how experience can provide knowledge or justification for belief about the objective world outside the experiencer's mind."@en
"One of the hardest problems in the history of western philosophy has been the problem of explaining whether and how experience can provide knowledge (or even justification) for believing that the objective world outside the experiencer's mind is thus and so. A prominent brand of scepticism has precisely denied that experience can provide such knowledge. How-these sceptics for instance ask-can I know that my experiences are not produced in me by a powerful demon (or, in a modern twist on that traditional Cartesian scenario, by a supercomputer)? This volume, originating from the research project on Basic Knowledge recently concluded at the Northern Institute of Philosophy, contains chapters on scepticism about the senses written by some of the most prominent contemporary epistemologists."
