Timothy Williamson's 2000 book Knowledge and Its Limits is perhaps the most important work of philosophy of the decade. Eighteen leading philosophers have now joined forces to give a critical assessment of ideas and arguments in this work, and the impact it has had on contemporary philosophy. They discuss epistemological issues concerning evidence, defeasibility, scepticism, testimony, assertion, and perception, and debate Williamson's central claim that knowledge is a mental state.

Eighteen leading philosophers offer critical assessments of Timothy Williamson's ground-breaking work on knowledge and its impact on philosophy today. They discuss epistemological issues concerning evidence, defeasibility, scepticism, testimony, assertion, and perception, and debate Williamson's central claim that knowledge is a mental state.

The book turns out to be a very valuable tool with respect to these aims. ... intreguing and valuable.
