'radical and challenging . . . without question and important exercise of the "let me show you a new way of looking at things" kind; something we sorely need in epistemology'
Frank Jackson, Australasian Journal of Philosophy
'the best book in epistemology to come out since 1975'
Keith DeRose, British Journal for the Philosophy of Science
Williamson provides a battery of considerations designed to convince us that the concept of knowledge is the most central and vital member of the family of epistemological concepts ... If Williamson is right, we shall be forced to admit that much recent epistemology is ill-conceived... He also makes important contributions to our understanding of the nature of mind and the relationship of mind to world. Knowledge and its Limits is striking throughout for its clarity, originality of thought, technical sophistication and philosophical breadth ... Careful study of this work will be richly rewarded.
