Is truth objective or relative? What exists independently of our minds? The essays in this book debate these two questions, which are among the oldest of philosophical issues and have vexed almost every major philosopher, from Plato, to Kant, to Wittgenstein. Fifteen eminent contributors bring fresh perspectives, renewed energy, and original answers to debates of great interest both within philosophy and in the culture at large.

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, skepticism, testimony, assertion, and perception, and debate Williamson's central claim that knowledge is a mental state.
