The second volume in the Blackwell Brown Lectures in Philosophy, this volume offers an original and provocative take on the nature and methodology of philosophy.

• Based on public lectures at Brown University, given by the pre-eminent philosopher, Timothy Williamson
• Rejects the ideology of the 'linguistic turn', the most distinctive trend of 20th century philosophy
• Explains the method of philosophy as a development from non-philosophical ways of thinking
• Suggests new ways of understanding what contemporary and past philosophers are doing
