Bold and pioneering, this book makes a detailed historical and systematic case that Descartes's theory of knowledge is an elegant and powerful combination of a priori, naturalistic, and dialectical elements meriting serious consideration by both contemporary analytic philosophers and postmodern thinkers. In the course of making this case Thomas Vinci develops a broad reinterpretation of Cartesian thought that unlocks novel solutions to many of the most vexed questions in Cartesian scholarship.
