BonJour is best known for his contributions to epistemology. Initially defending coherentism in his anti-foundationalist critique The Structure of Empirical Knowledge, BonJour has since moved to defend Cartesianfoundationalism in such works as Epistemology and In Defense of Pure Reason. The latter book is a sustained defense of a priori justification, strongly criticizing empiricists and pragmatists who dismiss it (such as W. V. O. Quine and Richard Rorty).
