BonJour specializes inepistemology,Kant, andBritish empiricism, but is best known for his contributions to epistemology. Initially defendingcoherentism in his anti-foundationalist critiqueThe Structure of Empirical Knowledge (1985), BonJour subsequently moved to defendCartesianfoundationalism in later work such as 1998'sIn Defense of Pure Reason. The latter book is a sustained defense ofa priori justification, strongly criticizing empiricists and pragmatists who dismiss it (such asW. V. O. Quine andRichard Rorty).
In 1980, in his essayExternalist Theories of Empirical Knowledge, BonJour criticized thereliabilism ofArmstrong andGoldman, proposinginternalist approach to epistemic truth and knowledge justification.[4] He formulated the examples of aclairvoyant and her reliable forecasts about the presence of the U.S. president inNew York City.[4] To set the problematic of this essay, BonJour said that foundationalism, the most common form of internalism, requires the concept of a basic belief to solve theregress problem in epistemology: he wrote that this central concept is itself by no means unproblematic.[4]
