Laurence BonJour (born August 31, 1943) is an American philosopher and Emeritus of Philosophy at the University of Washington.
[2] He received his bachelor's degrees in Philosophy and Political Science from Macalester College and his doctorate in 1969 from Princeton University with a dissertation directed by Richard Rorty.
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).
[4] He formulated the examples of a clairvoyant and her reliable forecasts about the presence of the U.S. president in New 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 the regress problem in epistemology: he wrote that this central concept is itself by no means unproblematic.
