Abstract

Lawrence Bonjour supported coherentism in the early period, but turns to foundationalism in the later period. In this paper I shall focus on two sides in relation to his epistemology. To understand his early and later positions, first, I shall explain his coherentism and foundationalism. Second, I shall consider what objections have been raised to each position. Thus we can evaluate why Bonjour abandoned his coherentism and why his foundationalism succeeds as a plausible theory for empirical justification.
