Compare foundationalism, coherentism, and reliabilism as theories of epistemic justification. How does each theory address the regress problem (the problem of infinite justification chains)? Discuss the Gettier problem and its implications for the traditional analysis of knowledge as justified true belief. Examine virtue epistemology as an alternative approach focused on intellectual character. Consider the relationship between internalism and externalism about justification. Evaluate which theory best accounts for our intuitive understanding of knowledge and justification.
