Juan Comesaña is a contemporary analytic philosopher specializing in epistemology, with particular focus on the nature of justification, evidence, and the epistemic role of experience. He has developed influential positions on evidential internalism and the relationship between perceptual experience and epistemic warrant. His work engages centrally with debates over dogmatism, reliabilism, and the conditions under which beliefs count as justified.
