This is part one of a series about epistemology, the branch of philosophy concerned with knowledge and justification. When does something count as knowledge? How can we be justified in accepting mathematical truths, moral truths, and truths about the external world? Can I trust my perceptual faculties, my memory, my ability to reason? Can I know anything at all?  Today, we're discussing internalism vs. externalism about knowledge and justification. We also touch on the person-based nature of justification, giving others the benefit of the doubt, and empathy on the epistemic landscape. Understanding Knowledge - Michael Huemer  Linktree
