Now updated to incorporate more selections from modern philosophers and a more thorough, organized treatment of contemporary epistemology, this collection of readings deftly blends the foremost classical sources with important contemporary philosophical thinkers to present a far-reaching examination of the theory of knowledge. Formative voices of epistemology from ancient Greek philosophy, medieval philosophy, classical modern philosophy, pragmatism, and contemporary analytic philosophy are amply represented. Organized chronologically and thematically, Human Knowledge presents an impressive collection of essays from Plato, Aristotle, Sextus Empiricus, Augustine, Aquinas, Descartes, Locke, Leibniz, Berkeley, Hume, Kant, James, Russell, Wittgenstein, Carnap, Quine, Gettier, Kripke, and many others. With section overviews by the editors, including a substantial general introduction, and helpful, up-to-date bibliographies, this definitive work offers the ideal introduction to our ancient struggle with the shape of our own intellectual experience.
