Philosophy translates to "love of wisdom"; It emerged as a discrete academic field thanks to ancient Greek thinkers like Aristotle and Pythagoras. Philosophy has been divided into five different sub-categories: logic, metaphysics, epistemology, ethics, and aesthetics. Meanwhile philosophy also often impacts—and is influenced by—other disciplines. The work of modern thinkers like Umberto Eco often pulls from philosophy and other related disciplines like semiotics or the sciences. Our collection of books on philosophy includes both works on philosophy itself and on philosophers themselves.
