Philosophy is a disciplined way of framing and seeking answers to questions of important human concern. It seeks to illuminate fundamental aspects of the world (metaphysics), of our relation to and knowledge of it (epistemology, philosophy of mind), and of our own nature as rational, purposive, and social beings (ethics, political philosophy). The study of philosophy aims at an appreciation of the ways this enterprise has been, is, and might be approached. It also provides a vantage point for reflecting on the nature and achievement of other disciplines, such as science, the arts, and the humanities.
