Philip Stuart Kitcher (born 1947) is a British philosophy professor who specializes in the philosophy of science, the philosophy of biology, the philosophy of mathematics, the philosophy of literature, and, more recently, pragmatism.

Born in London, Kitcher spent his early life in Eastbourne, East Sussex, on the South Coast of the United Kingdom. He earned his B.A. in Mathematics/History and Philosophy of Science from Christ's College, Cambridge in 1969, and his Ph.D. in History and Philosophy of Science from Princeton University in 1974, where he worked closely with Carl Hempel and Thomas Kuhn.

Kitcher is best known outside academia for his work examining creationism and sociobiology. His works attempt to connect the questions raised in philosophy of biology and philosophy of mathematics with the central philosophical issues of epistemology, metaphysics, and ethics. He has also published papers on John Stuart Mill, Kant and other figures in the history of philosophy. Lately he has become interested in John Dewey, and he recently published a book outlining a naturalistic approach to ethics, The Ethical Project (Harvard University Press, 2011). (FUENTE: WIKIPEDIA)
