Within philosophy, Kitcher is best known for his work in philosophy of biology, science, and mathematics, and 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. His 2012 book documented his developing interest in John Dewey and a pragmatic approach to philosophical issues. He sees pragmatism as providing a unifying and reconstructive approach to traditional philosophy issues. He had, a year earlier, published a book outlining a naturalistic approach to ethics, The Ethical Project. He has also done work on the philosophy of climate change.
Criteria for what constitutes 'good science'
Kitcher's three criteria for good science are: He increasingly recognised the role of values in practical decisions about scientific research
Kuhn and creationism
Kitcher is the author of Abusing Science: The Case Against Creationism. He has commented on the way creationists have misinterpreted Kuhn:
Thomas Kuhn's book The Structure of Scientific Revolutions has probably been more widely read—and more widely misinterpreted—than any other book in the recent philosophy of science. The broad circulation of his views has generated a popular caricature of Kuhn's position. According to this popular caricature, scientists working in a field belong to a club. All club members are required to agree on main points of doctrine. Indeed, the price of admission is several years of graduate education, during which the chief dogmas are inculcated. The views of outsiders are ignored. Now I want to emphasize that this is a hopeless caricature, both of the practice of scientists and of Kuhn's analysis of the practice. Nevertheless, the caricature has become commonly accepted as a faithful representation, thereby lending support to the Creationists' claims that their views are arrogantly disregarded.
