Philip Kitcher is the John Dewey Professor of Philosophy at the University of Columbia. He’s the first recipient of the American Philosophical Association’s Prometheus Prize for his work to expand the frontiers of science and philosophy. He’s written many books including ‘Philosophy of Science: A new introduction’, ‘Preludes to Pragmatism’ and ‘The Ethical Project’. His latest book is ‘Life after Faith: The Case for Secular Humanism’ and that will be the topic of the conversation today.
