This course is a world-leading centre for research in three broad areas of philosophy: decision, rational choice and game theory; philosophy of science; and moral and political philosophy. It is committed to research that makes a significant difference not only to philosophy and the philosophies of the various sciences, but also to the practice of the sciences themselves – from economics and political science to physics, biology and medicine – as well as to the wider world. The Department’s teaching is research-led: courses cover cutting-edge material and are taught by experts in the field. The Department is a small, highly-integrated and friendly place to pursue a research degree. Students attend research seminars with faculty, and there are several specialist research groups MPhil students are encouraged to join. We have very close links with the Centre for the Philosophy of Natural and Social Science (CPNSS). Students in both the MPhil and PhD levels receive the opportunity to teach the undergraduate discussion classes that are run in parallel with lectures. An essential part of becoming a good philosopher is learning how to teach, share and discuss ideas with those interested in philosophy at all levels, and the discussion classes you lead at LSE will provide ample opportunity.
