Jeremy Butterfield

In several papers, Butterfield has collaborated with the theoretical physicist Chris Isham. These address the role of topos theory in understanding quantum theory (in particular the Kochen–Specker theorem), and the status of time in the various quantum gravity research programmes.

In recent years, Butterfield has argued for a reconciliation of the idea of emergence – the idea that novel structures, not described by "fundamental" theories, appear at a certain level of complexity – with the possibility of inter-theoretic reduction. He has illustrated the reconciliation in various areas such as phase transitions, renormalization, and gauge theories. He has also worked, often in collaboration with research students, on other topics, including: (i) identity and individuation of systems in quantum physics; (ii) dualities especially gauge/gravity duality; (iii) under-determination, and scientific realism, in modern cosmology.

Butterfield is a fellow of the British Academy and a senior research fellow of Trinity College, Cambridge. He is a past president of the British Society for the Philosophy of Science, and of the Mind Association. He previously served on the governing board of the Philosophy of Science Association and on the executive committee of the British Philosophical Association. He co-founded the journal Studies in History and Philosophy of Modern Physics, and edited it until 2001. He serves on the editorial boards of several journals and book series.

Butterfield obtained his Ph.D. from the University of Cambridge in 1984; he was supervised by Hugh Mellor and David Malament. He was a lecturer in the philosophy faculty at Cambridge University and was later promoted to reader in 1997. In 1998, he became a senior research fellow at All Souls College at the University of Oxford; he returned to the University of Cambridge in his present position in 2006. He has held visiting positions at Princeton University, the University of Pittsburgh and the University of Sydney.

Jeremy Nicholas Butterfield FBA (born 1954) is a philosopher at the University of Cambridge, noted particularly for his work on philosophical aspects of quantum theory, relativity theory and classical mechanics.

In the philosophy of spacetime physics, Butterfield has argued for a resolution of Einstein's 1913 hole argument that preserves spacetime substantivalism by utilizing David Lewis's theory of modal counterparts. More recently, he has appealed to tensor calculus, and its use in much of contemporary physics, to argue against the popular view (propounded by David Lewis) that the world may be described in terms of 'local matters of fact'; i.e. in terms of chiefly intrinsic properties instantiated at spatial or spatio-temporal points.
