Professor Ian Hacking explores how our innate sense of symmetry has enabled us to probe the hidden secrets of nature and also get along with each other. He presents a new development in his philosophy; one that remains in the spirit of what has established his reputation as a "Philosopher of the Particular Case." Hacking brought a new understanding of how statistics changed the world and how we think about it, from sociology to physics. His "Representing and Intervening" (1983) returned philosophers of science to their roots - experimental science. It began what he calls a "back to Francis Bacon movement." (#20382)
