What Is Science?

Ian Hacking, who has been interested in the nature and role of experiment in science, once said that science involves (sometimes? always?) "speculation, calculation, and experiment." Representing and Intervening: Introductory Topics in the Philosophy of Natural Science 215 (1983). Ian Hacking has been a student of the history of science, and he has been influenced by the relativizing tendencies of theorists such as Thomas Kuhn. But, he says, he, Hacking, is not a relativist. He might be called -- he has called himself -- a "pragmatic realist."
