William Demopoulos (1943-2017), editor of Frege's Philosophy of Mathematics and author of Logicism and Its Philosophical Legacy, spent nearly four decades as Professor of Philosophy at the University of Western Ontario. Michael Friedman is Patrick Suppes Professor of Philosophy of Science at Stanford University.
On Theories, a painstaking analysis of the seemingly straightforward concept of theory, takes us on an exciting journey through twentieth-century science and philosophy of science. It critiques naive dogmas such as the theory/observation dichotomy, replacing them with a nuanced account centered on the notion of 'theory-mediated measurement.' On the basis of this account, Demopoulos offers a novel interpretation of major breakthroughs in classical as well as quantum mechanics. Meticulous in its historical analysis and compelling in its philosophical argument, On Theories is a must for anyone interested in science and its method. -- Yemima Ben-Menahem, The Hebrew University of Jerusalem Demopoulos wrote 'for the eye of God and the good of my soul,' as he used to say. On Theories is a stunning achievement, a profound argument for a novel thesis about the nature of truth in scientific theories, ranging from case studies about our understanding of molecular reality to Bohr's dispute with Einstein about quantum reality. -- Jeffrey Bub, University of Maryland
