Introduction to the Philosophy of Physics

Marc Lange is Professor of Philosophy at the University of Washington. He is author of Natural Laws in Scientific Practice (2000).

"Marc Lange uses the philosophical tools of traditional metaphysics to analyze examples drawn from electromagnetic theory and quantum mechanics and in turn uses these examples to refine some of the basic concepts of traditional metaphysics. The result is an excellent introduction to the best sort of metaphysics, the sort that is informed by our best physical theories." Jeffrey Barrett, University of California, Irvine "This is philosophy of physics that meets even Feynman's challenge of making a difference for physics while it attains Hempel's standards of clarity. I can hardly imagine teaching the philosophy of physics, at any level, from introductory to graduate seminar, without using this book!" Alex Rosenberg, Duke University "Eschewing the technical jargon of philosophy of science, though he is a fluent contributor to journals and refers to current issues in appropriate notes, Lange employs a breezy, common language style, complete with discussion questions suitable for an undergraduate introductory class. [...] Highly recommended to philosphically inexperienced physicists as well as current students in philosophy of science. Lower-division undergraduates through faculty." P.D. Skiff, Bard College, Choice, January 2003 "An accomplished philosopher of science, Lange introduces the epistemological consequences of a central idea in physics - locality ... Eschewing the technical jargon of philosophy of science, though he is a fluent contributor to journals and feres to current issues in appropriate notes, Lange employs a breezy, commom language style, complete with discussion questions suitable for an undergraduate introductory class ... his introduction to the issues via concrete example is very effective and unique. Highly recommended to philosophically inexperienced physicists as well as current students in philosophy of science." Choice
