What Physics Learns From Philosophy

...what about the oft-heard claim that philosophy, unlike science, makes no progress? As Bertrand Russell (himself no slouch at physics and mathematics) observed, philosophy aims at knowledge, and as soon as it obtains definite knowledge in a specific area, that area ceases to be called “philosophy.” And scientific progress gives philosophers more and more to do. Allow me to quote Nietzsche (although I know that will be considered by some to be in bad taste): “As the circle of science grows larger, it touches paradox at more places.” Physicists expand the circle, and philosophers help clear up the paradoxes. May both camps flourish.
