During the period roughly of the 1950s Oxford was generally regarded as the most important center of philosophy in the world, the one where the most interesting philosophical activity was going on. It was indeed so distinctive that the very name ‘Oxford Philosophy’ meant not just the philosophy that happened to be practiced in Oxford but a special kind of philosophy that gave a central importance to the study of language as the major topic of philosophical investigation. It is not an exaggeration to describe this period as a golden age of Oxford Philosophy. Quite by coincidence, my initial stay in Oxford from 1952–1959 happened to be during the high watermark of Oxford Philosophy.
