In the autumn of 1952, Feyerabend moved to London for a year of research. He attended lectures by PopperPopper, Karl Raimund and participated in his seminars. However, Feyerabend refused to treat falsificationism as a sacrament and preferred instead to review Wittgenstein’s “Philosophical InvestigationsWittgenstein, Ludwig” and to continue his singing lessons. When Feyerabend’s scholarship for his stay in England expired in the summer of 1953, he returned to Vienna. From 1953 to 1954, he took up an assistant position with Arthur PapPap, Arthur, who had come to the University of Vienna for a year. When Popper announced in 1954 that he had secured the funds to offer Feyerabend an assistant position in London, Feyerabend declined. He did so, citing his current vocal training and the opportunity to take on a solo part at the Vienna Konzerthaus. Nevertheless, his interest in philosophy remained. Feyerabend applied for various positions and received a three-year appointment as a lecturer in philosophy of science at the University of Bristol. During this time, Feyerabend also came to know and appreciate the philosophers and physicist Philipp FrankFrank, Philipp and David BohmBohm, David. Bohm’s argument, never to exclude alternative theories, left its mark on the pluralistic views of the later Paul Feyerabend. And then he met his second wife, Mary O’Neill. However, the love and the marriage did not last long. In 1958, Feyerabend accepted an invitation to spend a year at the University of California in Berkeley.
