  In the summer break following the John Locke lectures, Prior organised a Logic Colloquium in Oxford. Logic was deeply out of fashion in 1950s Britain, and its practitioners were isolated and somewhat demoralized. As Prior wrote shortly after the Colloquium, ‘There are logicians in England and Ireland; but it must be admitted that they are somewhat scattered, and so far as I could gather they had never had any general get-together’ (1956b: 186). Prior’s Colloquium brought together Lemmon, Thomas, Geach, M. Kneale, W.C. Kneale, M.W. Dick, Lewy, Smiley, Bennett, Lejewski, Faris, Nidditch, Carew Meredith, David Meredith, and others. It was all a huge success, and the Colloquium became a regular fixture. Through his John Locke lectures, the Colloquium, and his numerous visits around the country, Prior helped to revitalise British logic. The group he left behind saw similarities between themselves and the close-knit group of researchers that existed in Warsaw before 1939.
