 Austin was much impressed by Prichard, whom he thought the most rigorous and minute thinker in Oxford (Berlin, 1973, 2). J. O. Urmson told me that Austin had attended Prichard’s lectures as an undergraduate in the early 1930s, sat right at the front and asked very many questions. Eventually Prichard wrote to Austin’s tutor in Balliol (I’m not sure who that was), asking him to persuade Austin either not to ask so many questions, or not to attend at all. But Austin did neither of these things. Urmson himself wrote ‘As a member of the very last generation of undergraduates to attend Prichard’s lectures and informal instruction, I learnt to admire his patience as a teacher, his philosophical acuity and, above all, his quite exceptional intellectual honesty and independence.’ (This is in his introduction to his Prichard collection, reprinted in MacAdam, p. x.)
