So there are long conversations in cafes about Jean-Paul Sartre, and Simone de Beauvoir, and Albert Camus and Raymond Queneau, and all the boys that we were just beginning to get excited about in London when the first French literature filtered across after the Liberation. My God, Leo, there is some very interesting stuff being written in France at present on the philosophical and literary front. I begin to get some glimmering too about 'existentialism' the latest philosophy of France - Sartre, out of Husserl, Heidegger and Kierkegaard. Last week I had a very great experience. Jean-Paul Sartre came to Brussels to give a lecture on existentialism, and I met him after the lecture, and on the following day during an interminable cafe seance. He is small, squints appallingly, is very simple and charming in manner and extremely attractive. What versatility! Philosophy, novels, plays, cinema, journalism! No wonder the stuffy professional philosophers are suspicious. I don't make much yet of his phenomenology, but his theories on morals, which derive from Kierkegaard, seem to me first rate and just what English philosophy needs to have injected into its veins, to expel the loathsome humours of Ross and Prichard.
