he said. âItâs the next big problem, the basis of how we learn ⦠everything.â
They walked across the Downing Site, turned right into Downing Street.
Douglas stood on the pavement, talking emphatically.
âThat building weâve just been in, Physiology. Some of the most important research on the nervous system is going on right there. That would be learning about science, but of course as undergraduates we see nothing. But thatâs the place. Professor Adrian is there. Itâs electronics now. Thatâs how the brain works.â
âAnd thatâs what you want to do?â
âIn Part II, I want to do Experimental Psychology. Itâs a small group, but with Bartlett, the head of the department. Heâs got the right idea.â
Whereas for George the syllabus on the way to medicine was mapped out for him, Douglas had somehow managed to create his own mixture: maths, physics, physiology.
With a father whoâd been to Cambridge and was a professor at Manchester, Douglas knew where to go, who to talk to, what to do. Not the kind of thing on which Georgeâs mother, a primary-school teacher and the widow of a gentlemanâs outfitter, could offer guidance.

One drizzly afternoon in his last term of his last year at Cambridge, George lost patience with his revisions for finals. He bought some crumpets and went to visit Werner.
Werner was in. His wood-panelled room overlooked Great Court. On the walls, he had put up reproductions of Holbein, Dürer, and Cranach. He lit his gas fire, picked up the toasting fork, and started to toast the crumpets.
âI want to write a thesis,â he said. âCan you get the butter out, and plates?â
George did as he was asked.
âItâs the big unsolved problem.â
âWhat is?â said George.
âHow minds meet,â said Werner. âWhen minds are so different from each other, how can they connect?â
âWittgenstein, will he help?â
âHe is the most complete intellect in philosophy. Whether he will help ⦠I donât have a route yet, or a method.â
âI should introduce you to Douglas Hinton. He wants to find out about memory.â
âIs he doing philosophy?â
âExperimental psychology.â
âThat would be of no help to me. In psychology, problem and method pass each other by.â
âHow do you mean?â
âHereâs the problem,â said Werner. âWhen silk first came from China to Europe, the Romans, who knew about cotton, thought it must come from a bush, with a fruit in which the silk fibres grew.â
âNow we know it comes from silkworms.â
âYouâre not following. We see everything through what we know, through that by which we make propositions. If we had telepathy, even then I could not read your thoughts because minds are too different.â
âBut we can talk to each other.â
âPerhaps we only think we do.â
âIs that what your thesis will be on?â
âI want to solve the problem of how minds can join.â
âAnd thatâs the most important problem?â
Suddenly Werner looked very deliberate. âIf minds cannot join,â he said, âhow do we know we are not mad?â
Werner could be uncomfortable to be with. He sometimes made George feel inadequate. He had grand ideas, which he took up with total commitment.
George thought: What do I have? Attracted to knowledge but donât know much. Knowledge of Hegel nil. The Hanseatic League â what was that? A medical student without that essential fascination for the workings of the body. Werner talks about connection between minds. Am I even connected to my own mind?
Until George was thirteen, things went for him much as one would expect. It was as if life were a jigsaw. It wasnât that he knew which pieces were which, but they were all there. He needed merely to fit each into its place as time
