The author met Russell first as one of a small party, I think with Clough-Ellis or whatever the architect of Portmeirion was called; and he recalls his feeling of nervousness over possible embarrassments that might take place, or yawning silences, whatever. In fact he says Russell liked gossip and small talk. He records his later surprise that Russell and his wife felt nervous about asking them, in turn, to call. He couldn't believe Russell was so isolated.
Crawshay-Williams says at the time he knew nothing of philosophy; extraordinarily, Russell allowed him to read the MS of Human Knowledge while it was being written. C-W also reviewed volume 1 of Russell's Autobiography! And he puts in philosophical footnotes, clearly feeling that philosophy has rubbed off onto him. (C-W's book 'The Comforts of Unreason' was published in 1947). Some of this book was jotted down after chats (there's a similar book about Whitehead) but tape recorders, when they became available, were cumbersome.
Great many famous (not in the popular sense) people in passing: Brockway, Cantor, Deutscher, John Dewey, Eddington, Fermi, Anatole France, J B S Haldane, Alger Hiss, Holroyd, Julian Huxley, William James, Storm Jameson, Roy Jenkins, Arthur Koestler, G E Moore, Kant, Kennedy assassination, Keynes, Kingsley, Vachel Lindsay, Frank Lloyd Wright, Malinowsky, Ottoline Morrell, Nasser, A S Neill, David Pears, Michael Postan, Schweitzer, Susan Stebbing, several Stracheys, Julian Trevelyan, Trotter of crowd psychology, Voltaire, Alan Wood.
This was the time of the 'Brains Trust', and 'History of Western Philosophy'; up to Russell's Vietnam War Crimes Tribunal. Linguistic philosophy, atomic weapons, Kennedy's assassination, Khrushchev make appearances.
A typical bit of philosophy is: 'Russell is by no means alone in this habit of first assuming that we know certain propositions to be true, and only then enquiring how we know them. This assumption is at the basis of the whole controversy as to whether certain statements can be both synthetic (empirical) and at the same time a priori (i.e. known to be true without experience, as 'Two plus two equals four'..) One of these controversial statements is 'Nothing can be both red and green all over. Yet there seems to be no agreed way of formally demonstrating that it is true in this absolute sense. ..'
If you like Russell, this book gives a good account of the final period of his life, viewed by a sympathetic neighbor.
