At the beginning of 1914 he came to me in a state of great agitation and said : 'I am leaving Cambridge, I am leaving Cambridge at once.' 'Why?' I asked. 'Because my brother-in-law has come to live in London, and I can't bear to be so near him.' So he spent the rest of the winter in the far north of Noray. In early days I once asked G. E. Moore what he thought of Wittgenstein. 'I think very well of him', he said. I asked why, and he replied: 'Because at my lectures he looks puzzled, and nobody else ever looks puzzled.'
