"Sometimes I think I am going mad. I live for days in the mystery and tears of things so that the commonest object, the most familiar face- even my own- become ghostly, unreal, enigmatic. I get into an attitude of almost total scepticism, nescience, solipsism, in a world of dumb, sphinx-like things that cannot explain themselves. The discovery of how I am situated- a sentient being on a globe in space overshadows me. I wish I were just nothing."
