“Why, M. Bloch, is there a change in the weather; has it been raining? I can’t understand it; the barometer has been ‘set fair.’” Which drew from Bloch nothing more instructive than “Sir, I am absolutely incapable of telling you whether it has rained. I live so resolutely apart from physical contingencies that my senses no longer trouble to inform me of them.” “My poor boy,” said my father after Bloch had gone, “your friend is out of his mind. Why, he couldn’t even tell me what the weather was like. As if there could be anything more interesting! He is an imbecile.”
