Medicine labours to restore 'natural' structure or 'normal' function. But greed, egoism, self-deception,and self-pity are not abnormal in the same sense as astigmatism or a floating kidney. For who, in Heaven's name, would describe as natural or normal any man from whom these failings were wholly absent? 'Natural,' if you like, in a quite different sense; archnatural, unfallen. We have only seen one such Man. And he was not at all like the psychologist's picture of the integrated, balanced, adjusted, happily married, employed, popular citizen. You can't really be 'well adjusted' to your world if it says 'you havea devil' and ends by nailing you up naked to a stake of wood.
