For a long time, I felt instinctively irritated - sometimes repelled - by scientific friends' automatic use of the word 'mechanism' for automatic bodily processes. A machine was man-made; it was not a sentient being; a man was not a machine.
I sort of mind living in a time when most of the literature is terribly personal. I suppose it's because I grew up on a love of history, philosophy, science and religion, but not to think too much about yourself.
