The late Walker Percy's mordant contribution to the self-help book craze of the 1980s deals with the heavy abstraction of the Western mind and speculates about why writers may be the most abstracted and least grounded of all. (Before taking up novel writing, Percy was a medical doctor who became a patient in the very institution where he had worked.) The book disappeared for a time. Now it's back in print. Take the quizzes in it, then take a walk--you need to be back in the world before you write another word.
