This is from Roger Shattuck's The Banquet Years:
Satie, who possessed [a] childlike temperament, was well aware of the effects of his work. He is a humorist as well as a "primitive," and nothing could be more calculated than his waggish directions which he sprinkles through his compositions. ("With profound respect." "Take off your glasses." [-- These as directions for a musician!]) Much of his music builds up a fragile fabric of inanity, and his writings become more and more extreme in their humor. "Why attack God? He is as unhappy as we are. Since his son's death he has no appetite for anything and barely nibbles at his food."
