My friend Debra just loaned me The Principles of Uncertainty, by Maira Kalman. I think you would dig this book, Bill, both the art and the musings.

Here's a link to one chapter of the book, which was originally a series of visual pieces published by the NY Times. Here's a link to an interview with her about her art practice. I wish she were my friend. I almost wish that I wore hats, just because she is so excited by them and the people who have the insouciance, self-confidence, and imagination wear them.
