Madness, then, has a job to do, that is, to conceal our dark secret, so that we have an excuse for failing to live up to our expectations and for setting aside one or more of the tasks of life—working, communing, mating.

You may know him as the world-renowned author of Please Understand Me, Please Understand Me II, and his recent seminal work, Personology.
