The duty of a Prophet is to draw a straight line to show how crooked we are. The duty of a satirist is to show how crooked we are by drawing an even more crooked line. Mr. Percy's line is quite crooked.
This book is billed as "the last self help book." He makes his point "sharper than a serpents tooth" in that the entire book is set of multiple-choice quizzes. But, as you suspect, the answers are stacked.
My personal favorite from page 75:
"Question: Why do so many teenagers, and younger people, turn to drugs?"
"(a) Because of peer-group pressure, failure of communication, psychological dysfunction, rebellion against parents, and decline of religious values."
"(b) Because life is difficult, boring, disappointing, and unhappy, and drugs make you feel good."
I found his perspective on suicide, and especially on being an "ex-suicide" to be both novel and fascinating. He asks the question: why not consider suicide as an option? We normally (that is, in the pre-Kevorkian world of 1983 when the book was written) exclude suicide as an option, but Percy makes the point that our depression, angst, etc. may actually have a basis in reality, and we may be justified in pulling our own plug. "Consider the only adults who are not depressed: chuckleheads, California surfers, and fundamentalist Christians . . . Would you trade your depression to become any of these?" (p.76)
By the way, for the Person of Faith who is horrified at this idea of defacing the image of God in suicide, please read (in this order) the book of Lamentations, the book of Ecclesiastes, and then the book of Job. The first two books we routinely ignore, but the last one, Job, we merely talk about and do not read.
