Lost in the Cosmos by Walker Percy

Different than anything I have ever read and dealing with a difficult, elusive topic - the self. Keeping you constantly off balance and always going too far, you are nonetheless caught by the importance of the subject, the great difficulty of any ordinary approach to discussing the self, and a great reluctance to admit that the author is onto something. Indeed he forces you to make a great many "points" against your will and dutifully pay him homage for causing you to think about the part of you that thinks and to analyze the analyzer and de-costume the actor.
