Let me say from the outset that my rating in no way reflects that I accept Dick's philosophical/theological ramblings: they are indeed complete nonsense. However, this book was highly entertaining, with the madness of Horselover Fat/Philip Dick taking center stage. The questions raised about Dick's sanity in real life versus the sanity of his avatar in the book are really intriguing. In the end, I think he was a gifted writer who was a bit loony.
