Is The Exegesis of Philip K. Dick a bunch of crazy talk?

I hadn't noticed the "crazy talk" comment above. Not sure I understand why you'd use that phrase. Most of what we find in the published Exegesis is quite serious and reasonable exploration of his experiences and the research he was doing into theology/mysticism to understand them, although the experiences and ideas he's working with may be a bit strange. It's of great interest to serious students of religious studies and philosophy as well as literary theory and abnormal psychology. Those of us who have had extraordinary experiences, whether mystical or pathological, find a great deal of insight into these conditions. Frankly, I'm skeptical of the motivations of those who would triivialize or pathologize it. Most of the time when an author's notes are available we are grateful for the opportunity, and little ink is spilled attacking the notes for being in note form.
