"The Exegesis" is a posthumously published work by Philip K. Dick, which is a compilation of his personal writings, notes, and philosophical musings on the nature of reality, religion, and metaphysics. The book is based on a series of journal entries that Dick wrote in the early 1970s, which he referred to as his "Valis" experiences.
In these writings, Dick discusses his belief that he had been contacted by a higher intelligence, which he called VALIS (Vast Active Living Intelligence System), and that this intelligence was communicating with him through a series of mystical experiences, visions, and dreams. He also explores his fascination with Gnosticism, a set of early Christian beliefs that emphasize the pursuit of knowledge and the rejection of materialism.
Throughout the book, Dick grapples with his own mental health issues, including bouts of paranoia and delusions, which he believed were related to his experiences with VALIS. He also expresses his frustrations with the mainstream scientific and religious establishments, which he saw as limiting and narrow-minded.
"The Exegesis" offers a unique insight into the mind of one of the most visionary and influential science fiction writers of the 20th century, and provides a fascinating glimpse into the personal struggles and philosophical questions that informed much of his work
