Who is Maurice from Valis and what is their importance?

Maurice is Horselover Fat's last therapist, he helps him cope with his divorce from Beth. A product of the 1960s, Maurice is a member of SNCC and CORE. He is also a former Israeli commando. His main plan is to bully Fat into enjoying life instead of saving people. If he wants to help people, Maurice says, Fat should give money to professional care-givers rather than trying, amateurishly, to help himself. When Fat reveals his views on religion, Maurice is shocked and demands that he read Genesis and prioritize its themes. As a Jew, Maurice cannot understand how religion and ethics can be separated. Maurice's emotional assault on Fat destroys the self-image that Dr. Stone worked so hard to build up.
