Most of the film is a sequence of set pieces of individuals espousing a pop-philosophy to the passive protagonist; there isn't a single consistent Weltanschauung expressed, more a gallop through modern Californian-style theories on the nature of consciousness and being. Tim Leary and Phillip K. Dick are both explicitly mentioned, and are very much of the genre.
Overall though, I found myself feeling like I was on a particularly vigorous fairground ride; simultaneously enjoying the experience but hoping it would stop soon. The continuous onslaught of interesting but unchallenged and unexamined philosophical monologues got to me after a while, and I wanted things to slow down.
