Maybe my favorite PKD novel. Visionary, philosophical, humorous, page-turning, and all probably banged out in a matter of days, while on speed! I was especially amused by the Rick & Iran's constant fretting over what mood settings to use on themselves via the "mood organ". I liked the way the digressions, and side-plots combined with the main plot. So much of this book is very relevant even in 2019, especially Isadore's musings about "kipple" and "kipplization". I feel the "mercerist" attitude towards the animals of the world is still a little ways off into our future. Finally, it's hard to imagine how they got to Blade Runner from this source material.
