In an interview, PKD said this about himself...

"However—if my view that each person has his unique world is correct, then if you say Chinese food is good, in your world it’s good, and if someone else says it’s bad, in his world it’s bad. I’m a complete relativist in that for me the answer to the question “Is Chinese food good or bad?” is semantically meaningless. Now, this is my view. If your view is that this view is incorrect, you might be right. In which case, I would be willing to agree with you."

This is (relativism) pretty much the philosophy of the world in this book, that was established post-nuclear war. And while he admitted?? adopting this way of thinking, he also presented how problematic it can be (obviously) especially when taken to an extreme and in a wider application. Hence, the rise of Jones with his precognition ability and promises of true freedom, exploration, and a revival of the human spirit and love and passion.

Then... lots of other bizarre things happened with multiple storylines woven together really nicely. Is Jones even the center of this novel? I don't know.

A bit of a spoiler ahead but my favorite part was the creation of Venusian mutants. Instead of altering the environment to accommodate earth humans, scientists genetically engineered the human DNA to make them capable of surviving the environment in Venus. Unnatural selection. Basically sped up the process of evolution. A really interesting exploration of this idea.

If you're a PKD fan I'm sure you're already planning on reading lots of his books in your lifetime. Don't miss out on this one.
