Never even heard of it. The one Dick novel I possess is
Galactic Pot-Healer, which is quirky and fun (but not shallow). I've read quite a lot of his stuff, but apart from the obvious
Blade Runner and more recent films, I had to check the
quite surprising wikipedia article to remember the titles.
The Man in the High Castle is one of the foremost. It posits an alternate WWII in which Germany and Japan win and partition America, and plays with (I should say, explores seriously) the nature of reality. I recall the
I Ching playing a significant role. Must get hold of it again!
