I have read Zen and Lila.
Zen was an “Inquiry Into Values”.
Lila was an “Inquiry Into Morals”.
He tried hard to discover a way for man to be good without God.
He gave it a noble try, but he wasn’t successful.
There are many gems in his books. I enjoy his chapter on meeting Robert Redford. Redford wanted to make a movie out of Zen. Pirsig wouldn’t sell him the rights.
He was a very good thinker and communicator.
I come back to "Lila" occasionally to think about it, but I haven't re-read it yet.
