I see that Robert Pirsig, author of Zen and the Art of Motorcycle Maintenance, passed away yesterday. I ran across this book at a friend's house where I was staying way back in the 70s. I like to read in bed before I go to sleep and I picked this up off the shelf because of the unusual title. But I ended up reading the entire book instead of sleeping! Years later I read it again a couple of times. I was just thinking a couple of weeks ago that I was due to read it again. This is a profoundly unusual book. The idea of the title has been copied many times, but the idea of the book has not. It is as much about Plato as it is about Zen. And it is as much about life and psychology as it is about philosophy. I recommend it highly.
