I am not sure that we disagree.
Zen is among my top three all-time favorite books. (my screen name gives away my #1)
But Pirsig's convoluted exploration of Quality is, while brilliant, difficult to read.
Odd little book - either hated or loved.
then I misunderstood you, sorry.
I found the "pursuit of quality" an interesting take on how one may choose to live a life, and how a single-minded pursuit of things unknowable can lead to madness. That I can identify a bit with this madness is why I re-read it periodically.
Also, it led to some very interesting debates with philosophy professors in college, usually ending with their anger as I tried to raise basic issues of thought and logic from ancient Greeks, while they were pushing Nietsche and the like.
I never got into much science fiction, but a few authors strike my fancy. I like Neal Stephenson's Crytonomicon and Snow Crash, but the Baroque Cycle lost me.
