I first read Zen and the Art of Motorcycle Maintenance when I was about 14. That is a very impressionable age to come across something like ZAMM. I remember I read it through twice one after the other, something I don't think I have ever done with any other book.
I have often wondered if this was the book that caused me to study philosophy at University. Possibly, but it may also have been Lisa Alther's Kinflicks that did that. Whatever. . . .
Robert Pirsig passed away a few days ago. And to have written something like ZAMM is to have achieved an immense thing.
I have four books that I read at the rate of one a year in rotation. 2017 was a year to read The Dharma Bums, and next year was supposed to be The Snow Leopard, before reading ZAMM in 2019. But maybe a re-order is called for.
