Robert Maynard Pirsig (September 6, 1928 – April 24, 2017) was an American writer and philosopher. He was the author of the philosophical novels Zen and the Art of Motorcycle Maintenance: An Inquiry into Values (1974) and Lila: An Inquiry into Morals (1991)

The better known, Zen and the Art of Motorcycle Maintenance, develops around Pirsig's exploration into the nature of "Quality". It is an exploration of the underlying metaphysics of Western culture. Pirsig finds in "Quality" a special significance and common ground between Western and Eastern world views.

In Lila: An Inquiry into Morals, he developed a value-based metaphysics, Metaphysics of Quality, that challenges our subject-object view of reality
