Mr. Pirsig’s plunge into the grand philosophical questions of Western culture remained near the top of the best-seller lists for a decade and helped define the post-hippie 1970s landscape as resoundingly, some critics have said, as Carlos Castaneda’s “The Teachings of Don Juan” helped define the 1960s.
Where “Don Juan” pursued enlightenment in hallucinogenic experience, “Zen” argued for its equal availability in the brain-racking rigors of Reason with a capital R. Years after its publication, it continues to be invoked by famous people when asked to name a book that affected them most deeply — among them the former professional basketball player Phil Jackson, the actors William Shatner and Tim Allen, and the Turkish novelist Orhan Pamuk, a Nobel laureate.
