Zen and the Art of Motorcycle Maintenance, by Robert M. PirsigRead about another entry on the list.
Clinically depressed and diagnosed with paranoid schizophrenia at a young age, Pirsig had several mental breakdowns over the course of his life and was in treatment almost continuously. Whether or not this compromises the value of his Metaphysics of Quality laid out and explored in seminal book Zen and the Art of Motorcycle Maintenance is up to the reader.
Zen and the Art of Motorcycle Maintenance appears on the Telegraph's critics' list of the fifty best cult books, Michael Palin's six best books list, John Mullan's list of ten of the best motorbikes in literature, and Sebastian Beaumont's top ten list of books about psychological journeys.
