"Zen and the Art of Motorcycle Maintenance: an Inquiry into Values by Robert M Pirsig (1974)
Burnt-out hippy takes son on bike trip. Remembers previous self: lecturer who had nervous breakdown contemplating Eastern and Western philosophy. Very bad course in Ordinary General Philosophy follows. If he’d done Greek at school and knew what "arête" meant, we could have been spared most of the 1970s. AMcK"
"The Celestine Prophecy by James Redfield (1993)
Deep in the South American jungle an intrepid explorer is about to stumble on a sequence of ancient prophecies that could change our way of living, even save the world. If only we didn’t have to buy the other novels in that the series to find out what they were! For a similar effect on the cheap, rent an Indiana-Jonesalike film – Tomb Raider, say – and ask a hippy to whisper nonsense in your ear while you're watching it. TM"
