Trialogue between Terence McKenna, Ralph Abraham, and Rupert Sheldrake.
Recorded in Hazelwood, Devon, England, June 1993.
'How do homing pigeons find their way home? All theories attempting to explain this phenomenon have failed. More unexplained biological mysteries. Do animals and humans have senses or powers unacknowledged by science? What are the implications of these powers? Rupert's proposed experiment with a mobile pigeon loft. Pigeon racing. Ralph's visual theory and the elastic band theory. A quantum mechanical perspective on these forces. Why have humans lost contact with such powers? New domains of quantum mechanical biology. To what degree is the assumption that the future is unknowable an artefact of culture and language?'
