The Evolutionary Mind: Conversations on Science, Imagination & Spirit (Paperback or Softback)

Stimulating and often startling discussions between three friends, all highly original thinkers: Rupert Sheldrake, controversial biologist, Terence McKenna , psychedelic visionary, and Ralph Abraham , chaos mathematician. Their passion is to break out of paradigms that retard our evolution and to explore new possibilities. Through challenge and synergy they venture where few have gone before, leading their readers on an exciting journey of discovery. Their discussions focus on the evolution of the mind, the role of psychedelics, skepticism, the psychic powers of animals, the structure of time, the life of the heavens, the nature of God, and transformations of consciousness.

“Three fine thinkers take us plunging into the universe of chaos, mind, and spirit. Instead of leaving us lost, they bring us back with startling insights and more wonder than we knew we had.” —Matthew Fox, Original Blessing and Sheer Joy

"A jam-session of the mind, an intellectual movable feast, an on-going conversation that began over twenty years ago and remains as lively and relevant today as it ever was. Sadly, Terence had to leave the conversation a little earlier than planned. But the appearance of this book of trialogues at this critical, historical juncture is a reaffirmation of the potency of the optimistic vision that the trialogues express." —Dennis McKenna, brother of the late Terence McKenna
