In these collected essays, Timothy Leary explains his belief that humans are morphing into space beings. He describes eight circuits of human metamorphosis, analyzing in depth the consciousness and its purpose manifested by each change. Fifteen chapters cover a range of topics from Spinning Up the Genetic Highway to Neurogeography of Terrestrial Politics to Twelve Stages of Post-Cultural Evolution. In each of these insightful pieces the author describes the complicated psychological metamorphosis that precedes the launch of humans into space beings. This collection of Learys early work at his imaginative and provocative best had an enormous impact on psychology and the humanist movement.
