This heady illustrated collage is supposedly written by past and future “agents” but is actually authored by Leary himself. Memos addressed to "All Evolutionary Agents on Planet Earth" and Leary's theories of terrestrial and postterrestrial "circuits" guiding human destiny complete the picture.

This vision of a positive, paradisiacal future is one of the most challenging in countercultural thought.
