LSD is the elixir of the psychedelic 1960s. The substance delights an entire generation and nurtures the hope for a world beyond power and money. However, the counterculture of this time has a deeper layer: behind the colorful, flowery facade lies a cybernetic thinking in feedback loops and control circuits that fuels the imagination. LSD seems to make the theoretical connection between humans and machines a reality. The book tells a different story of the psychedelic movement and shows that the freedom of the hippies also means adapting to technological realities, paving the way into a society of control.
