Written in 1972, which is the mid-to-late point of Fuller's writing timeline. Because of the way the book is printed (short lines, wide margins), one can read this book quickly. I wish the book spent more time on the concept of using comprehensive and anticipatory design science to distribute and effectively use resources in such a way that all humanity benefits, to the point of what Fuller describes as "the end of humanity's wants," which would in his opinion effectively end war. My favorite line, to this point, of the book was "For now we know scientifically that wealth consists exclusively of physical energy which cannot be depleted, plus intelligence's know-how, which can only increase."
