Annihilation and Utopia [PDF ebook] 

Originally published in 1966. The main purpose of this book is not philosophical speculation, but to draw the obvious conclusions from political and historical facts about the prospects and methods of human political survival. The central theme is developed in the context of problems which cause most anxiety today: the mounting arms race, the unstable balance of power, the rapid growth of population, racial conflicts and ideological incompatibilities.
