Prelude to the Apocalypse

From the introduction to the first edition of Gamma World (1978), describing the events that laid the groundwork for the destruction of human civilization:

Having conquered the rigors of simple survival, man was able to turn his energies to more esoteric considerations – theology, political ideology, social and cultural identification, and development of self-awareness. These pursuits were not harmful in themselves, but it soon became fashionable to identify with and support various leagues, organizations, and so-called "special interest groups." With the passage of time, nearly all of the groups became polarized, each expressing and impressing its views to a degree that bordered on fanaticism. Demonstrations, protests, and debates became the order of the day. Gradually, enthusiasm changed to mania, then to hatred of those who held opposing views. Outbreaks of violence became more frequent, and terrorists spread their views with guns and bombs.
