Science fiction is the sovereign prophylactic against future shock.

Each new machine or technique, in a sense, changes all existing machines and techniques, by permitting us to put them together into new combinations. The number of possible combinations rises exponentially as the number of new machines or techniques rises arithmetically. Indeed, each new combination may, itself, be regarded as a new super-machine.

We need a multiplicity of visions, dreams and prophecies - images of potential tomorrows.

Idea-assassins rush forward to kill any new suggestion on the grounds of its impracticality, while defending whatever now exists as practical, no matter how absurd.

Industrial vomit...fills our skies and seas. Pesticides and herbicides filter into our foods. Twisted automobile carcasses, aluminum cans, non-returnable glass bottles and synthetic plastics form immense middens in our midst as more and more of our detritus resists decay.

Our technological powers increase, but the side effects and potential hazards also escalate.
