People think of education as something that they can finish.

Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today - but the core of science fiction, its essence has become crucial to our salvation if we are to be saved at all.

It's just science fiction so it's allowed to be silly, and childish, and stupid. It's just science fiction, so it doesn't have to make sense. It's just science fiction, so you must ask nothing more of it than loud noises and flashing lights.

A good question is, of course, the key by which infinite answers can be educed.

There is not a discovery in science, however revolutionary, however sparkling with insight, that does not arise out of what went before.

The dangers that face the world can, every one of them, be traced back to science. The salvations that may save the world will, every one of them, be traced back to science.

Man's greatest asset is the unsettled mind.
