You can’t crush ideas by suppressing them. You can only crush them by ignoring them. By refusing to think, refusing to change.

Science fiction - and the correct shortcut is 'sf' - uses actual scientific facts or theories for the source ideas or framework of the story. It has some scientific content, however speculative. If it breaks a law of physics, it knows it's doing so and follows up the consequences. If it invents a society of aliens, it does so with some respect for and knowledge of the social sciences and what you might call social probabilities. And some of it is literarily self-aware enough to treat its metaphors as metaphors.

I doubt that the imagination can be suppressed. If you truly eradicated it in a child, he would grow up to be an eggplant.

If you deny any affinity with another person or kind of person, if you declare it to be wholly different from yourself - as men have done to women, and class has done to class, and nation has done to nation - you may hate it or deify it; but in either case you have denied its spiritual equality and its human reality. You have made it into a thing, to which the only possible relationship is a power relationship. And thus you have fatally impoverished your own reality.

A man would know the end he goes to, but he cannot know it if he does not turn, and return to his beginning, and hold that beginning in his being. If he would not be a stick whirled and whelmed in the stream, he must be the stream itself, all of it, from its spring to its sinking in the sea.

The machine conceals the machinations.
