Spider Robinson Quote

I think of us as a people who inoculate ourselves against a plague of insanity with a powerful anti-idiotic called science fiction. I think sf is a literature which by its very nature requires that you be at least a little sane, that you know at least a little something. You must abdicate the right to be ignorant in order to enjoy science fiction, which most people are unwilling to do; and you must learn, if not actually how to think things through, at least what the trick looks like when it's done. Frequent injections will keep a lot of madness away.
