As its best, SF is the medium in which our miserable certainty that tomorrow will be different from today in ways we cant predict, can be transmuted to a sense of excitement and anticipation, occasionally evolving into awe. Poised between intransigent scepticism and uncritical credulity, it is par excellence the literature of the open mind.
John BrunnerExtremism. It is an almost infallible sign โ a kind of death-rattle โ when a human institution is forced by its members into stressing those and only those factors which are identificatory, at the expense of others which it necessarily shares with competing institutions because human beings belong to all of them.
