“Fiction is the evidence that reality exists”

Science-fiction balances you on the cliff. Fantasy shoves you off.

…science fiction is something that could happen – but usually you wouldn’t want it to. Fantasy is something that couldn’t happen – though often you only wish that it could.

The main thing about aliens is that they are alien. They feel no responsibility for fulfilling any of your expectations.

Science fiction is the only literature capable of exploring the macrohistory of our species, and of placing our history, and even our daily lives, in a cosmic context.

If poets are the unacknowledged legislators of the world, science fiction writers are its court jesters. We are Wise Fools who can leap, caper, utter prophecies, and scratch ourselves in public. We can play with Big Ideas because the garish motley of our pulp origins make us seem harmless.

Anything you dream is fiction, and anything you accomplish is science, the whole history of mankind is nothing but science fiction.

The only way of discovering the limits of the possible is to venture a little way past them, into the impossible.
