“Religion has no business to formulate social laws and insist on the difference between beings, because its aim and end is to obliterate all such fictions and monstrosities.”

Games for Actors and non-Actors (1992)
Context: In truth the Theatre of the Oppressed has no end, because everything which happens in it must extend into life…. The Theatre of the Oppressed is located precisely on the frontier between fiction and reality – and this border must be crossed. If the show starts in fiction, its objective is to become integrated into reality, into life. Now in 1992, when so many certainties have become so many doubts, when so many dreams have withered on exposure to sunlight, and so many hopes have become as many deceptions – now that we are living through times and situations of great perplexity, full of doubts and uncertainties, now more than ever I believe it is time for a theatre which, at its best, will ask the right questions at the right times. Let us be democratic and ask our audiences to tell us their desires, and let us show them alternatives. Let us hope that one day – please, not too far in the future – we’ll be able to convince or force our governments, our leaders, to do the same; to ask their audiences – us – what they should do, so as to make this world a place to live and be happy in – yes, it is possible – rather than just a vast market in which we sell our goods and our souls. Let’s hope. Let’s work for it!

Interview with Weird Tales (24 May 2007) http://weirdtales.net/wordpress/2007/05/24/george-rr-martin-on-magic-vs-science/
Context: I think that for science fiction, fantasy, and even horror to some extent, the differences are skin-deep. I know there are elements in the field, particularly in science fiction, who feel that the differences are very profound, but I do not agree with that analysis. I think for me it is a matter of the furnishings. An elf or an alien may in some ways fulfill the same function, as a literary trope. It’s almost a matter of flavor. The ice cream can be chocolate or it can be strawberry, but it’s still ice cream. The real difference, to my mind, is between romantic fiction, which all these genres are a part of, and mimetic fiction, or naturalistic fiction.

My Disillusionment in Russia (1923)
Context: Its first ethical precept is the identity of means used and aims sought. The ultimate end of all revolutionary social change is to establish the sanctity of human life, the dignity of man, the right of every human being to liberty and wellbeing. Unless this be the essential aim of revolution, violent social changes would have no justification. For external social alterations can be, and have been, accomplished by the normal processes of evolution. Revolution, on the contrary, signifies not mere external change, but internal, basic, fundamental change. That internal change of concepts and ideas, permeating ever-larger social strata, finally culminates in the violent upheaval known as revolution.

De Natura Deorum – On the Nature of the Gods (45 BC)
Variant: For time destroys the fictions of error and opinion, while it confirms the determinations of nature and of truth.
Book II, section 2; translation by Francis Brooks
Variant: Time destroys the figments of the imagination, while confirming the judgments of nature.

Locus interview (2000)
Context: Why do so many people dislike science fiction? The answer goes like this: You have to think of science fiction in contrast to its nearest competitor, heroic fantasy. In heroic fantasy, by and large, things are pretty stable, and then some terrible evil comes along that's going to take over the world. People have to fight it. In the end they win, of course, so the earth is restored to what it was. The status quo comes back. Science fiction's quite different. With science fiction, the world's in some sort of a state, and something awful happens. It may not be evil, it may be good or neutral, just an accident. Whatever they do in the novel, at the end the world is changed forever. That's the difference between the two genres — and it's an almighty difference! And the truth is science fiction, because we all live in a world that's changed forever. It's never going to go back to what it was in the '60s or the '70s or the '30s, or whatever. It's changed.
