And if I don’t ever say what must be done, it isn’t because I believe that there’s nothing to be done; on the contrary, it is because I think that there are a thousand things to do, to invent, to forge, on the part of those who, recognizing the relations of power in which they’re implicated, have decided to resist or escape them. From this point of view all of my investigations rest on a postulate of absolute optimism. I do not conduct my analyses in order to say: this is how things are, look how trapped you are. I say certain things only to the extent which I see them as capable of permitting the transformation of reality.
