Derrida uses to to describe how everything that we do is a copy of a copy. We have already said all that we know (63). We all play in a game to try and change around what we already know and re-present it. I think we can only go so far in our own "mastery" or words and knowledge (64). We have said all that we know already so now we are subjected to just twisting and turning what we already know and saying it again.
