We know a lot, and we spend a long time trying to find how to say what we know. Really all we need to know is try to find how not to say and how to say "this," "that," and to listen to the music in the after the music is gone, and, after a while, to find how not to say at all. What saying is for I don't know, and I know what saying is for. We say to affirm, we say to bring into being, we say to find each other, we say to find our way, and we say to avoid not saying.
Later: I think I say in order to find how not to say.
