What is the cause, though, of the growth of an acorn? The oak that is to come! What is to happen in the future is then the cause of what is occurring now; and, at the same time, what occurred in the past is also the cause of what is happening now. In addition, a great number of things round about, on every side, are causing what is happening now. Everything, all the time, is causing everything else
