Thought is based in ignorance, since the motive for engaging in thought is to effect a transition into knowledge. But if thought is based in knowledge, where is the motive? It heads nowhere, because it’s already arrived; and so the mind stays relatively quiet, and uncreative. To think productively, we must find a point of ignorance, and allow it to suffuse our whole mind. Then, as if becoming a child or a student, we may now be taught according to what we see at first as foolishness, and perhaps later as understanding.
