The knowing of the world that is necessarily not in the world is also known as absolute being. You cannot arrive at this as the outcome of any procession of understanding, or according to any logic - it is not an idea, has no 'propositional content' whatsoever. Without it there would be no understanding and understanding is peripherally aware of this dependence without being able to formulate it. In the same way, if it seems to be a kind of knowing, it is also unchanging and so not like any knowing that you recognise. In so far as it is called present, it is constant and unmodified. The only thing that can 'happen' is that understanding, the whole system of understanding, falls silent - and for no reason, simply because it can happen so.
