I read a page of Plato's great work. I can no longer understand anything, because behind the words on the page, which have their own heavenly brightness, to be sure, there shines an even brighter, an enormous, dazzling -why- that blots out everything, cancels out, destroys all meaning. All individual intelligence. When one has understood, one stops, satisfied with what one has understood. I do not understand. Understanding is far too little. To have understood is to be fixed, immobilized. It is as though one wanted to stop on one step in the middle of a staircase, or with one foot in the void and the other on the endless stair. But a mere why, a new why can set one off again, can unpetrify what was petrified and everything starts flowing afresh. How can one understand? One cannot.
