One of the curious things about our educational system, I would note, is that the better trained you are in a discipline, the less used to dialectical method you're likely to be. In fact, young children are very dialectical; they see everything in motion, in contradictions and transformations. We have to put an immense effort into training kids out of being good dialecticians. Marx wants to recover the intuitive power of the dialectical method and put it to work in understanding how everything is in process, everything is in motion. He doesn't simply talk about labor; he talks about the labor process. Capital is not a thing, but rather a process that exists only in motion. When circulation stops, value disappears and the whole system comes tumbling down.
