On the Theory of Knowledge, Theory of Progress [N2a,3]

It’s not that what is past casts its light on what is present, or what is present its light on what is past; rather, image is that wherein what has been comes together in a flash with the now to form a constellation. In other words, image is dialectics at a standstill. For while the relation of the present to the past is a purely temporal, continuous one, the relation of what-has-been to the now is dialectical: is not progression but image, suddenly emergent. — only dialectical images are genuine images (that is, not archaic); and the place where one encounters them is language. ◊Dream City and Dream House, Dreams of the Future, Anthropological Nihilism, Jung◊
