Excerpts from Walter Benjamin, N Convolutes (c. 1928-1940):

What distinguishes images from the “essences” of phenomenology is their historical index. (Heidegger seeks in vain to rescue history for phenomenology abstractly through “historicity!’)’ These images are to be thought of entirely apart from the categories of the “human sciences,” from so-called habitus, from style, and the like. For the historical index of the images not only says that they belong to a particular time; it says, above all, that they attain to legibility only at a particular time. And, indeed, this acceding “to legibility” constitutes a specific critical point in the movement at their interior. Every present day is determined by the images that are synchronic with it: each “now” is the now of a particular recognizability. In it, truth is charged to the bursting point with time. (This point of explosion, and nothing else, is the death of the intentio, which thus coincides with the birth of authentic historical time, the time of truth.) It is 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 purely temporal, the relation of what-has-been to the now is dialectical: not temporal in nature but figural. Only dialectical images are genuinely historical—that is, not archaic­ images. The image that is read—which is to say, the image in the now of its recognizability—bears to the highest degree the imprint of the perilous critical moment on which all reading is founded. [N3,1]

Is awakening perhaps the synthesis of dream consciousness (as thesis) and waking consciousness (as antithesis)? Then the moment of awakening would be identical with the “now of recognizability;” in which things put on their true­ surrealist-face. Thus, in Proust, the importance of staking an entire life on life’s supremely dialectical point of rupture: awakening. Proust begins with an evocation of the space of someone waking up. [N3a,3]

In the dialectical image, what has been within a particular epoch is always, simultaneously, “what has been from time immemorial.” As such, however, it is manifest, on each occasion, only to a quite specific epoch—namely, the one in which humanity, rubbing its eyes, recognizes just this particular dream image as such. It is at this moment that the historian takes up, with regard to that image, the task of dream interpretation. [N4,1]

Just as Proust begins the story of his life with an awakening, so must every presentation of history begin with awakening; in fact, it should treat of nothing else. This one, accordingly, deals with awakening from the nineteenth century. [N4,3]

All historical knowledge can be represented in the image of balanced scales, one tray of which is weighted with what has been and the other with knowledge of what is present. Whereas on the first the facts assembled can never be too humble or too numerous, on the second there can be only a few heavy, massive weights. [N6,5]

The fore- and after-history of a historical phenomenon show up in the phenomenon itself on the strength of its dialectical presentation. What is more: every dialectically presented historical circumstance polarizes itself and becomes a force field in which the confrontation between its fore-history and after-history is played out. It becomes such a field insofar as the present instant interpenetrates it. And thus the historical evidence polarizes into fore- and after-his­ tory always anew, never in the same way. And it does so at a distance from its own existence, in the present instant itself—like a line which, divided according to the Apollonian section, experiences its partition from outside itself.

Telescoping of the past through the present. [N7a,3]
