Desire has no history - at least, it is experienced in each instance as all foreground, immediacy. It is aroused by archetypes and is, in that sense, abstract. But moral feelings are embedded in history, whose personae are concrete, whose situations are always specific. Thus, almost opposite rules hold true for the use of the photograph to awaken desire and to awaken conscience. The images that mobilize conscience are always linked to a given historical situation....Photograph cannot create a moral position, but they can reinforce one - and can help build a nascent one.
