The proliferation of recorded images undermines our sense of reality. As Susan Sontag observes in her study of photography, “Reality has come to seem more and more like what we are shown by cameras.” We distrust our perceptions until the camera verifies them. Photographic images provide us with the proof of our existence, without which we would find it difficult even to recon­struct a personal history. Bourgeois families in the eighteenth and nineteenth centuries, Sontag points out, posed for portraits in order to proclaim the family’s status, whereas today the family album of photographs verifies the individual’s existence: its docu­mentary record of his development from infancy onward pro­vides him with the only evidence of his life that he recognizes as altogether valid. Among the “many narcissistic uses” that Sontag attributes to the camera, “self-surveillance” ranks among the most important, not only because it provides the technical means of ceaseless self-scrutiny but because it renders the sense of selfhood dependent on the consumption of images of the self, at the same time calling into question the reality of the external world.

By preserving images of the self at various stages of develop­ment, the camera helps to weaken the older idea of development as moral education and to promote a more passive idea according to which development consists of passing through the stages of life at the right time and in the right order. Current fascination with the life cycle embodies an awareness that success in politics or business depends on reaching certain goals on schedule; but it also reflects the ease with which development can be elec­tronically recorded. This brings us to another cultural change that elicits a widespread narcissistic response and, in this case, gives it a philosophical sanction: the emergence of a therapeutic ideology that upholds a normative schedule of psychosocial devel­opment and thus gives further encouragement to anxious self-scrutiny. The ideal of normative development creates the fear that any deviation from the norm has a pathological source. Doc­tors have made a cult of the periodic checkup—an investigation carried out once again by means of cameras and other recording instruments—and have implanted in their clients the notion that health depends on eternal watchfulness and the early detection of symptoms, as verified by medical technology. The client no longer feels physically or psychologically secure until his X-rays confirm a “clean bill of health.”
