The theme of depersonalization (being “taken over”) which I have been talking about is a new allegory reflecting the age-old awareness of man that, sane, he is always perilously close to insanity and unreason. But there is something more here than just a recent, popular image which expresses man’s perennial, but largely unconscious, anxiety about his sanity. The image derives most of its power from a supplementary and historical anxiety, also not experienced consciously by most people, about the depersonalizing conditions of modern urban life.
