I realize now that my walks, whether taken to pass the time or to better acquaint myself with a foreign city, or conducted in a hurry—to post a letter, to catch a train or on the occasion I was late for an appointment—all took place under the vague suspicion that I might somehow come upon myself, that is to say, that other self who lives in harmony with his surroundings, who exists, like a chapter in a book, in the right place, not torn out and left to make sense on its own.
