To be present to himself, man must find the presence of another or others. Man's life-world is the opposite of solipsist: it is a world not of presence but of presences. In presences we mature. Each individual I finds himself by dealing with a thou, and another thou, and another. The presence of other persons fills man's consciousness, as objects cannot. Situated among objects, a person may indeed find them interesting, but he responds only other persons, other presences, who are not objects. In a whole universe filled with countless objects and occupied only by one other man alone, it would be to the man alone that I could present myself, establish a relationship of presence.
