“If a person loves only one other person and is indifferent to the rest of his fellow men, his love is not love but a symbiotic attachment, or an
enlarged egotism. Yet most people believe that love is constituted by the object, not by the faculty. In fact, they even believe that it is proof of the intensity of their love when they do not love anybody except the "loved" person. This is the same fallacy which I have already mentioned above. Because one does not see that love is an activity, a power of the soul, one believes that all that is necessary to find is the right object - and that everything goes by itself afterward. This attitude can be compared to that of the man who wants to paint but who, instead of learning the art, claims that he just has to wait for the right object - and that he will paint beautifully when he finds it. If I truly love one person I love all persons, I love the world, I love life. If I can say to somebody else, "I love you," I must be able to say, "I love in you everybody, I love through you the world, I love in you also myself.”
