Life is to be fortified by many friendships. To love, and to be loved, is the greatest happiness of existence. If I lived under the burning sun of the equator, it would be a pleasure to me to think that there were many human beings on the other side of the world who regarded and respected me; I could and would not live if I were alone upon the earth, and cut off from the remembrance of my fellow-creatures. It is not that a man has occasion often to fall back upon the kindness of his friends; perhaps he may never experience the necessity of doing so; but we are governed by our imaginations, and they stand there as a solid and impregnable bulwark against all the evils of life.
