Now this, if producible, even though no further moral aim was connected with it, would undoubtedly be of itself a moral element. Suppose two pigs, for instance, had only a single wallowing-place, and each would like naturally to wallow in it for ever. If each pig in turn were to rejoice to make room for his brother, and were consciously to regulate his delight in becoming filthy himself by an equal delight in seeing his brother becoming filthy also, we should doubtless here be in the presence of a certain moral element. And though this, in a human society, might not carry us so far as we require to be carried, it would, without doubt, if producible, carry us a certain way. The question is, Is this moral element, this impassioned and unselfish co-operation with the social law, producible, in the absence of any farther end to which the social law is to be subordinate? The positive school apparently think it is; and this opinion has a seeming foundation in fact. We will therefore carefully examine what this foundation is, and see how far it is really able to support the weight that is laid upon it. That fact, in itself a quite undoubted one, is the possession by man of a certain special and important feeling, which, viewed from its passive side, we call sympathy, and from its active side, benevolence. It exists in various degrees in different people, but to some degree or other it probably exists in all. Most people, for instance, if they hear an amusing story, at once itch to tell it to an appreciative friend; for they find that the amusement, if shared, is doubled. Two epicures together, for the same reason, will enjoy a dinner better than if they each dined singly. In such cases the enjoyment of another plays the part of a reflector, which throws one's own enjoyment back on one. Nor is this all. It is not only true that we often desire others to be pleased with us; we often desire others to be pleased instead of us. For instance, if there be but one easy chair in a room, one man will often give it up to another, and prefer himself to stand, or perhaps sit on the table. To contemplate discomfort is often more annoying than to suffer it. This is the fact in human nature on which the positive school rely for their practical motive power. It is this sympathy and benevolence that is the secret of the social union; and it is by these that the rules of social morality are to be absorbed and attracted into ourselves, and made the directors of all our other impulses.
