From this point of view, then, we cannot extend the proposition that love is an end in itself so far as to say that _it may remain unfruitful_. It must give life; if not new living beings then new values; it must enrich the lovers themselves and through them mankind. Here as everywhere the truth which gives faith in life and creates morality is to be found included in the experience which creates happiness; and the most serious charge against certain forms of “free love” is that it is unhappy love; for there is no unhappy love but the unfruitful. The capacity of mankind for forgetting is more wonderful than its capacity for learning. If this were not so, there would be no necessity to recall again and again that every band of apostles includes a Judas; nay, that the truth can only be accepted by disciples in the hands of its enemies. One is reminded by this that every reformation has its visionaries who arrest the blow when the reformers have put their axe to the root of the tree; and one is not surprised that with every spring flood not only the ice but the earth itself is washed away. Mankind seems determined not to remember. They must therefore be reminded once more that the new morality’s band of combatants, ever more closely united and more rapidly increasing, are distinguished from their scattered followers and from their light advance-guard by the knowledge that _love is subject to the same law as every other creative force; the law of dependence on the whole for its own enhancement to its highest possible value_. Love, indeed, whose origin is the very instinct of the race, must be more deeply bound up with the race than any other emotion. And experience shows too that it cannot preserve and promote its vital force if it lacks any connection with, and does not stand in some relation, either of giving or receiving, to the race. It is therefore an indisputable necessity that every love entirely detached from the rest of humanity must die for want of nourishment. But the band which attaches it to humanity may be woven of several materials; the gift to the race may express itself in various ways. In one case a great emotion may bring about a tragic fate, which opens the eyes of humanity to the red abysses it contains within itself. Another time it may create a great happiness, which sheds a radiance around the happy ones, illuminating all who come near them. In many cases love translates itself into intellectual achievements, or useful social work; in most it results in two more perfect human beings, and new creatures, still more perfect than themselves.
