To do this we must first clear our minds from the belief that regards our present form of monogamic marriage as ordained by Nature and sanctified by God. He who accepts the development of the love of one man for one woman from other and earlier forms of association may well look forward in faith to a future progress from our existing marriage: yet, though eager for reform, he will, remembering the slowness of this steady upward progress in love's refinement in the past, refrain from acting in haste, understanding the impossibility of forcing any Utopia of the sexes. No change can be made in a matter so intimate as marriage by a mere altering of the law. Only such reforms as are the natural outgrowth of an enlightened public feeling can be of benefit, and thus permanent in their result. I must go further than this and say that what may very possibly be right for the few cannot be regarded as practically moral and good until it can be accepted and acted upon by the people at large. In sex more than in any other department of life we are all linked together; we are our brother's keeper, and the blood of the race will be required at our hands. Many women, and some men, do not realise at all the immense complications of sex and the claims passion makes on many natures. I am sure that this is the explanation of much of the foolish talk that one hears. I tried to make clear in the first chapters of this book the irresistible elemental power of the uncurbed sexual instincts. And this force is at least as strong now as it was in the beginning of life. For in sex we have, as yet, learnt very little. We who are living among the sophistication of aeroplanes, the inheritors of the knowledge of all the ages, have still to pass in wonder along the paths of love, entering into it blindly and making all the old mistakes. Am I, then, afraid that I plead thus for caution? No, I am not. I rest my faith in the development of the racial element in love side by side with its personal ends of physical and spiritual joy. For the sex impulses, which have ruled women and men, will assuredly come to be ruled by them. Just as in the past life has been moulded and carried on by love's selection, acting unconsciously and ignorant of the ends it followed, so in the future the race will be developed and carried onwards by deliberate selection, and the creative energy of love will become the servant of women and men. The mighty dynamic force will then be capable of further and, as yet, unrealised development. This is no vain hope. It has its proof in the past history of the selective power of love. The problems of our individual loves are linked on to the racial life. The hope for improvement rests thus in a growing understanding of the individual's relation to the race, and in an expansion of our knowledge and practice of the high duties love enforces. Let us look now at the practical direction of the present. We have reached these conclusions as a starting-point--
