Nor does the new morality deny to the many, who have not even been capable of dreaming of personal love, the right to contract a marriage, which will at least contribute to their poor existence the interest of home and the joy of parentage. But it will be severe with those who, having had experience or intuition of love, have entered without it into a marriage which will certainly impoverish and perhaps ruin more lives than their own. Prudence may counsel leniency of judgment in the individual case, since the majority of human beings learn to know their hearts late in life, if at all. Once more, _as a guiding principle of morality, the unity of marriage and love must be maintained_. By his power of creating ideals, and the ever-increasing demand for happiness which results, man has deepened his instinct of spiritual needs, and the same power of idealisation is now ruthlessly withdrawing the outward supports of sexual morality and replacing them by the idea of unity. That the halt and the lame are thereby deprived of their crutches will be no stumbling-block to him who looks beyond the halt and the lame to the finer and healthier men of the future. It is true that the idea of unity involves the right of every person to shape his sexual life in accordance with his individual needs, but only on condition that he does not prejudice unity or the rights of the beings to whom his love gives life. _Love thus becomes more and more a private affair of the individual, while children are more and more the business of society_, and from this it follows that the two lowest expressions of sexual division (dualism) sanctioned by society, namely, _coercive marriage and prostitution, will by degrees become impossible, since after the triumph of the idea of unity they will no longer answer to the needs of humanity_.
