Certainly it may, under present imperfect conditions, often be a duty not to destroy the outward form of marriage for the sake of the children. But by no means can this duty be preached as universally binding. Only the individual himself can in each separate case determine the dissolution best, both for the children and for the married couple themselves, of a marriage which has fallen asunder within. When we consider the development in its entirety, the sooner people cease to sanction the present marriage the more fortunate it will be; for the sooner will the transformation be forced upon us by which marriage will maintain its permanence only from within. Only then will man be wholly able to have the experiences and to find the new, delicate means by which fidelity can be strengthened and happiness assured. But man will not seek this expedient so long as he can rely upon the power of legal right and social opinion to hold together that which love does not unify. The ever increasing individualization of love indicates that mono-marriage will doubtless remain the form of erotic union between man and woman. But this rule will have, in the future, as in the past, many exceptions, since the feelings can change. The conflicts which will thus arise will bring suffering as a consequence, but not the bitterness nor the contention which the property sense in marriage now so often occasions. The deep consciousness that love belongs not to the sphere of duty but only to that of freedom will cause the one who has lost the love of the other to feel the same resignation before the inevitable, as if he were separated from the other by death. And in cases where the individual is not capable of this resignation, then the law as well as custom shall make it impossible for the one to hold back the other against his will. Each of the twain shall be master of his own person and of his property, of his work and of his mode of life; the union shall in each especial case be arranged by the agreement of the individuals, and the law shall decide only the rights and duties of the husband and wife in regard to the children. When in this way it shall come to pass that neither the husband nor wife shall have in outward sense, in external things, anything to gain or to lose by the consummation or dissolution of marriage, then only the erotic problem appears in all its seriousness.
