In marriage, more than one husband thinks he ought to be separated from his wife and children so as not to spoil them. There is no need of a long explanation to show the fallacy of this idea. To be complete, love should be reciprocal, and to remain mutual it requires mutual education in marriage. Every husband should above all be separated from himself, and not from his wife. If each one did all in his power to promote the happiness of the other, this altruistic effort would strengthen his own sentiments of sympathy. This requires a constant and loyal effort on each side, but it avoids the illusion of a false love, provoked by the senses, vanishing like smoke or becoming changed to hatred. Without being blind to the weaknesses of his partner he must learn to like them as forming part of the person to whom he has devoted his heart, and employ all his skill in correcting them by affection, instead of increasing his own weakness by leaning on them. It is necessary, therefore, neither to admire nor to dislike the defects of the loved one, but to try and attenuate them by aid of integral love. Love has been defined as "dual egoism." The reciprocal adulation of two human beings easily degenerates into egoistic enmity toward the rest of the human race, and this often reacts harmfully on the quality of love. Human solidarity is too great, especially at the present day, for such exclusivism in love not to suffer. I would define ideal love as follows: _After mature consideration, a man and a woman are led by sexual attraction, combined with harmony of character, to form a union in which they stimulate each other to social work, commencing this work with their mutual education and that of their children._ Such a conception of love refines this sentiment and purifies it to such an extent that it loses all its pettiness, and it is pettiness which so often causes it to degenerate, even in its most loyal forms. The social work in common of a man and woman united by true affection, full of tenderness and devotion for one another, mutually encouraging each other to perseverance and to action, will easily triumph over petty jealousies and all other instinctive reactions of the phylogenetic exclusiveness of natural love. The sentiments of love will thus become ever more ideal, and will no longer provide egoism with the soil of idleness and comfort on which it grows like a weed.
