The human ideal requires that they shall not do to others what they would not think it just that others should do to them; yet they seduce maidens, make them mothers, and abandon them without caring about the children born of these unions; without caring whether the young mother commits suicide, dies of grief, or becomes depraved; without caring whether the parents go down to the grave. Like deadly reptiles, they glide to the domestic fireside of others, rob their friend of the affection of his wife, and force him to labor for the children of adultery. The woman who believes in irrepressible love breaks her pledges to her husband; lives a life of deceit; brings trouble and sorrow into the houses of other women, whose lives are blighted by her. It is in this way that those who practice this sophistry fulfil their duty to be just, not to afflict their fellows, to labor for the happiness and improvement of those about them, to preserve the weak from oppression and wrong. To this pretended irrepressibility of love, they sacrifice Justice, goodness, the happiness, repose and honor of others; lead them into the path of dissipation; bring dissolution into the family and society; in a word, offer up as a sacrifice to animal instinct, moral sense and reason. You have also been told that every species of love is found in Nature; the polyamic and polygandric, as well as that of the constant pair. Yes, my child, every species of love is found in Nature, as is every species of vice and every species of virtue. But you know that it is not enough that a thing exists within us to prove it to be good; it must be in conformity with the ideal of our destiny, with our harmony: it is wrong in the opposite case. Love, such as we have defined it, needs duration and equality; duration, because we do not become modified in a few months; because we do not accomplish great works in a few months; because we do not rear children in a few months; duration is so truly an aspiration of love, that it imagines that eternity will hardly suffice for it. It must have equality; division is hateful to it; it will therefore have a unit for a unit, both male and female. Now polygamy and polyandria are the negation of equality, of dignity in love. Let us consider the effects of these two deviations of instinct.
