In its psychic manifestation this intense sex-distinction is equally apparent. The primal instinct of sex-attraction has developed under social forces into a conscious passion of enormous power, a deep and lifelong devotion, overwhelming in its force. This is excessive in both sexes, but more so in women than in men,—not so commonly in its simple physical form, but in the unreasoning intensity of emotion that refuses all guidance, and drives those possessed by it to risk every other good for this one end. It is not at first sight easy, and it may seem an irreverent and thankless task, to discriminate here between what is good in the “master passion” and what is evil, and especially to claim for one sex more of this feeling than for the other; but such discrimination can be made. It is good for the individual and for the race to have developed such a degree of passionate and permanent love as shall best promote the happiness of individuals and the reproduction of species. It is not good for the race or for the individual that this feeling should have become so intense as to override all other human faculties, to make a mock of the accumulated wisdom of the ages, the stored power of the will; to drive the individual—against his own plain conviction—into a union sure to result in evil, or to hold the individual helpless in such an evil union, when made. Such is the condition of humanity, involving most evil results to its offspring and to its own happiness. And, while in men the immediate dominating force of the passion may be more conspicuous, it is in women that it holds more universal sway. For the man has other powers and faculties in full use, whereby to break loose from the force of this; and the woman, specially modified to sex and denied racial activity, pours her whole life into her love, and, if injured here, she is injured irretrievably. With him it is frequently light and transient, and, when most intense, often most transient. With her it is a deep, all-absorbing force, under the action of which she will renounce all that life offers, take any risk, face any hardships, bear any pain. It is maintained in her in the face of a lifetime of neglect and abuse. The common instance of the police court trials—the woman cruelly abused who will not testify against her husband—shows this. This devotion, carried to such a degree as to lead to the mismating of individuals with its personal and social injury, is an excessive sex-distinction.
