Yet not alone the visually perceptible reactions. For there are reactions of every variety. If you have ever used a blow pipe on a piece of copper, and observed the iridescence which soon comes, you will realize the same beauties in every sense preceding the complete annealing of your wife by the heat of passion you engender in her. If you have ever watched the iridescence of a spraying fountain in the sun, you will see the same effect in the emotions of your wife when the relaxation of tension has broken up her being into fine particles that float slowly down and refract the light rays of your love. And the beauty and calm of the rainbow after a summer storm is nothing to that of the mental state of a woman after the downpour of her erotic passion. All these are features to which the anesthetic man is insensible. Although the similes used are visual, there is not a sense quality that cannot be thrilled by the perception of the woman’s reactions. And although the similes rather hint at the finale than at the preliminaries they all refer to the effect produced on the woman by the activities of the man. The kinesthetic sense of the husband must be developed. He is much wiser if he will give these sensations some appreciative study. It will help to give him control by taking his mind off the burden of tension he has to carry himself, and enable him to acquire over his wife that domination in the exclusively erotic sphere which is essential not only to his wife’s happiness but to his own. § 141 Anesthesia is love-blindness. Love is pictured blind because he does not see _defects_. The worst blindness of love is its not seeing beauties. Most husbands’ love is blind. This is the anesthesia meant. When one is given surgically an anesthetic it is to make one insensible to pain. Love anesthesia is the insensibility to the love emotions which are stirred in every man by every woman. Can a man be aware of these appeals, made by every woman, and choose to remain true to the woman he has married? What good would be done to him if the anesthetic to which, by virtue of conventional repression, we are all subject, should be suddenly removed? Would not such a man be irresistibly impelled to make love to any and every woman he saw? Where then would monogamy be? But if monogamy depended on anesthetics of this type it would be on a very insecure basis. It would not endure a week. Yet most men are love-blind, are anesthetic to woman’s deepest erotic appeal. Furthermore the securest protection for monogamy is the removal of that anesthesia. § 142 This doctrine of the supremity of masculine erotic control will be objected to, and by the best of women. They will say that they get their joy in perfect marriage from the knowledge that their husbands are made happy. They will also say that it is only fair play if there is a give and take on both sides, and that the denial of woman’s control relegates them to an inferior position.
