§ 63
For among the dozen or so ductless glands, which Berman[16] has called an “interlocking directorate” of all the human activities, is the interstitial gland which places in circulation in the blood a hormone that vitalizes all the secretions of all the other glands, and which requires for its own perfect working the concomitant and synchronous perfect working of the homologous gland in the mate, in the other demi-human of the complete social unit. In other words perfect physiological health is secured in no better way than by marrying provided marriage is complete marriage and not merely a “Platonic” or business relation.
From these considerations it is evident that as motives for action that leads to happiness, the erotic instincts (if we can succeed in extracting their ore from the mine of our unconscious and refining it from the dross of egoistic-social accretions) are infinitely superior to the egoistic-social.
