The sequel of such coalescence of the sexes, or marriage legitimately considered, is copulation and reproduction of the species. The summit, or peripheral center of venereal sensibility, is found at the genitalia, and in the male a concentration of nerve-force conducts, as it were, to and unites at the glans penis; and division of the terminal nerves at this point will render erection impossible. In both man and beast, the only mechanical irritation capable of exciting venereal sensibility must be at this point. When the sexual centers are physiologically irritated, from peripheral or centric influences, contentment is only possible (physiologically speaking) when male and female counterparts coalesce, or are in juxtaposition. The sexual attributes also constitute an instructive topic for study, as they become modified by civilization and the development of reason. The procreation of organic life is the sequel of the sexual connection. The living universe has been called into existence, and the perpetuation of its life-spark is only dependent upon the contact of sexes. The universe, it is said by one theorist, was evolved; by another, who depends upon the Holy Book for a guide, all living creatures were thaumaturgically or miraculously, and “in the twinkling of an eye,” made to exist in full form and shape. This problem will never be settled to the satisfaction of all men as long as theory and faith are at war; and small is the prospect of peace while both parties are redoubling in their forces annually. Then, we can but accept the situation of the human race, as it is, since we have no historical data of its origin, that are beyond controversy and that would be accepted as evidence in a physiological point of view. But we need no ponderous evidence to show the truth of the premise, that animal life is not perpetuated except through sexual congress. Not life _only_, but good and evil of every degree; vice, folly, crime; love and hate; society, social evil and social good: all depend, largely, upon the sexual. It is the bond of our existence; it is the wheel of our fortune; it is our guiding star; and it may be our loadstone to crime and premature death. Passions leading to love, true and gentle, or jealousy, hate, revenge, murder and suicide, all hinge on circumstances connected, directly or indirectly, with the sexual. Our schools are conducted upon a foundation entirely sexual; educating each of the sexes in the role they are to pursue, with reference to exclusiveness in conduct. The girl is taught to pursue only such vocations, practices and manners as are becoming to her sex; the boy, on the other hand, is instructed not to enact girlish capers, but to pursue masculine vocations, from the childish toys to settled, adult labors. This all means nothing but distinctive development of the sexes.
