No one will ever be able to say where love penetrates when it lifts the bottom of human nature, where pearls and corals are intermixed with mud. It is a diver that brings to light strange and unknown things and reveals to the astonished eye of the observer new things never before conceived; it is the most daring and the most fortunate of excavators. How many simple natures of young girls, how many vulgar talents of men are perturbed, agitated and renovated by the contact of the new god, who seems to evoke from the abysses all silent passions, all dormant ideas, all the phantoms of heart and thought! The deep simmering of psychical elements at the contact with love almost always announces the birth of a second moral nature and, revivifying life, marks a new era in it. Of our birth we are always ignorant, and of our death almost always unconscious; between the "to be" and the "not to be" only one third and great thing is possible--"to love." While the common people judge from the hair on the face and from the deepened voice that a boy has become a man, a tremendous profound earthquake warns him that he must love, that he already loves; and while mothers behold with affectionate trepidation the rounding of their daughters' form to womanhood, another profound earthquake warns the girl that she must love, that she already loves. In the loving season many animals change color and shape, adorn themselves with new feathers, or arm themselves with new weapons; with the nuptial robe they assume different habits and singular abilities; mutes, they become clever singers; obtuse, they are transformed into skilled architects; granivorous, they become carnivorous; if the earth is their habitat, they become winged messengers of the skies; if caterpillars, they are metamorphosed into butterflies. So it is with man, although such transmutation hardly affects his epidermis, but sinks into the veins and the meanders of his physical nature. The phase of puberty deserves to be dealt with separately; it will suffice here to remark that every force redoubles, every vigor refines, and while, with our growing to manhood, forces and energies prepare and grow, love calls forces and energies into action. Puberty declares us in a state of war; love calls us to the battle. Defenseless if we have not reached puberty, we are armed if we have reached it; armed and combative if we have reached it and are in love.
