This situation has its counterpart in feeling. Replenishment is a sort of delayed breathing, as if the animal had to hunt for air: it necessitates more activity than it contains; it engages external senses in its service and promotes intelligence. After securing a dumb satisfaction, or even in preparing it, it leaves the habits it employed free for observation and ideal exercise. Reproduction, on the contrary, depletes; it is an expense of spirit, a drag on physical and mental life; it entangles rather than liberates; it fuses the soul again into the impersonal, blind flux. Yet, since it constitutes the primary and central triumph of life, it is in itself more ideal and generous than nutrition; it fascinates the will in an absolute fashion, and the pleasures it brings are largely spiritual. For though the instrumentalities of reproduction may seem gross and trivial from a conventional point of view, its essence is really ideal, the perfect type, indeed, of ideality, since form and an identical life are therein sustained successfully by a more rhythmical flux of matter. It may seem fanciful, even if not unmeaning, to say that a man’s soul more truly survives in his son’s youth than in his own decrepitude; but this principle grows more obvious as we descend to simpler beings, in which individual life is less elaborated and has not intrenched itself in so many adventitious and somewhat permanent organs. In vegetables soul and seed go forth together and leave nothing but a husk behind. In the human individual love may seem a mere incident of youth and a sentimental madness; but that episode, if we consider the race, is indispensable to the whole drama; and if we look to the order in which ideal interests have grown up and to their superposition in moral experience, love will seem the truly primitive and initiatory passion. Consciousness, amused ordinarily by the most superficial processes, itself bears witness to the underlying claims of reproduction and is drawn by it for a moment into life’s central vortex; and love, while it betrays its deep roots by the imperative force it exerts and the silence it imposes on all current passions, betrays also its ideal mission by casting an altogether novel and poetic spell over the mind.
