In sexual desire, love, the expectation of unbounded happiness is the primary element. The feeling of dependence is of secondary development. The nucleus of this feeling exists in both parties, but it may remain undeveloped in one. As a rule, owing to her passive part in procreation and social conditions, it is more pronounced in woman; but exceptionally this is true of men having minds that approach the feminine type. In both the religious and sexual spheres love is mystical, transcendental. In sexual love the real purpose of the instinct, the propagation of the species, does not enter into consciousness; and the strength of the desire is greater than any that consciousness of purpose could create. In religion, however, the good sought and the object of devotion are of such nature that they cannot become a part of empirical knowledge. Therefore, both mental processes give unlimited range to the imagination. But both have an immortal object, in as far as the bliss which the sexual sentiment creates in fancy seems incomparable and infinite in contrast with all other pleasurable feelings; and the same is true of the promised blessings of faith, which are conceived to be eternal and supreme. From the correspondence between the two states of consciousness, with reference to the commanding importance of their objects, it follows that they both often attain an intensity that is irresistible, and which overcomes all opposing motives. Owing to their similarity in that their objects cannot be attained, it follows that both easily degenerate into silly enthusiasm, in which the intensity of feeling far surpasses the clearness and constancy of the ideas. In both cases, in this enthusiasm, with the expectation of a happiness that cannot be attained, the necessity of unconditional submission plays a part. Owing to the correspondence in many points between these two emotional states, it is clear that when they are very intense the one may take the place of the other; or one may appear by the side of the other, since every intensification of one element of mental life also intensifies its associations. The constant emotion thus calls into consciousness now one and now the other of the two series of ideas with which it is connected. Either of these mental states may become transformed into the impulse to cruelty (actively exercised or passively suffered).
