“There can be no sexual love without lust; but, on the other hand, until the currents of lust in the organism have been irradiatedas to affect other parts of the psychic organism--at the least the affections and the social feelings--it is not yet sexual love. Lust, the specific sexual impulse, is indeed the primary and essential element in this synthesis, for it alone is adequate to the end of reproduction, not only in animals but in men. But it is not until lust is expanded and irradiated that it develops into the exquisite and enthralling flower of love.”
