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.

But it is not until lust is expanded and irradiated that it develops into the exquisite and enthralling flower of love.

Those persons who are burning to display heroism may rest assured that the course of social evolution will offer them every opportunity.
