“Upon the proper use and conservation of sexual force the progress of civilization itself depends. All history shows that just in proportion as the sex instinct is kept sacred, pure, and the life essence properly used and converted into creative, productive power, does a nation reach a high state of civilization. Wherever this instinct becomes generally perverted, as it did in ancient Rome, people become devitalized, lose their physical and mental stamina, and rapidly deteriorate. Where it is protected by virtue and purity of life, the nation rises in the scale of civilization; where it is abused, perverted, the nation sinks to the level of low-flying ideals.”
