Nature admits of no permanence in the relation between man and woman. It is only man's egoism that wants to keep woman like some buried treasure. All endeavors to introduce permanence in love, the most changeable thing in this changeable human existence, have gone shipwreck in spite of religious ceremonies, vows, and legalities.
Man is the one who desires, woman the one who is desired. This is woman's entire but decisive advantage. Through man's passions, nature has given man into woman's hands, and the woman who does not know how to make him her subject, her slave, her toy, and how to betray him with a smile in the end is not wise.
