“From the Future of Marriage. Those noble, free-minded women who set themselves the task of educating and elevating the female sex should not overlook one factor: marriage conceived of in its higher interpretation, the spiritual friendship of two people of the opposite sexes, that is, as marriage hoped for in the future, entered into for the purpose of begetting and raising a new generation. Such a marriage, which uses sensuality as if it were only a rare occasional means for a higher end, probably requires and must be provided with a natural aid: concubinage.”
Friedrich Nietzsche, “Human, All Too Human”, 1878.
