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 opposite sexes, that is, marriage as hoped for by 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. For if, for reasons of the man's health, his wife is also to serve for the sole satisfaction of his sexual need, a false point of view, counter to the goals we have indicated, will be decisive in choosing a wife. Posterity becomes a coincidental objective; its successful education, highly improbable. A good wife, who should be friend, helpmate, child-bearer, mother, head of the family, manager, indeed, who perhaps has to run her own business or office separate from her husband, cannot be a concubine at the same time: it would usually be asking too much of her. Thus, the opposite of what happened in Pericles' times in Athens could occur in the future: men, whose wives were not much more than concubines then, turned to Aspasias as well, because they desired the delights of a mentally and emotionally liberating sociability, which only the grace and spiritual flexibility of women can provide. All human institutions, like marriage, permit only a moderate degree of practical idealization, failing which, crude measures immediately become necessary.
