The Will to Power · Friedrich Wilhelm Nietzsche
732.
In bourgeois marriages, naturally in the best sense of the word marriage, there is no question whatsoever of love any more than there is of money. For on love no institution can be founded. The whole matter consists in society giving leave to two persons to satisfy their sexual desires under conditions obviously designed to safeguard social order. Of course there must be a certain attraction between the parties and a vast amount of good nature, patience, compatibility, and charity in any such contract. But the word love should not be misused as regards such a union. For two lovers, in the real and strong meaning of the word, the satisfaction of sexual desire is unessential; it is a mere symbol. For the one side, as I have already said, it is a symbol of unqualified submission: for the other, a sign of condescension--a sign of the appropriation of property. Marriage, as understood by the real old nobility, meant the breeding forth of the race (but are there any nobles nowadays? _Quaeritur_),--that is to say, the maintenance of a fixed definite type of ruler, for which object husband and wife were sacrificed. Naturally the first consideration here had nothing to do with love; on the contrary! It did not even presuppose that mutual sympathy which is the _sine qua non_ of the bourgeois marriage. The prime consideration was the interest of the race, and in the second place came the interest of a particular class. But in the face of the coldness and rigour and calculating lucidity of such a noble concept of marriage as prevailed among every healthy aristocracy, like that of ancient Athens, and even of Europe during the eighteenth century, we warm-blooded animals, with our miserably oversensitive hearts, we "moderns," cannot restrain a slight shudder. That is why love as a passion, in the big meaning of this word, was invented for, and in, an aristocratic community--where convention and abstinence are most severe.
