THE VALUE OF THE BELIEF IN SUPERHUMAN PASSIONS.—The institution of marriage stubbornly upholds the belief that love, although a passion, is nevertheless capable of duration as such, yea, that lasting, lifelong love may be taken as a general rule. By means of the tenacity of a noble belief, in spite of such frequent and almost customary refutations—thereby becoming a _pia fraus_—marriage has elevated love to a higher rank. Every institution which has conceded to a passion the _belief in the duration of the latter_, and responsibility for this duration, in spite of the nature of the passion itself, has raised the passion to a higher level: and he who is thenceforth seized with such a passion does not, as formerly, think himself lowered in the estimation of others or brought into danger on that account, but on the contrary believes himself to be raised, both in the opinion of himself and of his equals. Let us recall institutions and customs which, out of the fiery devotion of a moment, have created eternal fidelity; out of the pleasure of anger, eternal vengeance; out of despair, eternal mourning; out of a single hasty word, eternal obligation. A great deal of hypocrisy and falsehood came into the world as the result of such transformations; but each time, too, at the cost of such disadvantages, a new and _superhuman_ conception which elevates mankind.
