"And you think this spirit prevails throughout Meccania?" I said. "I am perfectly sure of it," replied Slimey. "All our greatest artists offer their works freely to the members of the Second Class; all the most gifted scientists compete for places in the colleges for the training of the Military; the services of our best writers are at their disposal: we withhold nothing from them." "Then it is true, I gather, that the custom I have heard of, by which wives and daughters of other classes, if they are thought worthy by the Eugenics Board, are--shall I say--dedicated to the service of the Second Class, arouses no feeling of indignation?" "Indignation!" exclaimed the Professor of Theology. "It is a duty and a privilege." "But is it not contrary to the principles of the Christian religion? I confess I speak with some hesitation, as I do not belong to the Christian communion; but I have been told by some of the strictest of the Christian sects in other countries that such a practice is a violation of the Christian code." Professor Slimey refreshed himself, and I could see another long speech was coming. "That is a sample of the uncharitable criticism which is constantly being aimed at us, by those who cloak their envy and spite under the name of Christian doctrine. Yet they are utterly inconsistent with themselves. They admit the Doctrine of Development, yet they deny its application, except to suit their own purposes. Take Usury, for example. Christian doctrine, as expounded by the Fathers, regarded usury as sinful. Yet usury is practised in all so-called Christian countries without protest. Why? Because their system of Economics cannot work without it. I might give other illustrations, but that will suffice. Now Ethics must undergo development if there is to be progress in morals. The supreme well-being of the State gives the key to all progress in Ethics. If the custom you refer to were due to private concupiscence, we--and I speak for all Meccanian theologians--would be the first to denounce it. The sin of adultery is a spiritual sin, and exists only where carnal desire is the motive. Every theologian knows that the same physical act may be performed in conformity with the behests of the Mosaic law, or in direct disobedience of it. The one is a sacred duty, the other is sin. It is like the alleged obligation to speak the truth upon all occasions. There is no such obligation. We must look to the end in view. Where the supreme needs of the State demand concealment or even deception, the private ethical impulse to speak the truth to an enemy is superseded by the greater obligation to the State. The virtue of Chastity is not violated; it is raised, if I may say so, to its transcendent degree, by an act of sacrifice which implies the surrender of merely private virtue to the interests of the State; for you must remember that the State as developed by the Meccanian spirit is the highest embodiment of the will of God upon earth."
