The only form of the orthodox imputation which is even decently plausible is the suggestion that the loss of religious belief may leave some men more ready than before to venture on vice that is not legally punishable. This is no doubt theoretically possible; and in cases where boys have had such a religiously bad education that they know of no rational veto on misconduct, harm may sometimes arise on their finding that the religion taught them is incredible. But young men who reason so far are likely to reason further; and in any case a few plain considerations will serve to convince any candid mind that there is no causal connection between scepticism and vice; though it stands to reason that the habit of scepticism will promote the critical discussion on the institution of marriage. On the one hand, the sexual instinct has in all ages gone to the worst excess under the auspices of religions which expressly glorified asceticism; and the facts of the life of the ages of faith in Europe make it clear that, even on the orthodox definition of vice, there cannot possibly be more of it in the future than there has been in the past. On the other hand, the utilitarian arguments against vice, properly so called, are much better fitted to impress than the religious; and they leave no such loophole as the others inevitably do in respect of the Christian doctrine of pardon for sin, to say nothing of the iniquity of the Christian ethic which holds one and the same act ruinous in a woman and venial in a man. Of course, if the celibate life, and marriage without possibility of divorce, be made the standard of virtue, rationalism is likely to give piety plenty of occasion for outcry in matters of morals, as in matters of opinion.
