There was hugely more sense in the old people who said that a wife and husband ought to have the same religion than there is in all the contemporary gushing about sister souls and kindred spirits and auras of identical colour. As a matter of fact, the more the sexes are in violent contrast the less likely they are to be in violent collision. The more incompatible their tempers are the better. Obviously a wife’s soul cannot possibly be a sister soul. It is very seldom so much as a first cousin. There are very few marriages of identical taste and temperament; they are generally unhappy. But to have the same fundamental theory, to think the same thing a virtue, whether you practise or neglect it, to think the same thing a sin, whether you punish or pardon or laugh at it, in the last extremity to call the same thing duty and the same thing disgrace — this really is necessary to a tolerably happy marriage; and it is much better represented by a common religion than it is by affinities and auras.
