A good life cannot be founded upon fear, prohibition, and mutual interference with freedom. Where faithfulness is achieved without these, it is good, but where all this is necessary it may well be that too high a price has been paid, and that a little mutual toleration of occasional lapses would be better. There can be no doubt that mutual jealousy, even where there is physical faithfulness, often causes more unhappiness in a marriage than would be caused if there were more confidence in the ultimate strength of a deep and permanent affection.
