We tend to think in terms of fixing blame, of establishing adultery and making clear who did what to whom, when what is most important is not what was done but that no one be hurt. It's not that we care that much if our mate rubs off a few cells of epidermis in friction with someone else, it's that we are all afraid if he does, he'll stop loving us. And men who've always had affairs, considering it good for their morale, find that they are fearful just like their wives when the shoe is on the other foot. Any new ethic, if it's to work, will have to find ways of reconciling growth with commitment, change with loyalty, and freedom with alienation, because a world in which new loyalties constantly replace old ones will make neurotics of us all.
