“The importance of falling in love lies not in how it feels, but in what it perceives. And as always with our feelings, the key moral issue is how truthful the perception is... Falling in love is a sign that this might be someone with whom you could make a good marriage. Still, it's not enough, because the feeling is not always as perceptive as it should be... So falling in love is not the basis for a good marriage. It's not even a requirement. Marriage does not depend on falling in love; it depends on the promises you make to each other in your wedding vows and then spend a lifetime keeping. As many people have pointed out, you can't promise how you'll feel. But you can promise to cultivate a virtue, such as the virtue of love.”
