Really. Love is a choice, and as such it is ultimately rooted in exactly the domain that people, for whatever reasons, always want to dissociate it from: Reason. Logic. Rationality. Think about it: Our most sacred, most traditional wedding vows involve promising to love another person for the rest of your life. How can a promise be made about how one will feel (ie. emotion) in a far distant future? The answer is: It cannot. Emotion is too variable, too unpredictable. If love were an emotion, no wedding vow that includes a clause on eternal love can ever be valid or true. All these weddings are then a farce. The good news is, they're not, because love is not an emotion.
