There is no justification for love, for if there were, then it would not be love. If we love because we are compelled through force, then it is not love. If I give some money to the poor only because someone is holding a gun to my head and demanding the action, then this is not a loving action. Neither is it loving if I act in order to gain a reward, even if the reward is simply the feeling that comes from doing the act. As soon as we say that we should love, then love disappears, for love is the law that has no law, the way that knows no 'should'. Love is the law that tells us when to subvert the law, when to obey the law and when to break with laws, yet love is a lawless law that cannot be argued for.
