I don't feel very loving right now, but I don't have to feel any way to talk about love, because love is not merely a feeling. A lot of people think that love is just the special way of feeling about a person, or the warm fuzzy that comes from being with a certain person. Love is much more than just a special way of feeling. It is also a value, a commitment, a sense of orientation toward others, a philosophy, a way of being in the world (an existential engagement).
There are degrees of love and kinds of love. The Greeks called sexual and romantic love Eros From which we get our word "erotic." The kind of love friends feel they called Phileo or "brotherly love" (as in "Philadelphia"). The highest form of love they called Agape. That is usually the kind of love the Bible speaks of when it speaks of God's love for us. 1 John tells us "He who loves knows God for God is love."
Agape Means: the will to value the other, or the will to the good of the other; the desire for the other to have the best. It entails the idea of according the other all rights and human dignity. It is not personal, it's a commitment to all people. Agape is sometimes translated Charity (as in kJ trains 1 Corinthians 13 "if I speak with the tongue of men and of angles and have not charity") but this is more condescending and patronizing than the actual meaning of the term. Charity can be paternalistic in the negative sense, controlling, colonizing, derogatory. Agape is a totally positive thing; one must actually seek the good of the other whatever that may be, even against one's own interest.
Now I will start saying "crazy stuff," these are things that I have theorized about and I guess they make up the radical edge of my own philosophy because they have been scoffed at plenty of times on these boards. But I don't care I'm saying it anyway.
Basis of everything: connection with Being
When I say love is the basis of everything, I mean it really is. I believe that when the Bible says "God is love" it means it literally. In other words, we should put an "itself" there. God is "love itself,": the thing that love is actually the essence of what God is. Now you may ask how can God be both being itself and love itself? Because these two are inextricably bound up together.
Love is giving, the idea of seeking the good of the other, according the other full human dignity equal to one's own, these are ideas that entail give over, supplying the other with something. It's a positivity in the sense that it supplies an actual thing to someone. Being also shares these qualifies. Being is giving in the sense that it bettors itself upon the beings and they have their existence. It is positive in the sense that it is something and not taking something away, it's not a void as nothingness is, but moves in the direction of filling a void; nothingness becomes being, the existence of things.
So love and being are really the same impulse and they both unite in the spirit of God. God is the basis of all being, of all reality. God's character is love; that is God seeks the good of the other and bestows upon us the ultimate human dignity of being a child of God.
Motivating force behind creation
Love is the basic motivating force behind creation. God's motive urge to create was not out of a need due to looniness, but out of a desire to create as an artist, and desire is fueled by love. Art is love, artists love art, as revolutionaries love. Revolutionaries are in love and their revolutions are often expressions of love, what He Guava called "a strange kind of love, not to see more shiny factories but for people." So God creates as a need to bestow love, which entails the bestowing of being.
Now let's not have a bunch of lectures about "perfection" based upon not knowing what perfection is. Let's not have a buck of Aristotle thrown in as though it were the Bible. There is no base line for comparison from which one can really make the judgment that need is imperfection; especially the sort of need one feels to be creative or to bestow love; that is a different sort of need than the need for food or shelter.
Basis of morality
Love is the basis of morality. Love is the background of the moral universe, as Joseph Fletcher said. Austin said it too. That means all moral decisions are made with ultimate reference to God's love which is the driving force behind morality. Many people think Christian morality is about stopping impurity. These people regard sex as the greatest offense and think that basically sin = sex. But nothing is further from the truth. Sin is not sex, sin is an unloosing nature, or a selfish desire to act in an unloosing manner.
Love requires selfless giving over OT the other for the good of the other. That means all moral actions must ultimately evaluated with reference to their motivational properties. That's why Jesus spoke as he did in the sermon on the mount: if you hate you are a murderer. Because the motivation itself is the true essence of the sin, the rejecting of love and acceptance of self as the orbit creates the motive that eventually leads to the act. He is not saying that the act sin OT sinful of course, but that the sin begins with the motive not just with the act. In that sense morality is somewhat teleological, although I normally eschew teleological ethics. I am not saying that the morality of a given act is based upon outcome, but that the end toward which moral motions are given is the goal of doing love.
