Awe is felt when your perception is overwhelmed by what you're experiencing and you can't wrap your brain around it. Most people have felt awe, but not enough of it. My cellphone is awesome. I don't know in great detail how it works, and I don't use all the features in it. I remember rotary phones. People are awesome. Most of us don't know ourselves, much less other people. The world is beyond our comprehension. It's amazing that we are able to operate within it. We tend to take it for granted.
Descartes reasoned that he couldn't know anything except that we could doubt his own existence. He thought he could know things by God but he might not have been able to prove it. Somehow we are able to function within this great mystery.
We can have relationships with other people. Some people are overwhelmed and try to control others. Realizing how little control we have can help this problem.
Some scientists did an experiment with baby ducks. The duck was in a nest while the scientists moved a figure shaped like a Christian cross across the "sky." When it moved upward, with the crossbar like the wings of a hawk in front, the duck hunkered down. When the cross moved the other way, like it had wings in the back like a goose, the duck sat up. Whether we view the world as good or threatening can be very simple.
Loving unconditionally means accepting other people and being in awe of them. Marx's theory, "From each according to his ability, to each according to his need," doesn't work in economics, but it works with compassion. A Marxist approach to sex is to give your body freely to others instead of putting a market price on it. Again, not so much about sex, but compassion. If your emphasis is love instead of reason, the prisoner's dilemma is less of a problem.
We have to trust that we can act in the world. Trust involves giving up control. I think this is where desire comes in. We want things but can't acquire them. Our instinct is to control. This is understandable. The wiser move is to let go. Usually you can't get it right now, but it might develop later. It's a continual turning towards (German abbiegen) the moment.
