Thanks also from another reader. I never thought of human attraction in this multi-layered way before. It’s amazing. If we could all see ourselves as multi-natured this way, we would gain so much richness and depth in our view of ourselves. One thing I wish you had talked about more, though, was the definition of romantic attraction. You never actually said what it was. I still don’t know what it is (it’s very hard to find a definition for this anywhere). I can understand the sensual, the sexual, the aesthetic, the emotional and the intellectual types of attraction, but if romantic attraction is something different from all these, what the heck is it? It seems to come closest to emotional attraction, yet people seem to feel that it’s its own thing. Very confusing.
