As in all natural humor, though, the amusement to be derived from this sort of situation, where the individual comes in contact with the universal, is limited. For example, there's a party. Everyone is waiting expectantly for the great writer to put in an appearance. Instead of producing illuminating conversation, the first thing he does is ask where the bathroom is. At the other extreme, the passion for mathematics, though it can be in selected persons quite as intense as any love affair, is too spiritual.
Sexual love has both nature and spirit and the desire for personal choice.
The desire begins with the individual object but ends in bed where things are generalized. I think that there's a good American story to illustrate this point. A man is on a visit to Chicago. He enters a restaurant. Yes, he sees a very beautiful girl in the restaurant, exquisitely beautiful, ravishingly beautiful.
