sexual love is a relationship between two people, in which a third party can only be superfluous or troublesome, whereas civilization rests on relations between quite large numbers of people. When a love relationship is at its height, the lovers no longer have any interest in the world around them; they are self-sufficient as a pair, and in order to be happy they do not even need the child they have in common. In no other case does Eros so clearly reveal what is at the core of his being, the aim of making one out of more than one; however, having achieved this proverbial goal by making two people fall in love, he refuses to go further.
