Do you still laugh sometimes? Do you know how to lose yourself completely all over again in a moment of elemental joy—because of a view of houses, a human atmosphere, a song, a bit of landscape, a piece of film: in short a piece of good warm life? It’s something I love so much in you.
[Simone Weil, from a letter to Albertine Thévenon]

Because in order for love to be present there must be a lover, a beloved, and the love between them. So, he says, you can’t have love without also having three-in-one.
