I think happiness is like mathematics. Everything is in equilibrium, not too much of one thing or too little of the other. Taken at a distance, the entire universe is happy, because it is in equilibrium. We think. Actually, we don't know. We like to imagine that there is a sense of everything somewhere, and we could find it, if we only knew where to look.
Maybe it's not that way at all. Maybe the entire universe is in conflict, factions of atoms and molecules hell-bent on the total annihilation of other atoms and molecules. Maybe we, as in everything there is, have been at war since time began. Maybe conflict and war fuel the entire universe Bah humbug. Think I'll go make some popcorn.
