What do I know? I know that human beings and fundamental particles share one absolute commonality: they exist in their interactions. In between times, their positions and trajectories are indecipherable even to themselves. I know that in planets, such interactions are called conjunctions, and that Isaac Newton came upon the notion of gravity by the alchemy that is called the attraction of souls. I know that Albert Einstein proposed two persons hanging in space alone in a universe that contained nothing else, and observed that if one of them is spinning, there is no way to determine which. Everything depends upon its relationship to everything else for its meaning.
