Possibilities don't add up, they multiply.

Once we admit that there is room for newness - that there are vastly more conceivable possibilities than realized outcomes - we must confront the fact that there is no special logic behind the world we inhabit, no particular justification for why things are the way they are. Any number of arbitrarily small perturbations along the way could have made the world as we know it turn out very differently.
