We believe in causation

We believe in causation -- that is, that everything that happens has a cause, or to put it the negative way, nothing that happens can happen without a cause. People this is just a belief. In our world it seems to be the case, but we can't prove it. All sorts of things happen that are mysteries to us. We assume they had a cause but maybe they didn't.

We do know, at least the scientists know and we are wise to accept their long-held consensus, that at the atomic and sub-atomic level this is not quite the case. Given a single uranium atom, we know that at some point it will decay, but without cause. It will just happen. We can't say it is random either because if we have a large collection of uranium atoms, we can predict very exactly how many will decay each second -- just not which ones.
