The Importance of Error Analysis in the Process of Science

There are no scientific studies that show animals experience pain, much less that they suffer. All that we have are proxies and they might not even be proxies for pain. Saying that particular enzyme levels are an indication of pain is untrue or not possible to conclude until such time as we have a scientific theory of what pain is. So I'm just going to steal David's thunder a little bit here for what is to come. What he's talking about now is the importance of, indeed, the centrality of errors in the process of science. In physics we have the special capability of being able to quantify our degree of uncertainty,. Now, this is not uncertainty in sort of the epistemological sense
