As a philosopher of science, what is proof? What constitutes proof?
A. Well, there are all kinds of different kinds of proof. There’s deductive proof, but that’s really not relevant to empirical science. In science we have inference to the best explanation. We construct theories, we take all of the evidence at our disposal and we weigh, we judge, we make a determination as to what makes sense to us. Human beings weigh these decisions in different ways, therefore they come to different overall opinions about what makes sense.
