The explanation of why scientific methods work for us must be a causal explanation. It must show what facts about reality make the methods we employ to acquire knowledge suitable for doing so. The explanation has to show that the fact our methods work—for example, have reliable technological application among other things—is not a coincidence, still less a miracle or accident. That means there have to be some facts, events, processes that operate in reality, and which brought about our pragmatic success. The demand that success be explained is a consequence of science's epistemology. If the truth of such explanations consists in the fact these explanations work for us (as pragmatism requires), then it turns out that the explanation of why our scientific methods work is that they work. That is not a satisfying explanation.
