hysics should make us wary of all such arguments. Historically sensitive and cautious though he was, Duhem blundered. Why should we think we can do better? The history of physics is a Delphic oracle and its future, shaped as it will be by our contingent and accidental approach to the world, is unlikely to be predictable with any confidence.
