  Whatever was Duhem’s initial motivation, his historical and philosophical work took on a life of its own. One cannot read Duhem’s numerous historical and philosophical tomes and think that his labor was only in the service of energetics and that the sole goal of his works was but a defense of its methods and its historical position. No doubt energetics might be a thread running through Duhem’s various works, and no doubt these works harmonize with the method of energetics as he conceives it, but energetics cannot be the whole story.
