 This scenario illustrates that there are different explanations, corresponding to different senses of causation, each answering a different kind of question. When the different senses of causation are disambiguated, then it becomes clear that there is no conflict between the explanation of the theoretical physicist and that of the car mechanic, because they answer different kinds of questions, questions which differ because they are entailed by different absolute presuppositions. Explanations genuinely conflict with one another only if they provide answers to the same question, but they do not if they are answering different questions. The task of presuppositional analysis is to undo the conceptual knots in which our thoughts get tangled when we mix and match answers of one kind with questions of another by failing to see the entailment relations which hold between presuppositions, the question to which they give rise, and the sort of propositional answers which address those questions:
