 Some authors have argued that in fact S does not rely on any premise or even presupposition that would require us to already know the conclusion of X. S is then not a “premise circular” argument. Rather, they claim, it is “rule-circular”—it relies on a rule of inference in order to reach the conclusion that that very rule is reliable. Suppose we adopt the rule R which says that when it is observed that most Fs are Gs, we should infer that most Fs are Gs. Then inference X relies on rule R. We want to show that rule R is reliable. We could appeal to the fact that R worked in the past, and so, by an inductive argument, it will also work in the future. Call this argument S*:
