According to Seungbae Park, two versions of the pessimistic induction argument against scientific realism, what he calls the "absolute" and "relative" versions, each fail for the same reason. Depending on whether their respective premises refer to distant or recent past theories, either each premise is implausible, or the conclusion does not probably follow from them. I suggest that Park has misconstrued the sort of argument his pessimist interlocutors rely on. When properly recast, the absolute and relative versions of the argument (...) become deductive rather than inductive. The result in each case is an argument that, contra Park, has both a plausible premise and a conclusion that follows from it. (shrink)
