 In fact, however, Rowe’s argument is unsound. The reason is connected with the point that while inductive arguments can fail, just as deductive arguments can, either because their logic is faulty, or their premises false, inductive arguments can also fail in a way that deductive arguments cannot, in that they may violate a principle—namely, the Total Evidence Requirement—which I shall be setting out below, and Rowe’s argument is defective in precisely that way.
