The account of induction, in particular, is much less probabilistic than that in the Rhetoric; it never really becomes clear whether these arguments are supposed to be deductive or not. Sometimes such inductions appear to be inconclusive, and it is said that if someone refuses to admit the conclusion, one is justified in asking what objection he has.48 On the other hand the Prior Analytics suggests that induction must be complete, that is, all the instances must be surveyed.
