This article deals with Ockham’s analysis of the problem, explained by Aristotle in the ninth chapter of De Interpretatione, of determining the truth of contingent propositions about the future, as well as its relationship to what Ockham himself proposes, ‘in accordance with truth and faith’, on the subject. In this respect, three theses are generally proposed on the basis of Ockham’s reading of Aristotle: that Ockham regarded the Aristotelian solution as an error, and thus disagreed with it; that Ockham clearly saw the Aristotelian solution as pointing towards a three-valued logic; and, finally, that Ockham denied the doctrine of the “necessity of the consequent”. Notwithstanding, it will be argued here that only the last of these is correct.
