 Łukasiewicz’s interpretation of the Aristotelian text was disputed by Prior (1962, p.240 ff.), who pointed out that there is a significant difference between Łukasiewicz’s trivalent logic and Aristotle’s text. Prior pointed out that according to Aristotle it is true already today, that either there will \(or\) there will not be a sea-battle tomorrow, whereas this disjunction, as just mentioned, is undetermined according to Łukasiewicz’s trivalent logic.
