## Resource

This lecture discusses the ancient Greek philosopher Aristotle' work, On Interpretation, focusing on his discussion of what have come to be called "modalities" such as necessity, contingency, possibility, and impossibility, with the truth values of future seemingly contingent propositions in mind, for example that a sea-battle will or will not take place tomorrow. One possible approach is to say that since propositions must be either true or false, future propositions already are true or false of necessity and that we simply don't know their truth or falsity. Another is to say that it is necessary for them to be either true or false, but that neither of these truth values are necessary to contingent propositions referring to future events that have not yet happened.
