Abstract
In this paper I deal with Alexander of Aphrodisias’ theory of categorical μὴ κατὰ χρόνον propositions, namely of propositions which are neither necessity nor contingency propositions, but which are true not only at a certain instant in time. I argue that these propositions are true at least at two instants in time, but their presentation does not commit Alexander to a revision of his general semantic scheme for modal propositions, in which he showed that categorical propositions are not necessity propositions, and thus cannot be true at every instant in time. In the last section, I shall argue that Alexander’s presentation of categorical μὴ κατὰ χρόνον propositions is linked to his theory of predication and that such a semantic framework may explain the apparently difficult classification of this set of propositions.
