Chapter 55
The category of time shows time. Thus, when we are asked when this happened, we reply that it happened last year, or the year before last, both of which indicate time. There are as many species of the category of time as there are differences of time. These last are three: present, past, and future.
[42] {Περὶ τῆς ποτέ.} Τὸ ποτὲ χρόνον δηλοῖ: ἐρωτώμενοι γὰρ ‘πότε ἐγένετο τόδε;’ λέγομεν ‘πέρυσι, προπέρυσι’, ἅτινα χρόνον σημαίνουσιν. Εἴδη δὲ τῆς ποτὲ κατηγορίας εἰσὶ τοσαῦτα, ὅσαι αἱ τοῦ χρόνου διαφοραί. Τρεῖς δέ εἰσιν αὗται: ἐνεστώς, παρῳχημένος, μέλλων.
