*Abstract:*

The ingenious logic of Chrysippus of Soli (c. 279 - c. 206 BC), the third
head of the Stoic school, encompasses modality, deixis, conditionals and
many more phenomena studied in contemporary formal semantics. This talk
explores Chrysippus' response to the Master Argument of Diodorus Cronus, an
ancient challenge to unrealized possibilities. In his response, Chrysippus
argued that some true conditionals have possible antecedents and impossible
consequents, such as "If Dio has died, this one (pointing at Dio) has died".
I argue that a proper understanding of this response requires the Kaplanian
distinction between character and content, a distinction which is largely
absent from modern scholarship on Stoic logic. I develop a model theory for
an appropriate fragment of Stoic logic within contemporary branching-time
and two-dimensional semantics. The talk adds to the inventory of striking
parallels between Stoic logic and modern philosophy of language and bears
witness to the sophistication of Stoic logic and its relevance to
contemporary thought. [This talk previews aspects of a course I will teach
at ESSLLI 2025 in Bochum. No previous knowledge in ancient logic is
presupposed.]

We hope many of you will find the time to attend.
