Skimming old modal logic textbook. They casually show Diodorus’ master argument for fatalism is valid then move on. I mean, ok, maybe I’d like to pause on this? In any case #stoicism confirmed I guess. (Yeah yeah I know the difference between validity and soundness don’t @ me.)

Thanks! The first premiss is the controversial one, right? (Looks false to me.)
Aye, Diodorus apparently had a well developed theory of modality to back it up (and the argument is valid under that interpretation of the modal operators) - but just scanning them without having thought about it too much it'd be the first I'd disagree with too.
