“These are the only paths of investigation to contemplate: how it both is and is not possible not to be…and how it is both unnecessary and necessary not to be”
αἵπερ ὁδοὶ μοῦναι διζήσιός εἰσι νοῆσαι·
ἡ μὲν ὅπως ἔστιν τε καὶ ὡς οὐκ ἔστι μὴ εἶναι, ….
ἡ δ’ ὡς οὐκ ἔστιν τε καὶ ὡς χρεών ἐστι μὴ εἶναι
Some great structure in this piece. The stripped down version on the twitter-feed (“the only paths of investigation: how it is and isn’t possible not to be; and how it is isn’t and is necessary not to be”) seems vaguely (and haphazardly) Heraclitean.
