The Flux of All Things and Constant Alteration of the Self

Notes

1. §9.19.1ἐν μεταβολῇ — Throughout this section, the copula verbs expressing existence or state are omitted. We supply ἐστί (or εἰσί) for πάντα (neuter plural) in the first clause, εἶ for αὐτὸς σὺ (second person singular) in the second, and ἐστί for ὁ κόσμος ὅλος (third person singular) in the third.
2. §9.19.1κατά τι — An adverbial phrase consisting of the preposition κατά and the neuter accusative singular pronoun τι, meaning 'in some respect' or 'in a way'. It modifies φθορᾷ (decay/destruction) to qualify the decay of the self as a partial decomposition rather than absolute annihilation.
3. §9.19.1καὶ ὁ κόσμος δὲ ὅλος — The combination καὶ ... δέ is a conjunctive expression meaning 'and also' or 'and ... too'. It introduces ὁ κόσμος ὅλος (the whole universe) as the subject to indicate that the preceding description of being in change, alteration, and decay applies equally to the macrocosmic universe.
