§8.11.1Τοῦτο τί ἐστιν αὐτὸ καθ’ αὑτὸ τῇ ἰδίᾳ κατασκευῇ, τί μὲν τὸ οὐσιῶδες αὐτοῦ καὶ ὑλικόν, τί δὲ τὸ αἰτιῶδες, τί δὲ ποιεῖ ἐν τῷ κόσμῳ, πόσον δὲ χρόνον ὑφίσταται;
What is this, itself by itself in its own constitution: what is its substantial and material part, and what is its causal part? What does it do in the world, and for how long a time does it subsist?
