² There are apparent verbal echoes of the Timaeus at von Arnim, H., Stoicorum veterum fragmenta (Leipzig, 3 vols., 1903–5Google Scholar; henceforth SVF), 1.88 (matter is like wax) and 2.318 (matter is the ‘receiver of all’, cf.

³ For what it is worth, later Platonic commentators imply that Zeno did in fact derive his theory of matter from the Timaeus: cf. Calcidius in Tim. 292 (SVF 1.88).

⁷ … δύο τὰς ἀρχὰς βούλεται ποιεῖν τὸ μὲν ὑποκείμενον ὡς ὕλην ὃ προσαγορεύει ‘πανδεχές’, τὸ δὲ ὡς αἴτιον καὶ κινοῦν ὃ περιάπτει τῇ τοῦ θεοῦ καὶ τῇ τοῦ ἀγαθοῦ δυνάμει (text and translation: fr. 230 Fortenbaugh et al.).

⁸ This line of speculation has been pressed especially by Sedley (n. 1).

⁹ Of course, this view itself may owe something to Zeno's reflection on Plato; for an influential account of Zeno's debt to the ontology of the Sophist in particular, see Brunchwig, J., ‘The Stoic theory of the supreme genus and Stoic ontology’, in id., Papers in Hellenistic Philosophy (Cambridge, 1994), 92–157CrossRefGoogle Scholar, esp. 118–23.

¹¹ This is clearly implied at 29a6–b1, and stated explicitly at 46e.

¹² The goodness of the Demiurge is first mentioned at 29a and is elaborated upon at 30a.

¹³ Cf. Procl. In Ti. 1.299–319. A further likely motivation for this identification is the Aristotelian claim (argued in Metaphysics Λ) that the only activity appropriate for a god is the best activity, i.e. theoretical contemplation, together with the Platonic assumption that the Forms are the proper objects of theoretical contemplation. Cf. O'Meara, D., Plotinus: An Introduction to the Enneads (Oxford, 1995), 70–5.CrossRefGoogle Scholar

¹⁴ See e.g. Plotinus, Enn. 3.2.2, 5.8.7 and 6.7.1–15 (on which, see Thaler, N., ‘Traces of good in Plotinus's philosophy of nature’, JHPh 49 [2011], 161–80Google Scholar, at 162–7).

¹⁵ This is not to deny that the Demiurge, in thinking about (say) the Forms that correspond to natural kinds, is in some sense thinking about what a well-ordered cosmos would be like. The important point for my purposes is that on the Neoplatonist account he is not – and indeed cannot be – thinking about the well-ordered sensible object that is our cosmos, or about its sensible components; for this would be a failure of his goodness.

¹⁹ Menn, S., Plato on God as Nous (Carbondale, 1995)Google Scholar, 14 comments that διάνοια and λογισμός denote ‘primarily the act of reasoning from premises to conclusions’, but he intends thereby to distinguish the sense of these terms from that of νοεῖν (the intuitive grasp of an intelligible object) and of νοῦς (the virtue associated with reason). According to Menn (7–10), the craftsman of the Timaeus is to be identified wholly and exclusively with νοῦς; and he takes νοῦς to be the Form of the virtue of good reasoning (19–24). He does not discuss how (or whether) the dialogue's numerous attributions of διάνοια and λογισμός to the Demiurge fit with this view. Johansen (n. 10), 84–6 offers what he calls a ‘non-psychological reading of these terms’, seeing them as dramatic descriptions of craft itself, that is, as expressing in explicit form the means–end structure implicit in every craft. I agree that such a reading is possible; my point is that it is possible only despite the usual connotations of such language.

²³ ἡγήσατο γὰρ αὐτὸ ὁ συνθεὶς αὔταρκες ὂν ἄμεινον ἔσεσθαι μᾶλλον ἢ προσδεὲς ἄλλων.

²⁴ αὐτάρκης δ' εἶναι λέγεται μόνος ὁ κόσμος, διὰ τὸ μόνος ἐν αὑτῷ πάντα ἔχειν ὧν δεῖται· καὶ τρέϕεται ἐξ αὑτοῦ καὶ αὔξεται, τῶν ἄλλων μορίων εἰς ἄλληλα καταλλαττομένων. Plutarch contrasts this passage with another from the same book at 1052c (SVF 2.604) about the gradual growth of the soul of the cosmos, which suggests that it was part of a discussion about the life cycle of the cosmos (another extant fragment of On Providence, Book 1 describes the state of the world during the conflagration in terms of being all soul and no body: SVF 2.605). In any case, Plutarch manages to find, among other putative contradictions, a contradiction in the notion that the cosmos ‘grows’ through being nourished by itself. He then attempts to turn the Timaeus against Chrysippus by asserting, in a close paraphrase of 33c7–8, that the cosmos cannot grow, since has its own waste (ϕθίσις) for nourishment; however, this is probably exactly what Chrysippus has in mind in speaking of cosmic nourishment through ‘rearrangement’. Interestingly for our purposes, Plutarch's point, however frivolous it may be, confirms that he too takes Chrysippus to be drawing upon Timaeus 33c for his argument. Cf.
