Plato, Euthydemos 294b

“Are you also talented at these kinds of things, counting the stars and the sands?”

Ἦ καὶ τὰ τοιαῦτα, τοὺς ἀστέρας, ὁπόσοι εἰσί, καὶ τὴν ἄμμον;

Plato, Theaetetus 198c

“Shall we make counting nothing different from examining how great a number happens to be?”

Τὸ δὲ ἀριθμεῖν γε οὐκ ἄλλο τι θήσομεν τοῦ σκοπεῖσθαι πόσος τις ἀριθμὸς τυγχάνει ὤν.

Aristotle, On Indivisible Lines 96ba-b

“The thought of touching each point of an infinite series is not counting, if someone should imagine that the mind approaches infinity in this way. Perhaps this is impossible. For the movement of thought is not like the movement of things carried along in a continuous sequence. But, whatever the case, even if movement like this can happen, it is not counting. For counting needs discrete stopping points.”

Οὐδὲ δὴ τὸ καθ᾿ ἕκαστον ἅπτεσθαι τῶν ἀπείρων τὴν διάνοιαν οὐκ ἔστιν ἀριθμεῖν, εἰ ἄρα τις καὶ νοήσειεν οὕτως ἐφάπτεσθαι τῶν ἀπείρων τὴν διάνοιαν. ὅπερ ἴσως ἀδύνατον· οὐ γὰρ ἐν συνεχέσι
καὶ ὑποκειμένοις ἡ τῆς διανοίας κίνησις, ὥσπερ ἡ τῶν φερομένων.
Εἰ δ᾿ οὖν καὶ ἐγχωρεῖ κινεῖσθαι οὕτως, οὐκ ἔστι τοῦτο ἀριθμεῖν· τὸ γὰρ ἀριθμεῖν ἐστὶ τὸ μετὰ ἐπιστάσεως.

Plotinus, Ennead 1.1

“But how do we have God? For he travels on the true nature of thought and reality as it really is. Here is we we come to meet him, in the third lot counted from him. As Plato says, “from the undivided above” and from those things that are divided into bodies.

We need to imagine this portion of the soul as also divided into bodies and that it supplies itself in part as the size of the bodies in relations to how much each living thing is proportionally, since it gives itself to everything, even though it is one….”

Τὸν δὲ θεὸν πῶς; Ἢ ὡς ἐποχούμενον τῇ νοητῇ φύσει καὶ τῇ οὐσίᾳ τῇ ὄντως, ἡμᾶς δὲ ἐκεῖθεν τρίτους ἐκ τῆς ἀμερίστου, φησί, τῆς ἄνωθεν καὶ ἐκ τῆς περὶ τὰ σώματα μεριστῆς, ἣν δὴ δεῖ νοεῖν οὕτω μεριστὴν περὶ τὰ σώματα, ὅτι δίδωσιν ἑαυτὴν τοῖς σώματος μεγέθεσιν, ὁπόσον ἂν ζῷον ᾖ ἕκαστον, ἐπεὶ καὶ τῷ παντὶ ὅλῳ, οὖσα μία·
