8. Ἀλλὰ πῶς φησιν ὀκτὼ σφαιρῶν οὐσῶν ἑπτἀ λέγοται εἶναι οἱ φθόγγοι; ἢ ὅτι ἡ μὲν ἀεὶ κατὰ τὰ αὐτὰ κινουμένη ἀδιάφορον καὶ μίαν ποιεῖται τοῦ φθόγγου τὴν ἐκφώνησιν· οὐκ ἔχουσα δὲ ἰσοταχῆ οὐδὲ παραπλησίαν ἄλλην, οὐδʼ ἂν ἐν ἁρμονίᾳ τάσσοιτο. οἱ δὲ δὴ τῶν πλανωμένων πολλὴν τὴν ἀνομοιότητα καὶ τὴν ἐναντίαν πρὸς αὐτὴν ἔχοντες ἐδείκνυτο κίνησιν τοσαύτην, ὅσην ἡ τοῦ αὐτοῦ πρὸς τὴν θατέρου. διὸ δὴ τὸν ἀπʼ αὐτῆς φθόγγον ἄρρητον εἴασαν.
