ἡ μὲν οὖν μονὰς ἀρχή τις ὑπόκει- ται τῆς τῶν ἄλλων ἀριθμῶν ἀπεργαστικὴ συστάσεως, ἡ δὲ δυὰς μήκους ἐστὶν ἀπεργαστική. καθάπερ γὰρ ἐπὶ τῶν γεωμετρικῶν ἀρχῶν (M III 19 sqq.) ὑπεδείξαμεν πρῶτον, τίς ἐστιν ἡ στιγμή, εἶτα μετ’ αὐτὴν ἡ γραμ- μὴ μῆκος ἀπλατές τυγχάνουσα, τὸν αὐτὸν τρόπον καὶ ἐπὶ τοῦ παρόντος ἡ μὲν μονὰς τὸν τῆς στιγμῆς ἐπέχει λόγον, ἡ δὲ δυὰς τὸν τῆς γραμμῆς καὶ τοῦ μήκους· πσθὲν γάρ ποι ἐχώρησεν ἡ διάνοια ταύτην ἐννοουμένη, τοῦτο δʼ ἦν μῆκος.

The unit, then, is posited as a principle productive of the constitution of the other numbers, while the dyad is productive of length. For just as, in treating the principles of geometry (M III 19 following), we first indicated what the point is, and then after it the line, which is length without breadth, so too in the present case the unit corresponds to the point, and the dyad to the line and length. For thought, in conceiving it, proceeded from somewhere to somewhere, and this was length.

L’unité est donc posée comme un principe qui produit la constitution des autres nombres, tandis que la dyade produit la longueur. En effet, comme nous l’avons montré à propos des principes géométriques (M III 19 sq.), vient d’abord le point, puis, après lui, la ligne, qui est une longueur sans largeur. De même ici, l’unité tient la place du point, et la dyade celle de la ligne et de la longueur. Car l’esprit, en concevant la dyade, est allé d’un lieu à un autre, et cela constituait une longueur.
