p. 100 b15 Καὶ ἡ μὲν ἀρχὴ τῆς ἀρχῆς εἴη ἄν.
[136] [603.5]
Εἰπὼν ἀρχὴν ἐπιστήμης εἶναι τὸν νοῦν, ἔχειν δὲ καὶ ἀρχὰς τῶν ἐπιστητῶν τὰς ἀμέσους προτάσεις, νῦν λέγει ὅτι ἡ μὲν ἀρχὴ τῆς ἐπιστήμης εἴη ἂν τῆς ἀρχῆς τῶν ἐπιστητῶν γνῶσις, ἡ δὲ πᾶσα ἐπιστήμη παντὸς τοῦ ἐπιστητοῦ· ὡς γὰρ ἡ ἀρχὴ πρὸς τὴν ἀρχήν, οὕτως τὸ πᾶν, οὗ ἡ ἀρχή, πρὸς τὸ πᾶν πρᾶγμα, οὗ τῆς ἀρχῆς ἦν ἡ τῆς ἐπιστήμης ἀρχὴ γνωστική τε καὶ θεωρητική.
