Note 183 — IV.
Reading edition
Topic. IV. iv. p. 125, b. 6: οἷον εἰ τὴν μνήμην μονὴν ἐπιστήμης εἶπεν. πᾶσα γὰρ μονὴ ἐν τῷ μένοντι καὶ περὶ ἐκεῖνο, ὥστε καὶ ἡ τῆς ἐπιστήμης μονὴ ἐν τῇ ἐπιστήμῃ. ἡ μνήμη ἄρα ἐν τῇ ἐπιστήμῃ, ἐπειδὴ μονὴ τῆς ἐπιστήμης ἐστίν. τοῦτο δ’ οὐκ ἐνδέχεται· μνήμη γὰρ πᾶσα ἐν ψυχῇ. A definition similar to this is found in the Kratylus of Plato, p. 437, B.: ἔπειτα δὲ ἡ μνήμη παντί που μηνύει ὅτι μονή ἐστιν ἐν τῇ ψυχῇ, ἀλλ’ οὐ φορά.
