50a5 Μὴ λανθανέτω δ᾽ ἡμᾶς ὅτι ἐν τῶι αὐτῶι συλλογισμῶι οὐχ ἅπαντα τὰ συμπεράσματα δι᾽ ἑνὸς σχήματός ἐστιν, ἀλλὰ τὸ μὲν διὰ τούτου τὸ δὲ δι᾽ ἄλλου. δῆλον οὖν ὅτι καὶ τὰς ἀναλύσεις οὕτω ποιητέον. ἐπεὶ δ᾽ οὐ πᾶν πρόβλημα ἐν ἅπαντι σχήματι ἀλλ᾽ ἐν ἑκάστωι τεταγμένα, φανερὸν ἐκ τοῦ συμπεράσματος ἐν ὧι σχήματι ζητητέον.	Non lateat autem nos, quoniam in eodem syllogismo, non omnes conclusiones per unam eamdem figuram sunt, sed haec quidem per hanc, illa vero per aliam. Palam ergo quoniam et resolutiones sic faciendum. Quoniam autem non omne propositum in omni figura, sed in unaquaque disposita sunt, manifestum est ex conclusione in qua figura sit quaerendum.	We should not forget that in the same syllogism not all conclusions are reached through one figure, but one through one figure, another through another. Clearly then we must analyse arguments in accordance with this. Since not every problem is proved in every figure, but certain problems in each figure, it is clear from the conclusion in what figure the premisses should be sought.
