LOGIC.

Ὑμεῖ; μέντοι ἂν ἐμοὶ πείθησθε, σμικρὸν φροντίσαντες Σωκράτους, τῆς δὲ ἀληθείας πολὺ μᾶλλον, ἐὰν μέν τι ὑμῖν δοκῶ ἀληθὲς λέγειν, ξυνομολογήσατε, εἰ δὲ μὴ, παντὶ λόγῳ ἀντιτείνατε.

Socrates apud Platonem.

Τούτων δὲ τὰ μὲν πολλοὶ καὶ παλαιοὶ λέγουσιν, τὰ δὲ ὀλίγοι καὶ ἔνδοξοι ἄνδρες· οὐδετέρους δὲ τούτων εὔλογον διαμαρτάνειν τοῖς ὅλοις, ἀλλ ̓ ἕν γέ τι ἢ καὶ τὰ πλεῖστα κατορθοῦν.

Aristoteles.

in

Intelligitur, quod ars illa, quae dividit genera species et species in genera resolvit, quae διαλεκτική dicitur, non ab humanis machinationibus sit facta, sed in natura rerum ab auctore omnium artium, quae vere artes sunt, condita et a sapientibus inventa et ad utilitatem solerti rerum indagine usitata.

Johannes Scotus (Erigena).

Nam normae illae: experientia, principia, intellectus consequentiae, sunt revera vox divina.

Philippus Melanchthon.
