Note 23 — B. — Aristotle’s Doctrine.

This is stated by Aristotle himself, Metaph. Γ. vi. p. 1011, a. 15: οἱ δ’ ἐν τῷ λόγῳ τὴν βίαν μόνον ζητοῦντες ἀδύνατον ζητοῦσιν· ἐναντία γὰρ εἰπεῖν ἀξιοῦσιν, εὐθὺς ἐναντία λέγοντες. He here, indeed, applies this observation immediately to the Protagoreans, against whom it does not tell, instead of the Herakleiteans, against whom it does tell. The whole of the reasoning in this part of the Metaphysica is directed indiscriminately, and in the same words, against Protagoreans and Herakleiteans.
