Note 20 — Chapter XI · PHYSICA AND METAPHYSICA.
Reading edition
Aristot. Metaph. Γ. iii. p. 1005, b. 26; K. v. p. 1062, a. 32. Here Aristotle intimates that Herakleitus may have asserted what he did not believe; though we find him in another place citing Herakleitus as an example of those who adhered as obstinately to their opinions as other persons adhered to demonstrated truth (Ethic. Nik. VII. v. p. 1146, b. 30.).
