Aristotle, it is well known, was himself so very moral a character, that, not content with writing his Nichomachean Ethics, in one volume octavo, he also wrote another system, called Magna Moralia, or Big Ethics.

Naturalia, moralia, mathematica, liberales disciplinas, artiumque omnium peritiam callebat. 24. Nothing in nature's power to contrive of which he has not written. 25.

Reason was his tutor, and first principles his magna moralia.

Plutarchi Scripta Moralia, Graece et Latine: Parisiis, editore Ambrosio F. Didot, 1841.
