Note 386 — CANTO XI.

Thy Ethics: The Ethics of Aristotle, in which it is said: ‘With regard to manners, these three things are to be eschewed: incontinence, vice, and bestiality.’ Aristotle holds incontinence to consist in the immoderate indulgence of propensities which under right guidance are adapted to promote lawful pleasure. It is, generally speaking, the sin of which those about whom Dante has inquired were guilty.—It has been ingeniously sought by Philalethes (Gött. Com.) to show that Virgil’s disquisition is founded on this threefold classification of Aristotle’s—violence being taken to be the same as bestiality, and malice as vice. But the reference to Aristotle is made with the limited purpose of justifying the lenient treatment of incontinence; in the same way as a few lines further on Genesis is referred to in support of the harsh treatment of usury.
