Note 126 — Chapter XXXIX · LEGES AND EPINOMIS.
Reading edition
Plato, Republ. iii. pp. 395-396, x. p. 605 B; Gorgias, p. 502 B; Legg. iv. p. 719 B.
Aristotle takes a view of tragedy quite opposed to that of Plato: he considers it as calculated to purge or purify the emotions of fear, compassion, &c. (Aristot. Poet. c. 13. Compare Politic. viii. 7, 9). Unfortunately the Poetica exist only as a fragment, so that his doctrine about κάθαρσις is only declared and not fully developed.
Rousseau (in his Lettre à d’Alembert Sur les Spectacles, p. 33 seq.) impugns this doctrine of Aristotle, and condemns theatrical representations, partly with arguments similar to those of Plato, partly with others of his own.
