"When I mention Figures, I must observe, that Men of critical Knowledge have justly distinguished between Figures of Speech, and Figures of the Sentiment; the former including Metaphor and all Translations of Phrases, and the latter consisting of such Breaks and Transitions in Discourse, as the Mind is known to make when under the Compunction of warring Passions."

The Repetition expresses the natural workings of the Mind, when other Ideas are awakened, and serve to excite a new Conflict of Passions. The use of these kind of Figures in Tragedy should be as free and bold as possible, and with Respect to Expression, no other Regard is to be paid to it, than to chuse such Words as may be most significantly picturesque, in order to have the more lively Effect on the Imagination, the Passions being then in a stronger Ferment when lively Images are presented to the Fancy.
