"But if the Torrents of sensual Love are permitted to descend from the Hills of credulous Hope, they may so swell the gentle Stream, as to make it difficult, if not impossible, to be retain'd in its usual Bounds."
— Richardson, Samuel (bap. 1689, d. 1761)
"But here, a dear Lady, having unhappily failed, is enabled to set her Foot in the new-made Breach, while yet it is possible to stop it, and to say, with little Variation, in the Language of that Power, [Page 432] which only could enable her to say it, Hither, ye proud Waves of dissolute Love, altho' you havecome, yet no farther shall ye come; is such an Instance of magnanimous Resolution, and Self-conquest, as is very rarely to be met with."
(III.63, pp. 431-2)
