Othello 2.1: 195
... devil? When the blood is made dull with the act of sport, there should be, again to inflame it and to give satiety a fresh appetite, loveliness in favor, sympathy in years, manners, and beauties — all which the Moor is defective in. Now for want of these requir’d conveniences, her delicate tenderness will find itself abus’d, begin to heave the gorge, disrelish and abhor the Moor; very nature will instruct her in it and compel her to some second choice. Now, sir, this granted (as it is a most pregnant and unforc’d position), who stands so eminent in the degree of this fortune as Cassio does? A knave very voluble; no further conscionable than in putting on the mere form of civil and humane seeming, for the better compass of his salt and most hidden loose affection? Why, none, why, none — a slipper and subtle knave, a finder-out of occasion; that has an eye can stamp and counterfeit advantages, though true advantage never present itself; a devilish knave. Besides, the knave is handsome, young, and hath all those requisites in him that folly and green minds look after; a pestilent complete knave, and the woman hath found him already.
