Musar sobre Provérbios 9:7

The third type is the one who scoffs at things, although he has no intention to humiliate those who do them. Yet by his scoffing he hinders work that has hope of success and might be achieved. This type of scoffer is wise in his own eyes, and everything that he himself has not begun he considers folly and mocks it. This trait can even lead him to heresy, mocking the Commandments themselves, as it is written, "The proud have had me greatly in derision; yet have I not turned aside from Thy law" (Ps. 119:51). And this type of a scoffer does not accept rebuke, as it is said, "Reprove not a scorner, lest he hate thee" (Prov. 9:8). And it is said, "He that correcteth a scorner getteth to himself shame" (Prov. 9:7). And inasmuch as he is wise in his own eyes he mocks the work of another man, and this is a trait for which there is no hope, as it is said, "Seest thou a man wise in his own eyes? There is more hope of a fool than of him" (Prov. 26:12).
