"Whoever guards his mouth and tongue keeps his soul from troubles." (Prov. 21:23) "A fool also multiplies words." (Eccl. 10:14) "A fool vents all his feelings, but a wise man holds them back." (Prov. 29:11) "In the multitude of words sin is not lacking, but he who restrains his lips is wise." (Prov. 10:19)

William Penn, leader of the early American colonists who eventually named their state of Pennsylvania in his honor, gave these rules regarding conversation:

"Some are so foolish as to interrupt and anticipate those that speak instead of hearing and thinking before they answer, which is uncivil, as well as silly.

"Consider both WHAT is fit, and WHEN it is fit, to speak.

"In all debates, let truth be thy aim, not victory or unjust interest; and endeavor to gain, rather to expose, thy antagonist."
