Talkativeness

Talkativeness is the throne of vainglory, on which it loves to show itself and make a display. Talkativeness is a sign of ignorance, a door to slander, a guide to jesting, a servant of falsehood, the ruin of compunction, a creator and summoner of despondency, a precursor of sleep, the dissipation of recollection, the abolition of watchfulness, the cooling of ardor, the darkening of prayer.
