Sententiae

Sententiae, the nominative plural of the Latin word sententia, are brief moral sayings, such as proverbs, adages, aphorisms, maxims, or apophthegms taken from ancient or popular or other sources, often quoted without context.

Sententia, the nominative singular, also called a "sentence," is a kind of rhetorical proof. Through the invocation of a proverb, quotation, or witty turn of phrase during a presentation or conversation one may be able to gain the assent of the listener, who will hear a kind of non-logical, but agreed-upon "truth" in what you are saying.
