Saint Augustine

"If you plan to build a tall house of virtues, you must first lay deep foundations of humility."

"Humility is the foundation of all the other virtues hence, in the soul in which this virtue does not exist there cannot be any other virtue except in mere appearance."

"Humility must accompany all our actions, must be with us everywhere; for as soon as we glory in our good works they are of no further value to our advancement in virtue."

"It is human to err, but it is devilish to remain willfully in error."

"If humility does not precede all that we do, our efforts are fruitless."
