16. We may persuade ourselves that we possess various virtues, because we have a tangible proof within us that we really have them. Thus we may judge ourselves to be chaste, because we feel really attracted to chastity; or we may think ourselves abstemious, because we are so by nature; or obedient, because we practice a ready obedience. But however much a man may exercise humility, he can never form any judgment as to his being really humble, for he who thinks himself humble is no longer so.

In the same way that to recognize that we are proud is the beginning of humility, so to flatter ourselves that we are humble is the beginning of pride, and the more humble we think ourselves the greater is our pride. That self-complacency which the heart feels, making us imagine that we are humble in consequence of some agreeable reflections we have had about ourselves, is a species of vanity; and how can vanity exist with humility which is founded solely on truth? Vanity is nothing but a lie, and it is precisely from a lie that pride springs.

Let us pray to God with the prophet: "Let not the foot of pride come to me." [Ps. xxxv, 12] Grant, O my God, that I may be humble, but that I may not know that I am humble. Make me holy, yet ignorant of holiness; for if I should learn to know or even to imagine myself holy, I should become vain; and through vanity should lose all humility and holiness.
