To seek the greatest good is to live well, and to live well is nothing other than to love God with the whole heart, the whole soul, and the whole mind: It is therefore obvious that this love must be kept whole and uncorrupt, that is temperance; it should not be overcome with difficulties, that is fortitude, it must not be subservient to anything else, that is justice; it must discriminate among things so as not to be deceived by falsity or fraud, that is prudence.
Saint AugustineFor why, my brothers and sisters, would you rejoice in silver? Either your silver will perish, or you will, and no one knows which will perish first. For neither can you remain here always, nor can silver remain here always; so also with gold, wardrobes, houses, money, real estate-and in the end, even the light by which we enjoy all these things. So do not be willing then to rejoice in such things as these. Rejoice instead in the light that has no setting; rejoice in the dawn which no yesterday precedes, and no tomorrow follows.
Saint AugustineEveryone who observes himself doubting observes a truth, and about that which he observes he is certain; therefore he is certain about a truth. Everyone therefore who doubts whether truth exists has in himself a truth on which not to doubt.... Hence one who can doubt at all ought not to doubt the existence of truth.
Saint Augustine
