[Unbelievers] think they have made great efforts to get at the truth when they have spent a few hours in reading some book out of Holy Scripture, and have questioned some cleric about the truths of the faith. After that, they boast that they have searched in books and among men in vain.

The heart has its reasons of which reason knows nothing. We feel it in a thousand things. I say that the heart naturally loves the Universal Being, and naturally loves itself; and it gives itself to one or the other, and hardens itself against one or the other, as it chooses...it is the heart that feels God, not the reason; this is faith.

Those who are clever in imagination are far more pleased with themselves than prudent men could reasonably be.

The pagans do not know God, and love only the earth. The Jews know the true God, and love only the earth. The Christians know the true God, and do not love the earth.

Since we cannot know all that there is to be known about anything, we ought to know a little about everything.

I do not admire a virtue like valour when it is pushed to excess, if I do not see at the same time the excess of the opposite virtue, as one does in Epaminondas, who displayed extreme valour and extreme benevolence. For otherwise it is not an ascent, but a fall. We do not display our greatness by placing ourselves at one extremity, but rather by being at both at the same time, and filling up the whole of the space between them.

Lord, help me to do great things as though they were little, since I do them with your power; And little things as though they were great, since I do them in your name!
