“We know the existence of the infinite without knowing its nature, because it too has extension but unlike us no limits.But we do not know either the existence or the nature of God, because he has neither extension nor limits.”

“We know that there is an infinite, and we know not its nature. As we know it to be false that numbers are finite, it is therefore true that there is a numerical infinity. But we know not of what kind; it is untrue that it is even, untrue that it is odd; for the addition of a unit does not change its nature; yet it is a number, and every number is odd or even (this certainly holds of every finite number). Thus we may quite well know that there is a God without knowing what He is.”

“Knowing God without knowing our wretchedness leads to pride. Knowing our wretchedness without knowing God leads to despair. Knowing Jesus Christ is the middle course, because in him we find both God and our wretchedness.”

“Reverend Fathers, my letters do not customarily follow one another so closely, nor are they usually so extensive. The little time I have had has caused both. I have made this one longer only because I have not had the leisure of making it shorter.”

“Man is only a reed, the weakest in nature, but he is a thinking reed. There is no need for the whole universe to take up arms to crush him: a vapour, a drop of water is enough to kill him. but even if the universe were to crush him, man would still be nobler than his slayer, because he knows that he is dying and the advantage the universe has over him. The universe knows none of this.”

“The only religion which is against nature, against common sense and against our pleasures is the only one which has always existed.”

“One has followed the other in an endless circle, for it is certain that as man's insight increases so he finds both wretchedness and greatness within himself. In a word man knows he is wretched. Thus he is wretched because he is so, but he is truly great because he knows it.”
