It is the heart which perceives God and not the reason.

Belief is a wise wager. Granted that faith cannot be proved, what harm will come to you if you gamble on its truth and it proves false? If you gain, you gain all; if you lose, you lose nothing. Wager, then, without hesitation, that He exists.

The heart has its reasons, which Reason does not know. We feel it in a thousand things. It is the heart which feels God, and not Reason. This, then, is perfect faith: God felt in the heart.

So we can only know God well by knowing our iniquities. Therefore those who have known God, without knowing their wretchedness, have not glorified Him, but have glorified themselves.

On the occasions when I have pondered over men's various activities, the dangers and worries they are exposed to at Court or at war, from which so many quarrels, passions, risky, often ill-conceived actions and so on are born, I have often said that man's unhappiness springs from one thing alone, his incapacity to stay quietly in one room.

Man's greatness lies in his power of thought.

I know whom I have believed.
