The heart has its reasons which reason knows nothing of... We know the truth not only by the reason, but by the heart.

The heart has its reasons which reason knows not of.

The virtue of a man ought to be measured not by his extraordinary exertions, but by his every-day conduct.

This is what I see and what troubles me. I look on all sides, and I see only darkness everywhere. Nature presents to me nothing which is not matter of doubt and concern. If I saw nothing there which revealed a Divinity, I would come to a negative conclusion; if I saw everywhere the signs of a Creator, I would remain peacefully in faith. But, seeing too much to deny and too little to be sure, I am in a state to be pitied; wherefore I have a hundred time wished that if a God maintains nature, she should testify to Him unequivocally, and that, if the signs she gives are deceptive, she should suppress them altogether; that she should say everything or nothing, that I might see which cause I ought to follow. Whereas in my present state, ignorant of what I am or of what I ought to do, I know neither my condition nor my duty. My heart inclines wholly to know where is the true good, in order to follow it; nothing would be too dear to me for eternity.
