For after all what is man in nature? A nothing in relation to infinity, all in relation to nothing, a central point between nothing and all and infinitely far from understanding either.

He is equally incapable of seeing the nothingness out of which he was drawn and the infinite in which he is engulfed.

It is a dangerous experiment to call in gratitude as an ally to love. Love is a debt which inclination always pays, obligation never.

True eloquence makes light of eloquence, true morality makes light of morality; that is to say, the morality of the judgment, which has no rules, makes light of the morality of the intellect.... To make light of philosophy is to be a true philosopher.

Let us imagine a number of men in chains and all condemned to death, where some are killed each day in the sight of the others, and those who remain see their own fate in that of their fellows and wait their turn, looking at each other sorrowfully and without hope.

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.

The great mass of people judge well of things, for they are in natural ignorance, which is man's true state.
