Few friendships would survive if each one knew what his friend says of him behind his back.

Our imagination so magnifies this present existence, by the power of continual reflection on it, and so attenuates eternity, by not thinking of it at all, that we reduce an eternity to nothingness, and expand a mere nothing to an eternity; and this habit is so inveterately rooted in us that all the force of reason cannot induce us to lay it aside.

It is of dangerous consequence to represent to man how near he is to the level of beasts, without showing him at the same time his greatness. It is likewise dangerous to let him see his greatness without his meanness. It is more dangerous yet to leave him ignorant of either; but very beneficial that he should be made sensible of both.

Without the knowledge of our wretchedness, the knowledge of God creates pride. With it, the knowledge of God creates despair. The knowledge of Christ offers a third way, because in him we find both God and our wretchedness.

Vanity is so anchored in the heart of man that a soldier, a soldier's servant, a cook, a porter brags and wishes to have his admirers. Even philosophers wish for them. Those who write against vanity want to have the glory of having written well; and those who read it desire the glory of having read it. I who write this have perhaps this desire, and perhaps those who will read it.

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. The ends of things and their beginnings are impregnably concealed from him in an impenetrable secret. He is equally incapable of seeing the nothingness out of which he was drawn and the infinite in which he is engulfed.
