Notre durée vaine et chétive - Blaise Pascal

We are generally the better persuaded by the reasons we discover ourselves than by those given to us by others.

[How does it happen that this man, so distressed at the death of his wife and his only son, or who has some great lawsuit which annoys him, is not at this moment sad, and that he seems so free from all painful and disquieting thoughts? We need not wonder; for a ball has been served him, and he must return it to his companion. He is occupied in catching it in its fall from the roof, to win a game. How can he think of his own affairs, pray, when he has this other matter in hand? Here is a care worthy of occupying this great soul, and taking away from him every other thought of the mind. This man, born to know the universe, to judge all causes, to govern a whole state, is altogether occupied and taken up with the business of catching a hare.

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.
