That passion may not harm us, let us act as if we had only eight hours to live. — Blaise Pascal

Man is only a subject full of error, natural and ineffaceable, without grace. Nothing shows him the truth. Everything deceives him. These two sources of truth, reason and the senses, besides being both wanting in sincerity, deceive each other in turn. The senses mislead the reason with false appearances, and receive from reason in their turn the same trickery which they apply to her; reason has her revenge. The passions of the soul trouble the senses, and make false impressions upon them. They rival each other in falsehood and deception.

The eternal silence of these infinite spaces frightens me.

Men never do evil so completely and cheerfully as when they do it from religious conviction.
