All the unhappiness of men arises from one single fact, that they cannot stay quietly in their own chamber.
Blaise PascalCuriosity is only vanity. Most frequently we wish not to know, but to talk. We would not take a sea voyage for the sole pleasure of seeing without hope of ever telling.
Blaise PascalHuman life is thus only a perpetual illusion; men deceive and flatter each other. No one speaks of us in our presence as he does of us in our absence. Human society is founded on mutual deceit; few friendships would endure if each knew what his friend said of him in his absence, although he then spoke in sincerity and without passion.
Blaise PascalWe know that there is an infinite, and we know not its nature. As we know it to be false that numbers are finite, it is therefore true that there is a numerical infinity. But we know not of what kind; it is untrue that it is even, untrue that it is odd; for the addition of a unit does not change its nature; yet it is a number, and every number is odd or even (this certainly holds of every finite number). Thus we may quite well know that there is a God without knowing what He is.
