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

The end point of rationality is to demonstrate the limits of rationality

[22] Flies are so mighty that they win battles, paralyse our minds, eat up our bodies.

He who does not see the vanity of the world is himself very vain. Indeed who do not see it but youths who are absorbed in fame, diversion, and the thought of the future? But take away diversion, and you will see them dried up with weariness. They feel then their nothingness without knowing it; for it is indeed to be unhappy to be in insufferable sadness as soon as we are reduced to thinking of self, and have no diversion.”

If our condition were truly happy, we would not need diversion from thinking of it in order to make ourselves happy.

As men are not able to fight against death, misery, ignorance, they have taken it into their heads, in order to be happy, not to think of them at all.

The only thing which consoles us for our miseries is diversion, and yet this it the greatest of our miseries. For it is this which principally hinders us from reflecting upon ourselves, and which makes us insensibly ruin ourselves. Without this we should be in a state of weariness, and this weariness would spur us to seek a more solid means of escaping from it. But diversion amuses us, and leads us unconsciously to death
