There are three sources of belief: reason, custom, inspiration. - Blaise Pascal

We desire truth and find in ourselves nothing but uncertainty.
We seek happiness and find only wretchedness and death.
We are incapable of not desiring truth and happiness and incapable of either certainty or happiness.
We have been left with this desire as much as a punishment as to make us feel how far we have fallen.

Cuando no se ama demasiado no se ama lo suficiente

We naturally believe we are more capable of reaching the centre of things than of embracing their circumference, and the visible extent of the world is visibly greater than we. But since we in our turn are greater than small things, we think we are more capable of mastering them, and yet it takes no less capacity to reach nothingness than the whole. In either case it takes an infinite capacity, and it seems to me that anyone who had understood the ultimate principles of things might also succeed in knowing infinity. One depends on the other, and one leads to the other. These extremes touch and join by going in opposite directions, and they meet in God and God alone.
