Justice without force is powerless; force without justice is tyrannical. - Blaise Pascal

We know the existence of the infinite without knowing its nature, because it too has extension but unlike us no limits.
But we do not know either the existence or the nature of God, because he has neither extension nor limits.

Happiness can be found neither in ourselves nor in external things, but in God and in ourselves as united to him.

Since we cannot know all that there is to be known about anything, we ought to know a little about everything.
