When a soldier complains of his hard life (or a labourer, etc.) try giving him nothing to do. - 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.

What would you say of that man who was made king by the error of the people, if he had so far forgotten his natural condition as to imagine that this kingdom was due to him, that he deserved it, and that it belonged to him of right? You would marvel at his stupidity and folly. But is there less in the people of rank who live in so strange a forgetfulness of their natural condition?

When we wish to correct with advantage, and to show another that he errs, we must notice from what side he views the matter, for on that side it is usually true, and admit that truth to him, but reveal to him the side on which it is false. He is satisfied with that, for he sees that he was not mistaken, and that he only failed to see all sides. Now, no one is offended at not seeing everything; but one does not like to be mistaken, and that perhaps arises from the fact that man naturally cannot see everything, and that naturally he cannot err in the side he looks at, since the perceptions of our senses are always true.
