The truth about nature we discover with our brains. The truth about religion we discover with our hearts.

Nature has some perfections to show that she is the image of God, and some defects to show that she is only His image.

It is not from space that I must seek my dignity, but from the government of my thought. I shall have no more if I possess worlds. By space the universe encompasses and swallows me up like an atom; by thought I comprehend the world.

Unless we love the truth we cannot know it.

Man is equally incapable of seeing the nothingness from which he emerges and the infinity in which he is engulfed.

Man's sensitivity to the little things and insensitivity to the greatest are the signs of a strange disorder.

Instead of complaining that God had hidden himself, you will give Him thanks for having revealed so much of Himself.
