We know then the existence and nature of the finite, because we also are finite and have extension. We know the existence of the infinite and are ignorant of its nature, because it has extension like us, but not limits like us. But we know neither the existence nor the nature of God, because he has neither extension nor limits.

I know whom I have believed.

If ignorance were bliss, he'd be a blister

We must know where to doubt, where to feel certain, where to submit. He who does not do so, understands not the force of reason.

Imagination decides everything.

The heart has its reasons of which reason knows nothing.

The struggle alone pleases us, not the victory.
