Then there is a third stage of belief, a further stage, and this belief makes man still greater. It is the belief of reason, and it means that one does not believe in any authority, nor in what everybody else believes, but that one has reasoned it out; that one sees reason in it. This belief is stronger still; for of the beliefs I have explained before one cannot give proof, but in this case one can stand up and say, "Yes, I have reasoned it out."
