"In this world, which is so plainly the antechamber of another, there are no happy men. The true division of humanity is between those who live in light and those who live in darkness. Our aim must be to diminish the number of the latter and increase the number of the former. That is why we demand education and knowledge."
"It is the essence of truth that it is never excessive. Why should it exaggerate? There is that which should be destroyed and that which should be simply illuminated and studied. How great is the force of benevolent and searching examination! We must not resort to the flame where only light is required."
