“Man must learn to know the universe precisely as it is, or he cannot successfully find his place in it. A man should therefore use his reasoning faculty in all matters involving truth, and especially as concerning his religion. He must learn to distinguish between truth and error.”

“The Duke would not pay for the works. He says that the Castle can never be taken. That is called hubris, Giacomo, the belief that you are never wrong. Believing you are never wrong is an error that afflicts great men. I have learned that to be right you must first be wrong many times. Without making errors--and learning from them--a man cannot find the truth.”

“Earth, stars, and the vastness of space; yesterday, today and tomorrow; and the endlessly increasing knowledge of the relation of forces, present an illimitable universe of numberless phenomena. Only in general outline can the universe be understood. In its infinite variety of expression, it wholly transcends the human mind... In the midst of this complexity man finds himself. As he progresses from childhood to manhood, and his slumbering faculties are awakened, he becomes more fully aware of the vastness of his universe and of the futility of hoping to understand it in detail. Nevertheless, conscious man cannot endure confusion. Out of the universal mystery he must draw at least the general, controlling laws that proclaim order in the apparent chaos; and especially is he driven, by his inborn and unalterable nature, to know if possible his own place in the system of existing things. ”

“He wants them to learn to walk and must therefore take away His hand.”

“A man follows the path laid out for him. He does his duty to God and his King. He does what he must do, not what pleases him. God's truth, boy, what kind of world would this be if every man did what pleased him alone? Who would plough the fields and reap the harvest, if every man had the right to say, 'I don't want to do that.' In this world there is a place for every man, but every man must know his place.”

“The error is this: it is proper for a creator to be optimistic, in the deepest, most basic sense, since the creator believes in a benevolent universe and functions on that premise. But it is an error to extend that optimism to other specific men. First, it's not necessary, the creator's life and the nature of the universe do not require it, his life does not depend on others. Second, man is a being with free will; therefore, each man is potentially good or evil, and it's up to him and only to him (through his reasoning mind) to decide which he wants to be. The decision will affect only him; it is not (and cannot and should not be) the primary concern of any other human being.”
