“Has not one of the poets said that a noble friend is the best gift and a noble enemy the next best?”

“Never forget that when we are dealing with any pleasure in its healthy and normal and satisfying form, we are, in a sense, on the Enemy’s (God’s) ground…He [God] made the pleasure: all our research so far has not enabled us to produce one. All we can do is to encourage the humans to take the pleasures which our Enemy [God] has produced, at at times, or in ways, or in degrees, which He [God] has forbidden. ”

“The universe rings true whenever you fairly test it.”

“How many hours are there in a mile? Is yellow square or round? Probably half the questions we ask-half our great theological and metaphysical problems-are like that.”

“Don't shine so others can see you. Shine so that through you, others can see Him.”

“While friendship has been by far the chief source of my happiness, acquaintance or general society has always meant little to me, and I cannot quite understand why a man should wish to know more people than he can make real friends of.”

“When once a man is launched on such an adventure as this, he must bid farewell to hopes and fears, otherwise death or deliverance will both come too late to save his honor and his reason. Ho, my beauties!”

“God created things which had free will. That means creatures which can go wrong or right. Some people think they can imagine a creature which was free but had no possibility of going wrong, but I can't. If a thing is free to be good it's also free to be bad. And free will is what has made evil possible. Why, then, did God give them free will? Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having. A world of automata -of creatures that worked like machines- would hardly be worth creating. The happiness which God designs for His higher creatures is the happiness of being freely, voluntarily united to Him and to each other in an ecstasy of love and delight compared with which the most rapturous love between a man and a woman on this earth is mere milk and water. And for that they've got to be free. Of course God knew what would happen if they used their freedom the wrong way: apparently, He thought it worth the risk. (...) If God thinks this state of war in the universe a price worth paying for free will -that is, for making a real world in which creatures can do real good or harm and something of real importance can happen, instead of a toy world which only moves when He pulls the strings- then we may take it it is worth paying.”
