“Nothing is very strong: strong enough to steal away a man's best years not in sweet sins but in a dreary flickering of the mind over it knows not what and knows not why, in the gratification of curiosities so feeble that the man is only half aware of them, in drumming of fingers and kicking of heels, in whistling tunes that he does not like, or in the long, dim labyrinth of reveries that have not even lust or ambition to give them a relish, but which, once chance association has started them, the creature is took weak and fuddled to shake off.”

“A moderately bad man knows he is not very good: a thoroughly bad man thinks he is alright. This is common sense really. You understand sleep when you are awake, not well you are sleeping.”

“There is nothing indulgent about the Moral Law. It is as hard as nails. It tells you to do the straight thing and it does not seem to care how painful, or dangerous, or difficult it is to do.”

“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.”

“The first action to be taken is to pull ourselves together. If we are going to be destroyed by an atomic bomb, let that bomb, when it comes, find us doing sensible and human things -- praying, working, teaching, reading, listening to music, bathing the children, playing tennis, chatting to our friends over a pint and a game of darts -- not huddled together like frightened sheep and thinking about bombs.”

“And there we all were, as invisible as you could wish to see.”

“Well, sir, if things are real, they’re there all the time." "Are they?" said the Professor; and Peter did not quite know what to say.”

“Everything becomes more and more itself. Here is joy that cannot be shaken. Our light can swallow up your darkness; but your darkness cannot now infect our light.”

“What we work out in our journals we don’t take out on family and friends.”

“One of the drawbacks about adventures is that when you come to the most beautiful places you are often too anxious and hurried to appreciate them.”

“Once when I had remarked on the affection quite often found between cat and dog, my friend replied, "Yes. But I bet no dog would ever confess it to the other dogs.”

“Thirst was made for water; inquiry for truth. What you now call the free play of inquiry has neither more nor less to do with the ends for which intelligence was given you than masturbation has to do with marriage.”

“If you do not take the distinction between good and bad very seriously, then it is easy to say that anything you find in this world is a part of God. But, of course, if you think some things really bad, and God really good, then you cannot talk like that. You must believe that God is separate from the world and that some of the things we see in it are contrary to His will.”

“The world is so much larger than I thought. I thought we went along paths--but it seems there are no paths. The going itself is the path.”

“Good and evil both increase at compound interest. That is why the little decisions you and I make every day are of such infinite importance. The smallest good act today is the capture of a strategic point from which, a few months later, you may be able to go on to victories you never dreamed of. An apparently trivial indulgence in lust or anger today is the loss of a ridge or railway line or bridgehead from which the enemy may launch an attack otherwise impossible.”
