“if you do one good deed your reward usually is to be set to do another and harder and better one.”

“He had not yet learned that sometimes your reward for doing one task well is to be set with a harder and better one.”

“And he writhed inside at what seemed the cruelty and unfairness of the demand. He had not yet learned that if you do one good deed your reward usually is to do another and harder and better one.”

“If you run now, without a moment's rest, you will still be in time to warn King Lune."Shasta's heart fainted at these words for he felt he had no strength left. And he writhed inside at what seemed the cruelty and unfairness of the demand. He had not yet learned that if you do one good deed your reward usually is to be set to do another and harder and better one. But all he said out loud was:"Where is the King?"The Hermit turned and pointed with his staff. "Look," he said. "There is another gate, right opposite to the one you entered by. Open it and go straight ahead: always straight ahead, over level or steep, over smooth or rough, over dry or wet. I know by my art that you will find King Lune straight ahead. But run, run: always run.”

“Now we cannot...discover our failure to keep God's law except by trying our very hardest (and then failing). Unless we really try, whatever we say there will always be at the back of our minds the idea that if we try harder next time we shall succeed in being completely good. Thus, in one sense, the road back to God is a road of moral effort, of trying harder and harder. But in another sense it is not trying that is ever going to bring us home. All this trying leads up to the vital moment at which you turn to God and say, "You must do this. I can't.”

“The Moral Law isn't any one instinct or any set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts. (...) The most dangerous thing you can do is to take any one impulse of your own nature and set it up as the thing you ought to follow at all costs. There's not one of them which won't make us into devils if we set it up as an absolute guide. You might think love of humanity in general was safe, but it isn't. If you leave out justice you'll find yourself breaking agreements and faking evidence in trials 'for the sake of humanity,' and become in the end a cruel and treacherous man.”

“Strictly speaking, there are no such things as good and bad impulses. Think...of a piano. It has not got two kinds of notes on it, the 'right' notes and the 'wrong' ones. Every single note is right at one time and wrong at another. The Moral Law is not any one instinct or set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts.”
