You can be good for the mere sake of goodness; you cannot be bad for the mere sake of badness. You can do a kind action when you are not feeling kind and when it gives you no pleasure, simply because kindness is right; but no one ever did a cruel action simply because cruelty is wrong - only because cruelty is pleasant or useful to him, In other words, badness cannot succeed even in being bad in the same way in which goodness is good. Goodness is, so to speak, itself: badness is only spoiled goodness. And there must be something good first before it can be spoiled.
C. S. LewisThe mark of Friendship is not that help will be given when the pinch comes (of course it will) but that, having been given, it makes no difference at all.
C. S. LewisWhen the voice of your friend or the page of your book sinks into democratic equality with the pattern of the wallpaper, the feel of your clothes, your memory of last night, and the noises from the road, you are falling asleep. The highly selective consciousness enjoyed by fully alert men, with all its builded sentiments and consecrated ideals, has as much to be called real as the drowsy chaos, and more.
C. S. LewisChild, to say the very thing you really mean, the whole of it, nothing more or less or other than what you really mean; that's the whole art and joy of words.
