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. LewisGood philosophy must exist, if for no other reason, because bad philosophy needs to be answered.
C. S. LewisTalk to me about the truth of religion and I'll listen gladly. Talk to me about the duty of religion and I'll listen submissively. But don't come talking to me about the consolations of religion or I shall suspect that you don't understand.
C. S. LewisAnyone who endeavors to be a Christian will soon find his intelligence being sharpened. You are embarking on something that is going to take the whole of you, brains and all.
