C. S. LewisThe worldly man treats certain people kindly because he 'likes' them: the Christian, trying to treat every one kindly, finds him liking more and more people as he goes on - including people he could not even have imagined himself liking at the beginning.
C. S. LewisThe standard that measures two things is something different from either.
