It [Christianity] is not a philosophy because, being a vision, it is not a pattern but a picture. It is not one of those simplifications which resolve everything into an abstract explanation; as that everything is recurrent; or everything is relative; or everything is inevitable; or everything is illusive. It is not a process but a story. It has proportions, of the sort seen in a picture or a story; it has not the regular repetitions of a pattern or a process; but it replaces them by being convincing as a picture or a story is convincing. In other words, it is exactly, as the phrase goes, like life. For indeed it is life.
G.K. Chesterton, The Everlasting Man
