‘Can’t you lead a good life without believing in Christianity?’ This is the question on which I have been asked to write, and straight away, before I begin trying to answer it, I have a comment to make. The question sounds as if it were asked by a person who said to himself, ‘I don’t care whether Christianity is in fact true or not. I’m not interested in finding out whether the real universe is more like what the Christians say than what the Materialists say. All I’m interested in is leading a good life. I’m going to choose beliefs not because I think them true but because I find them helpful.’ Now frankly, I find it hard to sympathize with this state of mind. One of the things that distinguishes man from the other animals is that he wants to know things, wants to find out what reality is like, simply for the sake of knowing. When that desire is completely quenched in anyone, I think he has become something less than human. As a matter of fact, I don’t believe any of you have really lost that desire. More probably, foolish preachers, by always telling you how much Christianity will help you and how good it is for society, have actually led you to forget that Christianity is not a patent medicine. Christianity claims to give an account of FACTS - to tell you what the real universe is like. Its account of the universe may be true, or it may not, and once the question is really before you, then your natural inquisitiveness must make you want to know the answer. If Christianity is untrue, then no honest man will want to believe it, however helpful it might be: if it is true, every honest man will want to believe it, even if it gives him no help at all.
