Again, Christianity asserts that every individual human being is going to live for ever, and this must be either true or false. Now there are a good many things which would not be worth bothering about if I were going to live only seventy years, but which I had better bother about very seriously if I am going to live for ever. Perhaps my bad temper or my jealousy are gradually getting worseso gradually that the increase in seventy years will not be very noticeable. But it might be absolute hell in a million years: in fact, if Christianity is true, Hell is the precisely correct technical term for what it would be. And immortality makes this other difference, which, by the by, has a connection with the difference between totalitarianism and democracy. If individuals live only seventy years, then a state, or a nation, or a civilisation, which may last for a thousand years, is more important than an individual. But if Christianity is true, then the individual is not only more important but incomparably more important, for he is everlasting and the life of a state or a civilisation, compared with his, is only a moment.
It seems, then, that if we are to think about morality, we must think of all three departments: relations between man and man: things inside each man: and relations between man and the power that made him. We can all co-operate in the first one. Disagreements begin with the second and become more serious with the third. It is dealing with the third that the main differences between Christian and non-Christian morality come out. For the rest of this book I am going to assume the Christian point of view, and look at the whole picture as it will be if Christianity is true.
2 THE CARDINAL VIRTUES
If you are allowed to talk for only ten minutes, pretty well everything else has to be sacrificed to brevity. One of my chief reasons for dividing morality up into three parts (with my picture of the ships sailing in convoy) was that this seemed the shortest way of covering the ground. Here I want to give some idea of another way in which the subject has been divided by old writers, which was too long to use in my talk, but which is a very good one.
According to this longer scheme there are seven virtues. Four of them are called Cardinal virtues, and the remaining three are called Theological virtues. The Cardinal ones are those which all civilised people recognise: the Theological are those which, as a rule, only Christians know about. I shall deal with the Theological ones later on: at present I am talking about the four Cardinal virtues. (The word cardinal has nothing to do with Cardinals in the Roman Church. It comes from a Latin word meaning the hinge of a door. These were called cardinal virtues because they are, as we should say, pivotal.) They are PRUDENCE, TEMPERANCE, JUSTICE AND FORTITUDE.
Prudence means practical common sense, taking the trouble to think out what you are doing and what is likely to come of it. Nowadays most people hardly think of Prudence as one of the virtues. In fact, because Christ said we could only get into His world by being like children, many Christians have the idea that, provided you are good, it does not matter being a fool. But that is a misunderstanding.
In the first place, most children show plenty of prudence about doing the things they are really interested in, and think them out quite sensibly. In the second place, as St Paul points out, Christ never meant that we were to remain children in intelligence: on the contrary. He told us to be not only as harmless as doves, but also as wise as serpents. He wants a childs heart, but a grown-ups head. He wants us to be simple, single-minded, affectionate, and teachable, as good children are; but He also wants every bit of intelligence we have to be alert at its job, and in first-class fighting trim. The fact that you are giving money to a charity does not mean that you need not try to find out whether that charity is a fraud or not. The fact that what you are thinking about is God Himself (for example, when you are praying) does not mean that you can be content with the same babyish ideas which you had when you were a five-year-old. It is, of course, quite true that God will not love you any the less, or have less use for you, if you happen to have been born with a very second-rate brain. He has room for people with very little sense, but He wants every one to use what sense they have. The proper motto is not Be good, sweet maid and let who can be clever, but Be good, sweet maid, and dont forget that this involves being as clever as you can. God is no fonder of intellectual slackers than of any other slackers. If you are thinking of becoming a Christian, I warn you, you are embarking on something which is going to take the whole of you, brains and all. But, fortunately, it works the other way round. Anyone who is honestly trying to be a Christian will soon find his intelligence being sharpened: one of the reasons why it needs no special education to be a Christian is that Christianity is an education itself. That is why an uneducated believer like Bunyan was able to write a book that has astonished the whole world.
