If there is to be toleration in the world, one of the things taught in schools must be the habit of weighing evidence, and the practice of not giving full assent to propositions which there is no reason to believe true. For example, the art of reading the newspapers should be taught. The schoolmaster should select some incident which happened a good many years ago, and roused political passions in its day. He should then read to the school children what was said by the newspapers on one side, what was said by those on the other, and some impartial account of what really happened. He should show how, from the biased account of either side, a practised reader could infer what really happened, and he should make them understand that everything in newspapers is more or less untrue. The cynical scepticism which would result from this teaching would make the children in later life immune from those appeals to idealism by which decent people are induced to further the schemes of scoundrels. History should be taught in the same way. Napoleon’s campaigns of 1813 and 1814, for instance, might be studied in the _Moniteur_, leading up to the surprise which Parisians felt when they saw the Allies arriving under the walls of Paris after they had (according to the official bulletins) been beaten by Napoleon in every battle. In the more advanced classes, students should be encouraged to count the number of times that Lenin has been assassinated by Trotsky, in order to learn contempt for death. Finally, they should be given a school history approved by the Government, and asked to infer what a French school history would say about our wars with France. All this would be a far better training in citizenship than the trite moral maxims by which some people believe that civic duty can be inculcated. It must, I think, be admitted that the evils of the world are due to moral defects quite as much as to lack of intelligence. But the human race has not hitherto discovered any method of eradicating moral defects; preaching and exhortation only add hypocrisy to the previous list of vices. Intelligence, on the contrary, is easily improved by methods known to every competent educator. Therefore, until some method of teaching virtue has been discovered, progress will have to be sought by improvement of intelligence rather than of morals. One of the chief obstacles to intelligence is credulity, and credulity could be enormously diminished by instruction as to the prevalent forms of mendacity. Credulity is a greater evil in the present day than it ever was before, because, owing to the growth of education, it is much easier than it used to be to spread misinformation, and, owing to democracy, the spread of misinformation is more important than in former times to the holders of power. Hence the increase in the circulation of newspapers.
