There are two simple principles which, if they were adopted, would solve almost all social problems. The first is that education should have for one of its aims to teach people only to believe propositions when there is some reason to think that they are true. The second is that jobs should be given solely for fitness to do the work. To take the second point first. The habit of considering a man’s religious, moral, and political opinions before appointing him to a post or giving him a job is the modern form of persecution, and it is likely to become quite as efficient as the Inquisition ever was. The old liberties can be legally retained without being of the slightest use. If, in practice, certain opinions lead a man to starve, it is poor comfort to him to know that his opinions are not punishable by law. There is a certain public feeling against starving men for not belonging to the Church of England, or for holding slightly unorthodox opinions in politics. But there is hardly any feeling against the rejection of Atheists or Mormons, extreme communists, or men who advocate free love. Such men are thought to be wicked, and it is considered only natural to refuse to employ them. People have hardly yet waked up to the fact that this refusal, in a highly industrial State, amounts to a very rigorous form of persecution. If this danger were adequately realized, it would be possible to rouse public opinion, and to secure that a man’s beliefs should not be considered in appointing him to a post. The protection of minorities is vitally important; and even the most orthodox of us may find himself in a minority some day, so that we all have an interest in restraining the tyranny of majorities. Nothing except public opinion can solve this problem. Socialism would make it somewhat more acute, since it would eliminate the opportunities that now arise through exceptional employers. Every increase in the size of industrial undertakings makes it worse, since it diminishes the number of independent employers. The battle must be fought exactly as the battle of religious toleration was fought. And as in that case, so in this, a decay in the intensity of belief is likely to prove the decisive factor. While men were convinced of the absolute truth of Catholicism or Protestantism, as the case might be, they were willing to persecute on account of them. While men are quite certain of their modern creeds, they will persecute on their behalf. Some element of doubt is essential to the practice, though not to the theory, of toleration. And this brings me to my other point, which concerns the aims of education.
