Bertrand Russell
“In the teaching of history, there should be no undue emphasis upon one’s own country. The history of wars should be a small part of what is taught. Much the more important part should be concerned with progress in the arts of civilization. War should be treated as murder is treated. It should be regarded with equal horror and with equal aversion. It will be said that boys under such a regimen will be soft and effeminate. It will be said that they will lose the manly virtues and will be destitute of courage. And all this will be said by Christians in spite of Christ’s teaching.
But, dreadful as it may appear, boys brought up in the old way will grow into quarrelsome men who will find a world without war unbearably tame. Only a new kind of education, inculcating a new set of moral values, will make it possible to keep a peaceful world in existence. In the future, there will, after all, be plenty of opportunities for adventure, even dangerous adventure. Boys can go to the Antarctic for their holidays, and young men can go to the moon. There are many ways of showing courage without having to kill other people, and it is such ways that should be encouraged.”
