War has no longer the justification that it makes for the survival of the fittest; it involves the survival of the less fit. The idea that the strugg… - Norman Angell

As an Englishman, particularly as an Englishman standing upon foreign soil, I am, of course, prepared to argue that every war we have ever fought was a purely defensive war. But I am obliged to take cognizance of the quite simple historical fact that for about one thousand years, since the time indeed when Norwegians ravaged our coasts and a certain Scandinavian landed at Hastings in 1066, every war we have fought happens to have been fought in other people's countries. Now if defense means merely keeping burglars out of the house, what were we doing on all those occasions in other people's houses? Our history in this respect is not peculiar. The United States is proud of her remoteness from the old world, her freedom from entanglement in its quarrels, her isolation. Yet in her relatively very short history as an independent state she has fought at least six foreign wars while her troops have landed on foreign soil on nearly a hundred occasions. Not one of those wars was for the purpose of defending American soil.

Our daily life is no longer cursed by fear of those pestilences, plagues, black deaths, which used to devastate Europe. The layman has abolished those plagues by using the medical expert's knowledge. The medical expert has said in effect, "There are not many things that we are agreed upon, but at least we are agreed upon this: that though we cannot cure bubonic plague or cholera, we can prevent them, for we know that they are caused by microorganisms transmitted through water and vermin. Keep sewage from your drinking water and vermin from your homes, and you will prevent these plagues." The layman has seen the point, applied appropriate measures, and these dreadful pestilences have disappeared. Now, if our publics these last twenty years could have grasped certain social truths, not inherently more difficult to understand than the microbic theory of disease, a large part at least of the economic and political pestilences which have come upon us in our generation would not have arisen.

Man's greatest advances these last few generations have been made by the application of human intelligence to the management of matter. Now we are confronted by a more difficult problem, the application of intelligence to the management of human relations. Unless we can advance in that field also, the very instruments that man's intelligence has created may be the instruments of his destruction.
