"People like to think of war as a ‘social thunderstorm’. It is said that it ‘purifies’ the atmosphere; it has its great benefits -it ‘hardens the youth’ and makes them courageous. As far as that goes, people say, we have always had and will always have wars. They are biologically motivated. According to Darwin, the ‘struggle for existence’ is the law of life. Why, then, were peace conferences organized? Nor have I ever heard that bears or elephants split up into two camps and annihilate one another. In the animal kingdom there are no wars within the same species. Like sadism, war among one’s own kind is an acquisition of ‘civilised man'. No, for some reason or another, man shies away from putting his finger on the causes of war. And there can be no doubt that better ways than war exist of making youth fit and healthy, namely, a satisfying love life, pleasurable and steady work, general sports and freedom from the malicious gossip of old maids. In short, such arguments are hollow chatter."
