"Wars always bring about a conservative reaction. They overwhelm and destroy patient and careful efforts to improve the condition of man. Nothing can be heard in the cannon's roar but the voice of might. All the safeguards laboriously built to preserve individual freedom and foster man's welfare are blown to pieces with shot and shell. In the presence of the wholesale slaughter of men the value of life is cheapened to the zero point. What is one life compared with the almost daily records of tens of thousands or more mowed down like so many blades of grass in a field? Building up a conception of the importance of life is a matter of slow growth and education; and the work of generations is shattered and laid waste by machine guns and gases on a larger scale than ever before. Great wars have been followed by an unusually large number of killings between private citizens and individuals. These killers have become accustomed to thinking in terms of slaying and death toward all opposition, and these have been followed in turn by the most outrageous legal penalties and a large increase in the number of executions by the state. It is perfectly clear that hate begets hate, force is met with force, and cruelty can become so common that its contemplation brings pleasure, when it should produce pain."
