Aristotle quote: “We make war that we may live in peace.”

“And happiness is thought to depend on leisure; for we are busy that we may have leisure, and make war that we may live in peace.”

Aristotle book Nicomachean Ethics

“In this different kind of war, we may never sit down at a peace table. But make no mistake about it, we are winning, and we will win.”

George W. Bush (1946) 43rd President of the United States

“From time immemorial, people have talked about peace without achieving it. Do we simply lack enough experience? Though we talk peace, we wage war. Sometimes we even wage war in the name of peace.. . . War may be too much a part of history to be eliminated—ever.”

Elie Wiesel (1928–2016) writer, professor, political activist, Nobel Laureate, and Holocaust survivor

As quoted in "Is World Peace on the Horizon?", in The Watchtower (15 April 1991)

“We must be prepared to make the same heroic sacrifices for the cause of peace that we make ungrudgingly for the cause of war.”

Albert Einstein (1879–1955) German-born physicist and founder of the theory of relativity

“Make no mistake of it, we will live. We will be alive and we will walk and talk and eat and sing and laugh and feel and love and bear our children in tranquillity, in security, in decency, in peace. You plan the wars, you masters of men — plan the wars and point the way and we will point the gun.”

Dalton Trumbo book Johnny Got His Gun

Johnny Got His Gun (1938)
Context: Put the guns into our hands and we will use them. Give us the slogans and we will turn them into realities. Sing the battle hymns and we will take them up where you left off. Not one, not ten, not ten thousand, not a million, not ten millions, not a hundred millions but a billion, two billions of us all — the people of the world. We will have the slogans and we will have the hymns and we will have the guns and we will use them and we will live. Make no mistake of it, we will live. We will be alive and we will walk and talk and eat and sing and laugh and feel and love and bear our children in tranquillity, in security, in decency, in peace. You plan the wars, you masters of men — plan the wars and point the way and we will point the gun.

“But while we put our trust not on force but on a reign of law and the administration of justice, yet we know that the maintenance of peace can not but to a large extent be dependent upon our sentiments and desires,. In spite of all the treaties we may make and all the tribunals we may establish, unless we maintain a public opinion devoted to peace we can not escape the ravages of war. A determination to do right will be more effective than all our treaties and courts, all our armies and fleets. A peaceful people will have peace, but a warlike people can not escape war.”

Calvin Coolidge (1872–1933) American politician, 30th president of the United States (in office from 1923 to 1929)

1920s, Ways to Peace (1926)

“We may gain something in our quest for peace if we recognize at once that war is not an abnormality. In the truest sense, it is not the mere play of brute force. It is the expression of the insistent human will, inflexible in its purpose.
When we consider the inability to maintain a just peace attests to the failure of civilization itself, we may be less confident of the success of any artificial contrivances to prevent war.”

Charles Evans Hughes (1862–1948) American judge

The Pathway of Peace (1923)
Context: We may gain something in our quest for peace if we recognize at once that war is not an abnormality. In the truest sense, it is not the mere play of brute force. It is the expression of the insistent human will, inflexible in its purpose.
When we consider the inability to maintain a just peace attests to the failure of civilization itself, we may be less confident of the success of any artificial contrivances to prevent war. We must recognize that we are dealing with the very woof and warp of human nature. The war to end war has left its curse of hate, its lasting injuries, its breeding grounds of strife, and to secure an abiding peace appears to be more difficult than ever. There is no advantage to shutting our eyes to the facts; nor should we turn in disgust of panaceas to the counsel of despair. The pathway of peace is the longest and most beset with obstacles the human race has to tread; the goal may be distant, but we must press on.
