John Adams on war and peace

I must study politics and war that my sons may have liberty to study mathematics and philosophy. My sons ought to study mathematics and philosophy, geography, natural history, naval architecture, navigation, commerce and agriculture in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry, and porcelain.

It must be felt that there is no national security but in the nation’s humble acknowledged dependence upon God and His overruling providence.

Great is the guilt of an unnecessary war.

The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Thomas Jefferson1743–1826Letter to William Stephens Smith (13 November 1787). Manuscript at the Library of Congress.

• Liberty

Every gun that is made, every warship launched, every rocket fired, signifies in the final sense a theft from those who hunger and are not fed, those who are cold and are not clothed.

Dwight D. Eisenhower1890–1969The Chance for Peace (1953)

• Guns

The object of war is not to die for your country but to make the other bastard die for his.

George S. Patton1885–1945
