Mark Twain in Eruption: Hitherto Unpublished Pages About Men and Events (1940) edited by Bernard DeVoto
“We cannot forget what had happened and history should not repeat itself.”
As quoted in Pioneers of Modern China : Understanding the Inscrutable Chinese (2005) by Khoon Choy Lee
Context: Nobody would say the cowshed was heaven and nobody would say the inhuman torture of so many victims be called a revolution of the proletariat. … A museum should be established to remind China of the follies and disasters that had fallen from 1966 to 1976. We cannot forget what had happened and history should not repeat itself.
“Those who cannot learn from history are doomed to repeat it.”
“Unexpected events happen… always.”
