Nations that forget their history lack the power to create it.
Voltaire thought that history is the record of the crimes and absurdities of mankind. I thought that was a very unworthy definition. I should say history is the record of the activities of mankind and it has two sides — one is the crimes and absurdities and the other is the contributions to civilization, the lasting developments which enabled each generation to proceed with a larger heritage than the one before. And that to me is the meaning of history.
