Those who do not learn from history are doomed to repeat it

Meaning: Ignoring past mistakes leads to repeating them.

Origin: The line comes from the philosopher George Santayana's The Life of Reason (1905), where it reads: "Those who cannot remember the past are condemned to repeat it." Santayana was arguing that progress depends on keeping what experience has taught. The line has been quoted so often, usually with "history" in place of "the past," that it now circulates as a proverb.
