We are constantly told that “history repeats itself.” But history can’t literally repeat itself. Every moment in history has different people, different governments, different technology, different economic situations, different circumstances. What we really observe are repeated patterns of human behavior. Centuries apart, people still respond to fear, ambition, humiliation, prosperity, greed, faith, tribal allegiance and the yearning for security in startlingly familiar ways. History is always in flux, but human nature evolves much more slowly. It is frequently believed that “History doesn’t repeat itself, but it often rhymes.” This phrase is typically credited to Mark Twain; however, there is no evidence that Twain ever said these precise words.
