History does not repeat itself, but it rhymes. This quote has been attributed to Mark Twain, but there seems no good evidence he coined it. Instead, it appears that psychoanalyst Theodor Reik—an early student of Sigmund Freud—who fled Nazi Germany in the 1930s, crafted a line with a similar sentiment in a 1965 essay. In any event, this aphorism has been embraced by MSNBC host Rachel Maddow, who has often brought a historian’s perspective to the current events she examines on television. And this maxim is the mantra for her latest podcast, Rachel Maddow Presents: Ultra, which showcases an eerie similarity between the American fascist movement of the 1940s and the political extremism of the moment.
