In The Origins of Totalitarianism, Arendt emphasized one primary factor in the rise of authoritarianism that has little obvious connection to politics: loneliness. While we usually think of loneliness as not having our social needs met, Arendt defined the word as something deeper. Loneliness happens when there are no shared objective facts and no potential collective action to solve shared challenges. It’s a state of being where you can’t trust others. Loneliness, in Arendt’s telling, inflames the connective tissues of a society. It weakens the body politic so that demagogues and despots can prey. “What prepares men for totalitarian domination,” she wrote, “… is the fact that loneliness, once a borderline experience usually suffered in certain marginal social conditions like old age, has become an everyday experience.”
