The philosopher Dietrich Bonhoeffer was executed by the Nazis just weeks before World War II ended. But before his death he left behind a chilling insight that may explain much of the chaos we see today. In a remarkable prison letter, Bonhoeffer argued that stupidity is more dangerous than evil, because stupid people cannot be reasoned with and can be easily manipulated by powerful leaders and dangerous ideas. In this gripping episode of The Laughing Philosopher, we explore Bonhoeffer’s life, his haunting “Theory of Stupidity,” and what it reveals about modern society. From conspiracy theories and bizarre beliefs to the rise of political and ideological extremism, Bonhoeffer predicted our age of misinformation, outrage, and blind tribalism. And if stupidity really is more dangerous than evil, what hope do we have of resisting it? This may be one of the most unsettling and important ideas you’ll ever hear.
