In The Politics of Petulance Alan Wolfe argues the core of our problem isn't Trump himself-it's that we are mired in an age of political immaturity. That immaturity is not grounded in any one ideology, nor is it a function of age or education. In 2016, many Americans were offered tantalizingly simple answers to complicated problems, and, like children being offered a lunch of Pop Rocks and Coke, they reflexively-and mindlessly-accepted. The good news is that we've been here before. Wolfe reminds us that we know how to grow up and face down Trump and other demagogues. Wolfe reinvigorates the tradition of public engagement exemplified by mid-century intellectuals such as Richard Hofstadter, Reinhold Niebuhr, and Lionel Trilling-and he draws lessons from their battles with McCarthyism and conspiratorial paranoia. Wolfe mounts a powerful case that we can learn from them to forge a new path for political intervention today. Wolfe has been thinking and writing about American life and politics for decades. He sees this moment as one of real risk. But he's not throwing up his hands; he's bracing us. We've faced demagogues before. We can find the intellectual maturity to fight back. Yes we can.
