Cass Sunstein is one of the most widely cited legal scholars of all time and among the most prolific writers working today. This year alone he has five books out, including Imperfect Oracle on the strengths and limits of AI and On Liberalism: In Defense of Freedom. In his second appearance on the show, he brings his characteristic intellectual range to exploring liberalism's present precariousness and AI's implications for law and speech. Tyler and Cass discuss whether liberalism is self-undermining or simply vulnerable to illiberal forces, the tensions in how a liberal immigration regime would work, whether new generations of liberal thinkers are emerging, if Derek Parfit counts as a liberal, Mill's liberal wokeism, the allure of Mises' "cranky enthusiasm for freedom," whether the central claim of The Road to Serfdom holds up, how to blend indigenous rights with liberal thought, whether AIs should have First Amendment protections, the argument for establishing a right not to be manipulated, better remedies for low-grade libel, whether we should have trials run by AI, how Bob Dylan embodies liberal freedom, Cass' next book about animal rights, and more.
