Intelligence Squared, the organization that convenes debates on major intellectual and policy issues, is holding one at Yale on March 1st, devoted to the proposition that “Free speech is threatened on campus.” Intelligence Squared (IS) is founded on the same assumption as Heterodox Academy: the notion that better thinking is likely to emerge from a civil encounter between sharply differing viewpoints. So it’s appropriate that one of the four debaters is John McWhorter (the other three are Wendy Kaminer, Shaun Harper, and Jason Stanley). As the debate set-up asks: “Are the protestors silencing free speech, or are they just trying to be heard? And are the universities responding by defending free speech, or by suppressing it?” IS streams the debate live and then archives a podcast version afterward.
