At age seven, John Rawls survived diphtheria, but his brother Bobby caught it from him and died. The next winter Rawls survived pneumonia and his brother Tommy died the same way. This episode argues that the survivor’s guilt from those losses, along with a stutter he carried for life, drove a man who would dedicate himself to the mechanics of fairness. It follows Rawls from a Baltimore childhood shaped by a suffragist mother, through an intensely religious period at Princeton, to infantry combat in the Pacific, the aftermath of Hiroshima, a refused order and demotion, and the collapse of his Christian faith.

From there the conversation unpacks the reclusive Harvard professor’s major works. A Theory of Justice in 1971 introduced the original position and the veil of ignorance, explained here through cutting a cake without knowing which slice you will get, along with the maximin rule, equal basic liberties, and the difference principle. Political Liberalism in 1993 tackled legitimacy in a permanently divided society through public reason and overlapping consensus. The Law of Peoples in 1999 surprised his followers by refusing to apply the difference principle globally, drawing criticism from Amartya Sen, while also setting out rules for just war and condemning the firebombing of civilian cities. The episode closes with his strokes, his death in 2002, the National Humanities Medal, protesters holding his book in Tiananmen Square, and a thought experiment about an AI trained on the veil of ignorance.
