A Theory of Justice: The Musical is a musical comedy by Eylon Levy, Ramin Sabi, Tommy Peto and Toby Huelin. Billed as a "time-travelling romp through 2,500 years of political philosophy", the musical tells a fictionalised account of the writing of A Theory of Justice (1971), the classic philosophical treatise by the American political philosopher John Rawls. The real-life John Rawls' daughter Liz praised the musical as "perfect" and "amazing and witty" after watching the Edinburgh Fringe Festival production, saying it "far surpassed any expectations."
