The most important lesson I have learned from Spheres of Justice and related works by Michael Walzer is how much we gain as political theorists if we begin our theoretical reflections with ordinary moral discourse about public affairs—with the concrete judgements we make, the characteristic language we use, the particular principles we invoke, the specific problems we recognize, and the actual arguments we advance when we talk about questions of justice in ordinary life.
