Concepts, Conceptions, and Principles of Justice

G.A. Cohen argues that Rawlsian constructivism mistakenly conflates principles of justice with optimal rules of regulation, a confusion that arises out of how Rawls has us think about justice. I use the concepts/conceptions distinction to argue that while citizens may reasonably disagree about the substance and demands of justice, some principles convergence may be possible: we can agree upon regulative principles consistent with justice, as each of us understands it. Rawlian constructivism helps us find that principled convergence, and this too is a conception of justice
