Justice: What's the Right Thing to Do

by Michael J. Sandel

If moral reflection consists in seeking a fit between the judgments we make and the principles we affirm, how can such reflection lead us to justice, or moral truth? Even if we succeed, over a lifetime, in bringing our moral intuitions and principled commitments into alignment, what confidence can we have that the result is anything more than a self-consistent skein of prejudice? The answer is that moral reflection is not a solitary pursuit but a public endeavor. It requires an interlocutor—a friend, a neighbor, a comrade, a fellow citizen. Sometimes the interlocutor can be imagined rather than real, as when we argue with ourselves. But we cannot discover the meaning of justice or the best way to live through introspection alone. In Plato’s Republic, Socrates compares ordinary citizens to a group of prisoners confined in a cave. All they ever see is the play of shadows on the wall, a reflection of objects they can never apprehend. Only the philosopher, in this account, is able to ascend from the cave to the bright light of day, where he sees things as they really are. Socrates suggests that, having glimpsed the sun, only the philosopher is fit to rule the cave dwellers, if he can somehow be coaxed back into the darkness where they live. Plato’s point is that to grasp the meaning of justice and the nature of the good life, we must rise above the prejudices and routines of everyday life. He is right, I think, but only in part. The claims of the cave must be given their due. ...
