Équilibre réflexif

Reflective equilibrium is a state of balance or coherence among a set of beliefs arrived at by a process of deliberative mutual adjustment among general principles and particular judgements. Although he did not use the term, philosopher Nelson Goodman introduced the method of reflective equilibrium as an approach to justifying the principles of inductive logic (this is now known as Goodman's method). The term reflective equilibrium was coined by John Rawls and popularized in his A Theory of Justice as a method for arriving at the content of the principles of justice. Dietmar Hübner has pointed out that there are many interpretations of reflective equilibrium that deviate from Rawls' method in ways that reduce the cogency of the idea. Among these misinterpretations, according to Hübner, are definitions of reflective equilibrium as "(a) balancing theoretical accounts against intuitive convictions; (b) balancing general principles against particular judgements; (c) balancing opposite ethical conceptions or divergent moral statements". Rawls argues that human beings have a "sense of justice" that is a source of both moral judgment and moral motivation. In Rawls's theory, we begin with "considered judgments" that arise from the sense of justice. These may be judgments about general moral principles (of any level of generality) or specific moral cases. If our judgments conflict in some way, we proceed by adjusting our various beliefs until they are in "equilibrium", which is to say that they are stable, not in conflict, and provide consistent practical guidance. Rawls argues that a set of moral beliefs in ideal reflective equilibrium describes or characterizes the underlying principles of the human sense of justice. For example, suppose that Zachary believes in the general principle of always obeying the commands in the Bible. Suppose also that he thinks that it is not ethical to stone people to death merely for being Wiccan. These views may come into conflict (see Exodus 22:18 versus John 8:7).
