Consider judicial decisionmaking. In one imaginable system, a judge simply decides a case so as to yield what she thinks is the best or preferable result in that particular case. Another system of judicial decision involves principled decision: a common law judge is to formulate a principle to fit (most or almost all) precedents and a range of hypothetical cases, and then use this principle to decide the current case.* The attempt to formulate an acceptable general principle is a test of your judgment about the particular case: is there some adequate general principle—a principle that gives the right result in all established cases and obvious hypothetical ones—that also yields the result you want in this case? If you cannot find such a principle, reconsider what result you do want in this case.
Such a procedure is a test of a particular judgment on the assumption that any correct judgment is yielded by some true acceptable gen____________________
