Sophisticated realists, uncompromising positivists, and postmodernists created much of the law in the last century. Judges, lawyers, and philosophers now are continuing to clarify, improve, and use the law. The law is often clear. But it can be indeterminate because it is indefinite, indistinct, or vague. Two examples are provided.

6. According to Leiter, “the Realists … do not claim that the law is ‘globally’ indeterminate: they do not claim that the class of legal reasons fails to justify a unique outcome in all cases; rather it fails to do so ‘locally’, i. e., in a particular range of cases such as cases that reach the stage of appellate review.” Ibid at 41 [emphasis in original].

18. Nor, as Susan Haack has demonstrated, can the development of new logics beyond the “classical logic” of propositional calculus and quantification theory, such as modal logics, deontic logics, and relevance logics, rescue the identification of rationality with logicality.

Non-formal reason is not just about improving the rationality of our judgment but also improving the rationality of our rationality.
30. The notion of reason as a regulatory ideal for judging is right, but the rule-application model of formal reason cannot serve that function because it is a degenerate idealization. In science an idealization is a model that is helpful because it simplifies a part of the real world by ignoring inessential information. Removing the effect of friction from the model of an inclined plane in physics, e. g., is a useful, simple, non-degenerate idealization for measuring acceleration down a plane. Doing so does not affect the fundamental underlying physical structure, so if necessary, the independent factor of friction can be restored to the model. With a degenerate idealization, removing a factor changes the underlying fundamental structure so that factor cannot be reinserted. Given its extensive simplification, formal reason is a degenerate idealization of rationality, and the rule-application of formal reason is, in turn, a degenerate idealization of judging. It can be pragmatically useful to treat a degenerate idealization as a simple idealization, but the history of theoretical accounts of judicial decision making manifestly demonstrates that that is not the case for the model of deriving uniquely correct decisions from rules. For discussions of these ideals and idealizations in science, see C A Hooker, Reason, Regulation, and Realism (State University of New York Press, 1995) at 52-53, 58-59, 307-08, 313-14, 318-26, and 350.

35. See Frank, supra note 29, because, as Brown and Hooker explain, non-formal reason is needed to vindicate the rationality of science.

45. Kennedy is supposing that he is a judge in a trial court, not an appellate court. An enticing response to legal realism is to mitigate its damage to judging by confining indeterminacy, if not exclusively at least predominantly, to appellate courts. See Leiter’s discussion of legal realism (supra note 7 at 73-79) and Schauer’s discussion of Llewellyn (supra note 22 at 137-38). That proposal restricts indeterminacy to rule bewitchment, in particular, conflicts between and among rules. It ignores the fact skepticism of legal realism: the rampant indeterminacy in ascertaining the relevance of facts as well as rules. Appreciating fact skepticism would, it seems, suggest that there is more, not less, indeterminacy in trial courts because trial judges have to wrestle with both facts and rules. That is a mistake, however, because the relevance of facts and rules is not established singly, but jointly. Determining the relevance of facts or rules is a complex symbiotic process in which facts and rules interact dynamically, reciprocally, and reflexively. Kennedy nicely captures that process.
