 Despite the long history of casuistry, there is little that can usefully be said about how one ought to reason about competing analogies. In the law, where previous cases have precedential importance, more can be said. As Sunstein notes (Sunstein 1996, chap. 3), the law deals with particular cases, which are always “potentially distinguishable” (72); yet the law also imposes “a requirement of practical consistency” (67). This combination of features makes reasoning by analogy particularly influential in the law, for one must decide whether a given case is more like one set of precedents or more like another. Since the law must proceed even within a pluralist society such as ours, Sunstein argues, we see that analogical reasoning can go forward on the basis of “incompletely theorized judgments” or of what Rawls calls an “overlapping consensus” (Rawls 1996). That is, although a robust use of analogous cases depends, as we have noted, on some shared background agreement, this agreement need not extend to all matters or all levels of individuals’ moral thinking. Accordingly, although in a pluralist society we may lack the kind of comprehensive normative agreement that made the high casuistry of Renaissance Christianity possible, the path of the law suggests that normatively forceful, case-based, analogical reasoning can still go on. A modern, competing approach to case-based or precedent-respecting reasoning has been developed by John F. Horty (2016). On Horty’s approach, which builds on the default logic developed in (Horty 2012), the body of precedent systematically shifts the weights of the reasons arising in a new case.
