Abstract

The purpose of this paper is to examine a new work on legal reasoning by two American jurists whose aim is to ‘demystify’ it. The paper will not dispute the authors' central thesis that the existence of special forms of reasoning in law is false, but it will argue that a social science epistemologist would find their analysis at best inadequate. It will be argued that legal reasoning is not just reasoning from and about rules; it is also reasoning about facts and about the construction of factual situations. Consequently, it is vital for anyone wishing to have a serious understanding of how lawyers reason to have a familiarity with how social scientists, and indeed natural scientists, reason about fact. Such reasoning certainly involves induction, deduction and analogy but these methods are by no means adequate as an epistemological framework; schemes of intelligibility and paradigm orientations are equally important. If there is one paradigm orientation that is special to certain disciplines like theology and law, it is the authority paradigm, an orientation that must be distinguished from an inquiry paradigm. The problem with works by legal philosophers on legal reasoning is, it will be implied, that they are often conducted from within the authority paradigm and that this, in the end, prevents any demystification.

20 Interestingly Twining and Miers advocate an approach from the position of an advocate rather than a judge: Twining and Miers, above n 7, pp 333–340. This makes much sense when approaching legal reasoning in terms of argumentation but it does not have the same formal ‘authority’ as an assertion by a judge.

21 The same criticism cannot be made with such force against Twining and Miers, ibid, because although they are committed to the rule model their book draws much from American Realism and thus is more committed to the importance of facts: see in particular Twining and Miers, ibid, pp 182–183.

91 Professor Berthelot has summarised them in the following way: ‘the causal scheme (if x, then y or y = f (x)); the functional scheme (S→X→S, where one phenomenon X is analysed from the position of its function – X→S – in a given system); the structural scheme (where X results from a system founded, like language, on disjunctive rules, A or not A); the hermeneutical scheme (where X is the symptom, the expression of an underlying signification to be discovered through interpretation); the actional scheme (where X is the outcome, within a given space, of intentional actions); finally, the dialectical scheme (where X is the necessary outcome of the development of internal contradictions within a system)’: ‘Programmes, paradigmes, disciplines: pluralité et unité des sciences sociales’ in Berthelot, above n 9, p 484 (translation G Samuel).

101 In fact, Wilhelm Dilthey asserted that the difference between the natural sciences and social sciences was that the former privileged a causal scheme of intelligibility while the latter, which he described as Geiteswissenschaften, should privilege the hermeneutical scheme since the work of social scientists was one of interpretation of social fact.

186 See, eg, Lord Donaldson in X Ltd v Morgan-Grampian plc [1990] 2 WLR 421 at 432: ‘Lord Hailsham once said that “the rule of law is a confidence trick”. What he meant was that the rule of law depends upon public confidence and public acceptance of the system whereby Parliament makes the laws, the courts enforce them and the vast majority of citizens accept them until they can get them changed’.

187 See generally, eg, MacCormick, above n 47.

188 See, eg, the statement by Alexander and Sherwin, above n 1, p 17: ‘For in a community of rule-sensitive particularists, everyone would realize that no one was treating rules as serious rules. Therefore, the settlement value of rules would be reduced, which in turn would mean less expected compliances with rules and therefore less settlement value, and so on until the rules collapsed completely as serious rules’. This may or may not be true, but the authors feel under no obligation to offer the reader any empirical evidence as to the validity of this prediction. Consequently is their assertion that different from the assertion by one William Miller (1782–1849) who applied scientific and mathematical methods to the Book of Revelation and concluded that the Second Coming of Christ would occur in the year of 1843? On this Miller assertion see Armstrong, K The Battle for God: Fundamentalism in Judaism, Christianity and Islam (Harper Perennial, 2004) pp 9091.Google Scholar Armstrong observes that the failure of Christ to return did not mean the end of millenialism: ‘other sects... adjusted the eschatological timetable, and, by eschewing precise predictions, enabled new generations of Americans to look forward to an imminent End of history’ (p 91). Perhaps Miller should have become a legal theorist.
