Outline of a Logical Analysis of Law

Extract

This study purports to demonstrate the possibility of applying logical analysis in the field of jurisprudence, and the usefulness of this method for exhibiting some essential features of the law.

logical analysis applies to language systems. To carry out the logical analysis of a language, is to construct a simplified model language “in close connection with” the given language, and to study the conditions of validity of the sentences of this model language. The given language is subjected to a kind of purifying chemical process. To deal with this simplified language seems to be a detour; it is, however, the most direct way to an ultimate insight into the logical structure of the given language.

16 One could, of course, take the expression 'is to be punished ...' in the sense of 'there are agencies charged with punishing. ..'. In this case, the latter sentence would also have declarative meaning, but it would not be a rule of law. As such, it can only be taken in the imperative sense.

17 For the distinction between syntactical, semantical and pragmatical (infra, p. 24) features, cfr. C. W. Morris, Foundations of the Theory of Signs (1938). Many valuable ideas of this book have been used in the present study.

18 Art. 1044 and 1046 of the New York Penal Code: “The killing of a human being is murder ..., when committed ... from a design to effect the death of the person killed or of another. ...”

19 A. C. Freeman, On Judgments, fifth edition (1925), p. 744.

20 Ibid., p. 747. The court argued in this case: “This judgment, even if it be erroneous, is not void; it ... can only be annulled or set aside by appeal or writ of error, taken for that very purpose. Courts have the inestimable privilege of rendering wrong decisions, and these decisions ... pass muster and pass current until (possibly and perhaps) reversed on error brought or appeal taken.” (Lacy v. Brandhorst (1900), 156 No. 457).

21 Unlike S1, S2 which states: ‘S1 is non-valid’, does not belong to A, since it speaks about a sentence of A. Cfr. infra, p. 34.

22 Like the definition of enforceability, this principle does not belong to A. Cfr. infra, p. 36.

23 Strictly speaking, this last sentence does not belong to B, but to a language which we might call C: it is a sentence about sentences about sentences of A. How many levels we need depends upon the field of law whose model language we intend to construct and to analyze.

24 Our distinction between levels is thus a purely logical one and has nothing to do with Kelsen's “Stufenbau.”

25 But as sentences of law they have no official quality and are therefore neither enforceable nor (legally) valid; they may only be correct and true.
