Seth bernstein empower software solutions inc. 64 REVIEWS HAO WANG and ROBERT MCNAUGHTON. Les systemes axiomatiques de la theorie des ensembles. With a preface by P.

Collection de logique math6matique, s6rie A. Gauthier-Villars, Paris; E. Nauwe- laerts, Louvain; 1953, 55 pp. This monograph contains in expanded form a lecture delivered by Hao Wang in Paris in 1951 and gives a survey of the numerous systems and subsystems of axiomatic set theory and of some of its recently obtained meta-properties. All this is discussed in twenty-three pages and the authors are unable to go into full detail on all topics. Nevertheless they succeed in presenting a clear picture of the development of axiomatic set theory and of recent research in this field.

The work will be useful to any one who is looking for some orientation in a wide field. Following is a summary of the content of the seven chapters. Cantor and the naive set theory. It is well known that the contradictions which were discovered around 1900 in set theory as created by Cantor led mathematicians and logicians to apply the axiomatic method to set theory. In 1908 two systems-namely Russell's theory of types and the Zermelo set theory - were published which succeeded in avoiding the known antinomies, and which are the origin of a series of related systems. They all try to provide a consistent basis for existing mathematics.

The theory of types, the underlying idea and intuitive model, the most important definitions and the set of axioms. In order to derive an extensive part of higher mathematics this system continues to admit impredicatively defined classes, and their presence prevents convincing oneself that type theory is consistent, although the known antinomies are not derivable in the naive way. The Zermelo set theory is expounded in the same manner, and its axioms are stated, both in ordinary rigorous terminology, and by means of the logistic notation with use of the symbolism of the restricted predicate calculus and axiom schemata. Fraenkel's Ersetzungsaxiom is given and a result, due to Rosser and Wang, concerning the relationship between the Zermelo and the Zer- melo-Fraenkel systems is stated. Some misprints are unfortunately left uncorrected.

The set theory of von Neumann and Bernays. In order to do without the axiom schemata used in the previous systems, Bernays considered sets and classes - where a class can be conceived of as the aggregate of all sets satisfying a given condition - and added a finite number of axioms which allow the construction of the class defined by any condition on sets that contains no bound class variables. It is sketched how the consistency of the Zermelo-Fraenkel system entails that of the Bernays version of set theory. Quine's systems of set theory. It is explained how the restrictions imposed by type theory were liberalized by means of Quine's use of the idea of stratification in his New foundations, and how the resulting system can be extended in a way very similar to the addition of classes discussed in the previous chapter. The extended system is relatively consistent to New foundations, but the proof is rather involved.

Some weaker systems of set theory. Number theory can be developed in a set theory without axiom of infinity (the so-called general theory of sets).

A description is given of a theory which has a finite number of types and takes as individuals the sets of the general theory of sets. The chapter ends with a discussion of the consequences and uses of Tarski's definition of truth. Chapter VII, on the relative strength of some of these systems, states results obtained by McNaughton, Mostowski, and Kemeny. The monograph closes with indexes and tables and a nine-page bibliography listing selected papers by sixty-six authors who have written about mathematical logic in a wide sense and about the new field called 'foundations of mathematics.'

REVIEWS 65 Described in the Preface as a 'final preliminary edition,' this is a text-book for undergraduates based on the authors' belief that 'some of the content and much of the spirit of modern mathematics' can be incorporated into courses for beginning students. Within the field of the JOURNAL are: Chapter I, Logic, which (with the aid of logistic notation) explains the truth-table method and some elementary laws of the propositional calculus and of quantifiers; Chapter V, containing an informal treatment of Boolean algebra and some of its applications; and parts of Chapter II, The number system, and Chapter VI, Functions. No claim is made to rigor in the way in which fundamental ideas of logic are introduced and applied - as indeed a fully rigorous treatment would hardly be possible, consistently with the authors' purpose. ALONZO CHURCH HUGO FISCHER. Zum Problem der UJbertragung mathetischer Prinzipien: Die 'All- gemeine Semantik.' Eine nichtaristotelische Wertungslehre Alfred Korzybskis.

Stu- dium generate, vol. 6 (1953), pp. This is primarily a popular descriptive account of Korzybski's 'general semantics.'

However, a number of other developments are described as having, or as if they had, some connection or points of contact with Korzybskianism. These include the semiotic of Carnap and Morris and the cybernetics of Wiener; also, more briefly, the semantics of Tarski, that of Chwistek, the work of the significists (besides Lady Welby, only Brouwer is mentioned by name), and a semiotic which is said to have been studied by 'K. Schr6der, Heisenberg, Schrbdinger.' ALONZO CHURCH PAUL F.

Was ist Logik? Zeitschrift fur philosophische Forschung, vol. 6 (1951-2), pp. The author criticizes various forms of psychologism and defends an 'ontological' view of logic.

This view includes the following theses: that truth and falsehood are properties of states of affairs (Sachverhalte), states of affairs being what 'that-clauses' ordinarily designate; that negation and conjunction are the same as diversity and togetherness, respectively, and are therefore Weltelemente; and that the 'most general' laws of being are the laws of logic. These theses were defended in a similar fashion in the author's XVII 276. CHISHOLM PAUL LORENZEN.

Die ontologische und die operative Auffassung der Logik. Actes du XIieme Congres International de Philosophie, Volume V, Logique, analyse philosophique, philosophic des mathumatiques, North-Holland Publishing Company, Amsterdam 1953, and Editions E. Nauwelaerts, Louvain 1953, pp. By the ontological conception of logic, the author understands the view, which he considers currently predominant, that the theorems of logic express universal truths independent of the symbolic operations involved in their proof. According to this view, the operations are significant only secondarily, namely as techniques for the establishment of those logical truths.

Lorenzen argues that this conception cannot answer the Kantian question as to how such ontological knowledge is possible at all; for the customary account of logical validity, which is formulated in a suitable meta- language, presupposes the validity of universal logical truths for the latter and thus leads into an infinite regress. The author then outlines what he terms the operational conception (operative Auffassung) of logic, which supposedly escapes this difficulty by developing the pro- cedure of operating according to logical rules 'out of itself' rather than by reference to a system of independent logical truths. The most fundamental part of logic thus conceived is protologic, which studies questions of derivability in regard to symbolic calculi.

A calculus is understood to be characterized by a finite set of basic rules which govern the 'derivation' of all its expressions, i.e., their construction out of elementary This content downloaded from 188.72.126.55 on Fri, 13 Jun 2014 04:01:38 AM All use subject to JSTOR Terms and Conditions Article Contents p. 65 Issue Table of Contents The Journal of Symbolic Logic, Vol.
