4. JVeue Grundlagen der Logik, Arithmetic und Mengenlehre ; 

 von Julius Konig. Pp. viii, 259. Leipzig, 1914 (Veit & Co.). 

 — The chief work of the scientific life of Julius Konig was the 

 study of logic and in particular of that highly developed and 

 specialized logic which is necessary for modern mathematical in- 

 vestigations in the theory of sets (Mengenlehre). When he died 

 he left practically complete a book which presented his views and 

 researches and which his son has now seen through the press. 

 The author may fairly be said to hold a mean position between 

 the clean-cut mathematical theorists like Peano, Frege, and 

 Russell, and the psychological investigators like Wundt. His 

 work therefore was not easy and appealing to either mathematician 

 or psychologist. He was a transcendentalist in that he placed 

 confidence in Zermelo's principle of selection (Auswahlsprinzip), 

 which Poincare and other intuitionalists rejected. The style of 

 the book is such that properly to digest the text would require 

 almost as much work as to write it. e. b. w.
