5. The Grammar of Science ; by Karl Pearson, 2d ed. 

 revised and enlarged, pp. 1-548, figs. 1-33 (Adam and Charles 

 Black, London; Macmillan Company, New York), 1900. — This 

 book illustrates the undoubtedly strong trend of opinion among 

 leaders of scientific thought toward some form of idealism. The 

 inadequacy of the cruder forms of materialism to satisfy the 

 questioning of the thinking mind has led men to look inward to 

 the form of their conceptions of phenomena, in order to ascertain 

 the relation these phenomena bear to each other. 



The following passage expresses tersely the author's purpose : 

 "The object of the present work is to insist . . . that science is 

 in reality a classification and analysis of the contents of the mind ; 

 and the scientific method consists in drawing just comparisons 

 and inferences from the stored impresses of past sense-impres- 

 sions, and from the conceptions based upon them. Not till the 

 immediate sense-impression has reached the level of a conception, 

 or at least a perception, does it become material for science. In 

 truth, the field of science is much more consciousness than an 

 external world. In thus vindicating for science its mission as 

 interpreter of conceptions rather than as investigator of a 

 ' natural law ' ruling an ' external world of material,' I must 

 remind the reader that science still considers the whole contents 

 of the mind to be ultimately based on sense-impressions" (p. 52). 

 The volume is full of keen observations and suggestions. The 

 chief additions made in this edition are the chapters discussing 

 the biological conceptions of science. w.
