vi PREFACE 



this book is dedicated, was the first to establish the 

 general principles of an antimetaphysical science. 



I have added at the end of each chapter a list of 

 the chief papers of which I have made use. Although 

 far from complete, this may serve the beginner as a 

 guide for the further study of the subjects touched 

 upon. 



The book appeared first in German and was trans- 

 lated by Anne Leonard Loeb. As a number of new 

 facts have been found since the German edition ap- 

 peared, and as it seemed desirable to formulate my 

 antimetaphysical standpoint more precisely, I have 

 made extensive alterations. 



My thanks are due to a number of friends who 

 have offered suggestions, most of all to my pupil, 

 Miss Anne Moore.
