Preface xix 



most certainly not, must be the answer. And beyond a doubt 

 the raising of the question involves principles of organization 

 for scientific research that lift it high above mere personal 

 concern. 



No faith of mine is greater because none is rooted more 

 deeply in my scientific philosophy, than that in the ultimate 

 triumph of popular, that is of democratic principles in all 

 aspects of civilization. Indeed the facts — not the theories — 

 of organic unity and integration which have dominated all 

 my later work are the foundation of this faith. Whether 

 my particular hypotheses and theories of organismalism suc- 

 ceed or fail, there still are the raw data on which they rest. 

 These can not fail. If success does not crown my efforts in 

 handling the data it will crown those of others who shall 

 come after me. And when the principles for which I contend 

 shall have worked themselves more fully into the fabric of 

 civilization, the organizational, the administrative, and the 

 scientific policies aimed at in the Scripps Institution for Bio- 

 logical Research of the University of California will be 

 recognized as fundamentally sound. I will be specific here 

 to the extent of mentioning the policy of providing a special 

 business management for such institutions. 



Although my indebtedness to my professional co-workers 

 and official associates of the Zoological Department and the 

 Museum of Vertebrate Zoology at Berkeley, Professors C. A. 

 Kofoid, S. J. Holmes, and Dr. Joseph Grinnell, is indicated 

 by special references in the body of this book, I should be 

 sorry to have these references taken to indicate the full ex- 

 tent of my obligation to them, or to indicate that these are 

 the only members of those departments to whom I am in- 

 debted. 



It would be a source of keen regret to me, too, should my 

 single short reference to two of my biological associates on 

 the staff of the Scripps Institution, Mr. E. L. Michael and 

 Dr. C. O. Esterly, be taken as the full measure of what I
