The following is an extract from Professor Hoffding's report to the Danish 

 Academy : 



" This extended and profound work commences with an inquiry into the rela- 

 tions subsisting between the individual and society. . . . Occasionally the author 

 makes contributions, as new as they are interesting, to the psychology of the child, 

 and proves himself the same skilful observer in finding identical or analogous 

 movements in different phases of conscious life. By the original, profound, and 

 penetrating use which he makes of the psychological and genetic method, he has 

 really cleared up the notions which must be used in the study of this question, and 

 thereby made much progress toward its solution. . . ." 



The Nation. " Professor Baldwin here puts forth the sequel to his remarkable 

 work on ' Mental Development in the Child and the Race.' . . . That it richly 

 deserves the gold medal of the Danish Academy there can be no doubt." 



Edinburgh Scotsman. " The most important contribution that has been made 

 to the science of psychology in recent years." 



The Spectator. "One of the latest and not least remarkable products of 

 American thought. It is a piece of close reasoning based upon vigilant observa- 

 tion. ... A vast amount of philosophic learning and of scientific research both 

 of a very rare kird - ^as gone to the making of this remarkable book." 



Professor Morselli, ii Rivista dl Filos, Sclent. "It is a vigorous book which 

 requires severe meditation and reveals in the author one who has profound knowl- 

 edge of psycho-social questions, and a thinker of the first rank. It constitutes a 

 most formal and severe refutation of individualism." 



Professor Richard T. Ely, in The Expositor. " What we have in this work is 

 a treatment of social psychology so profound, so original, and so striking in its re- 

 sults that it cannot fail to mark an epoch in the future both of sociological and of 

 psychological thought. . . . The child is examined in his mental development, 

 and the social results reached are as rich as they must be astonishing to one who 

 has hitherto failed to approach problems of society from this simple point of view. 

 One is reminded of Columbus and his egg; also the thought occurs that a little 

 child is still leading us into the truth. 



"The most impressive feature of Professor Baldwin's work to one thinking of 

 it as a whole is the new emphasis laid upon social forces. The philosophy of 

 the eighteenth century viewed external nature as the principal thing to be consid- 

 ered in a study of society, and not society itself. The great force in society was 

 extraneous to society. But according to the philosophy of our times, as it finds 

 expression in Professor Baldwin's work, the chief forces working in society are truly 

 social forces, that is to say, they are immanent in society itself. The importance of 

 this change can scarcely be overestimated. 



" Professor Baldwin's work is one which no student of society can afford to 

 neglect. It is one which will prove helpful to the teacher, and must profoundly in- 

 fluence the preacher who grasps its import. It gives us a social philosophy which 

 makes possible a rational and helpful discussion of the problems of the day. Pro- 

 fessor Baldwin has already accomplished great things, and from him sail greater 

 things may be expected in the future."
