THE PURPOSE AND SPIRIT OF THE 

 UNIVERSITY ' 



Modern students of human nature have 

 changed the old saying, ' ' Many men, many 

 minds," into the new dictum, "One man, 

 many selves. ' ' There is much talk of mul- 

 tiple personality. Our complex modern 

 life reflects itself in a composite person. 

 A man is said to have as many selves as 

 there are social groups of which he feels 

 himself a member. To maintain a busi- 

 ness self which can look a moral self 

 straight in the eye, to have a theological 

 self on good terms with a scientific self, 

 to keep the peace between a party self and 

 a patriotic self, to preserve in right rela- 

 tions a church self and a club self — such 

 are the present problems of many a man or 

 woman. One way to escape embarrassment 

 is to invite at a given time only congenial 

 and harmonious selves, and to banish from 

 the company the selves that are discordant 

 and disconcerting. The strong soul is he 

 who can summon all his selves into loyal 

 team play. Personality is the name men 

 give to this unity of the self, and purpose 

 is the organizing principle. Only as many 

 groups of thought and feeling are schooled 

 into cooperation by a well-eonsidered, 

 steadfast aim can a man be master of a 

 single self. To be sure, unity of a sort 

 can be achieved by one who has a meager 

 company of selves. Narrowness, provin- 

 cialism, bigotry, describe a personality in 

 which unity of purpose is won at a sacri- 

 fice of breadth, outlook and sympathy. 

 The highest type of personality grows out 

 of many far-reaching selves which have
