PSYCHOLOGY AS A CAREERS 



Psychology is the science which deals with 

 the nature of human and animal behavior and 

 with the direction of its forces from the point 

 of view of mental life. 



There are as many words in the dictionary 

 with mental connotation as with physical. 

 There are as many mental phenomena subject 

 to scientific study as material phenomena. The 

 mental sciences may in the near future have as 

 many branches and embrace as large scope as 

 the material sciences. 



As out of the pure physical sciences have 

 come engineering, medicine, architecture, and 

 other forms of appUed material sciences, so in 

 the near futiu'e will come the applications of 

 ps3'chology to education, medicine, industry, 

 art, and all other varieties of human endeavor 

 in which .scientific knowledge of human or ani- 

 mal behavior can be made of practical value. 



The opportunities for a career in mental 

 science will, in the near future, be as numerous 

 as in the material sciences. 



No science is more intimately and practically 

 related to the conduct of human life than is 

 psychology. It is, indeed, concerned primarily 

 with those facts and principles of experience 

 and action upon which our understanding of 

 ourselves as conscious beings and our ability to 

 understand and sympathize with our fellows 

 depend. 



Pure Psychology 



As now taught in the best colleges and uni- 

 versities, psychology is presented in several 

 fairly differentiated courses. Ordinarily there 

 is one general introductory cour.se of one year 

 furnishing a general sui-vey of the subject from

 for a Career in Science. ' '
