In the scheme of nature Mind is ever associated -with Life. 

 The third division of this philosophical system will therefore bo 

 Psychology, or the Science of Mind. This great subject will bo 

 considered, not by the narrow methods usual with metaphy 

 sicians, but in its broadest aspects as a phase of nature s order 

 to be studied by observation and induction through the whole 

 range of psychical manifestation in animated beings. The sub 

 ject of mind will be regarded in the light of the great truths of 

 Biology previously established ; the connections of mind and life 

 will be traced ; the progress of mentality as exhibited in the ani 

 mal grades, and the evolution of the intellectual faculties in man 

 will be delineated and the cooperation of mind and nature in the 

 production of ideas and intelligence unfolded. We have no work 

 upon mind of this comprehensive and thoroughly scientific char 

 acter : the materials are abundant, and the necessity of their 

 organization is widely recognized. That Mr. Spencer is eminently 

 the man to perform this great task is proved by the fact that ho 

 is already the author of the most profound and able contribu 

 tion to the advancement of psychological science that has ap 

 peared for many years. 



In the true philosophic order, Biology and Psychology prepare 

 the way for the study of social science, and hence the fourth part 

 of Mr. Spencer s system will treat of Sociology, or the natural laws 

 of society. As a knowledge of individuals must precede an under 

 standing of their mutual relations, so an exposition of the laws of 

 life and mind, which constitute the science of human nature, must 

 precede the successful study of social phenomena. In this part 

 will be considered the development of society, or that intellectual 

 and moral progress which depends upon the growth of human 

 ideas and feelings in their necessary order. The evolution of 

 political, ecclesiastical, and industrial organizations will be 

 traced, and a statement made of those principles underlying all
