This philosophical system differs from all its predecessors in being 

 solidly based on the sciences of observation and induction; in repre- 

 senting the order and course of Nature ; in bringing Nature and man, 

 life, mind, and society, under one great law of action ; and in developing 

 a method of thought which may serve for practical guidance in dealing 

 with the affairs of life. 



"The only complete and systematic statement of the doctrine of 

 evolution with which I am acquainted is that contained in Mr. Herbert 

 Spencer's 'System of Philosophy,' a work which should be carefully 

 studied by all who desire to know whither scientific thought is tending." 

 T. H. HUXLEY. 



" Mr. Spencer is one of the most vigorous as well as boldest thinkers 

 that English speculation has yet produced." JOHN STUART MILL.
