xx PREFACE TO THE FIRST EDITION. 



industrial government as passing through like phases with 

 political government. 



VOL. III. 



VII. LINGUAL PROGRESS. The evolution of Languages 

 regarded as a psychological process determined by social con- 

 ditions. 



VIII. INTELLECTUAL PROGRESS. Treated from the same 

 point of view: including the growth of classifications; the 

 evolution of science out of common knowledge; the advance 

 from qualitive to quantative prevision, from the indefinite 

 to the definite, and from the concrete to the abstract. 



IX. ^ESTHETIC PROGRESS. The Fine Arts similarly dealt 

 with: tracing their gradual differentiation from primitive in- 

 stitutions and from each other; their increasing varieties of 

 development; and their advance in reality of expression and 

 superiority of aim. 



X. MORAL PROGRESS. Exhibiting the genesis of the slow 

 emotional modifications which human nature undergoes in its 

 adaptation to the social state. 



XI. THE CONSENSUS. Treating of the necessary inter- 

 dependence of structures and of functions in each type of so- 

 ciety, and in the successive phases of social development.* 



*0f this treatise on Sociology a few small fragments may be found in 

 already-published essays. Some of the ideas to be developed in Part II 

 are indicated in an article on " The Social Organism," contained in the 

 last number of the Westminster Review ; those which Part V. will work 

 out, may be gathered from the first half of a paper written some years 

 since on " Manners and Fashion ; " of Part VIII. the germs are contained in 

 an article on the " Genesis of Science ; " two papers on " The Origin and 

 Function of Music " and " The Philosophy of Style," contain some ideas 

 to be embodied in Part IX. ; and from a criticism of Mr. Bain's work on 

 " The Emotions and the Will," in the last number of the Medico-Chirur- 

 gical Review, the central idea to be developed in Part X. may be inferred.
