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. 



XL 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.* 



* Of 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 Iledico-Chirur- 

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