PREFACE TO PART IV* 



OF the chapters herewith published, constituting Part 

 I Y of The Principles of Sociology, seven have already seen 

 the light: not, however, all of them in England. For rea 

 sons which need not be specified, it happened that the chap 

 ter on Titles was not, like those preceding it, published in 

 the Fortnightly Review at the same time that it was pub 

 lished in periodicals in America, France, Germany, Italy, 

 Hungary, and Russia; and it is therefore new to English 

 readers. Five other chapters, namely Y, IX, X, XI, and 

 XII, have not hitherto appeared either at home or abroad. 



For deciding to issue by itself, this and each succeeding 

 division of Yol. II of the Principles of Sociology, I have 

 found several reasons. One is that each division, though 

 related to the rest, nevertheless forms a whole so far dis 

 tinct, that it may be fairly well understood without the rest. 

 Another is that large volumes (and Yol. II threatens to 

 exceed in bulk Yol. I) are alarming; and that many who 

 are deterred by their size from reading them, will not fear 

 to undertake separately the parts of which they are com 

 posed. A third and chief reason is that postponement of 

 issue until completion of the entire volume, necessitates an 

 undesirable delay in the issue of its earlier divisions: sub 

 stantially-independent works being thus kept in manuscript 

 much longer than need be. 



The contents of this Part are not, indeed, of such kind 

 as to make me anxious that publication of it as a whole 

 should be immediate. But the contents of the next Part, 



* The two parts of which this volume consists having been separately pub 

 lished, each with its preface, it seems most convenient here simply to repro 

 duce the two prefaces in place of a fresh one for the entire volume.
