"Every year seems to widen the influence of that philosophical inquirer, in whom, 

 long ago, J. 8. Mill recognized one of the most vigorous as well as boldest thinkers 

 that English speculation has produced. As the majestic outlines of his design have 

 been disclosed, there has been a growing willingness to recognize not only the breadth 

 and solidity of his conclusions, but their regulative bearing on human conduct and. the 

 practical concerns of life. It remained for the author to define the final outcome of 

 his philosophy, and this has been done in the present work."— New York Sun. 



"Mr. Spencer's main purpose is to ascertain and describe the objective qualities of 

 right conduct, the external signs of the highest virtue, and to show their coincidence 

 with the results of progressive evolution. This he has done in the course of the pro- 

 found and exhaustive analysis, of which he is so consummate a master, of vigorous 

 but singularly lucid reasonings, and of ample and impressive illustrations from every 

 department of Nature."— iVew York Tribune. 



" "We think that the verdict on this book of all candid readers will be that it accom- 

 plishes what it professses to accomplish— it finds for the principles of right and wrong 

 in conduct a scientific basis ; and, if this be true, it is needless to say that its effect will 

 be to give a new impulse and a new direction to ethical studies. 1 ' 1 — Popular Science 

 Monthly. 



"However widely many will differ with Mr. Spencer as to some of his generaliza- 

 tions, and especially as to his great underlying theory, all must admire and value the 

 clearness and fairness of his reasoning, his wonderful" mastery of faetE in all domains 

 of science, the keenness of his philosophic insight, and the singular beauty of his 

 ethical teachings. His impress upon the speculative thought of the age is undoubtedly 

 greater than that of any other living man." — Chicago Evening Journal. 



"As examples of lucid, elegant style, Mr. Spencer's writings deserve careful study; 

 but -beyond and above mere form he is deserving of higher praise. Lucid style ac- 

 companies a wonderfully trained brain, filled with almost all kinds of contemporary 

 knowledge, thoughts that reach, surround, and master the loftiest subjects, a love of 

 symmetry that connects masses of heterogeneous and conflicting thoughts into perfect 

 order and harmony, and an almost miraculous patience that is an attribute of genius 

 alone."— Boston Gazette. 



" This book is constructed upon a clear and symmetrical plan, and is a model of 

 lucid and terse treatment. Such are the author's richness and variety of knowledge 

 that he is able to illustrate at every step the abstract principles which he lays down by 

 concrete instances cited from Sociology or the physical sciences. In no chapter does 

 his grasp of the subject appear more firm than in that on the 'Evolution of Conduct. 1 "
