These Essays constitute a body of massive and original thought upon a 

 large variety of important topics, and will be read with pleasure by all who 

 appreciate a bold and powerful treatment of fVmdamental themes. Tha 

 general thought which pervades this book is beyond doubt the most impor- 

 tant that the human mind has yet reached. — N. Y. Independent. 



Those who have read the work on Education, will remember the ana- 

 lytic tendency of the author's mind — his clear perception and admirable ex- 

 position of first principles — his wide grasp of facts — his lucid and vigorou« 

 •tyle, and the constant and controlling bearing of the discussion on practical 

 results. These traits characterize all Mr. Spencer's writings, and mark, io 

 •n eminent degree, the present volume. — N, Y. TVUmm, 



We regard the distinguishing feature of this work to be the peculiarly 

 Interesting character of its matter to the general reader. This is a great 

 literary as well as philosophic triumph. In the evolution of a system of 

 Philosophy which demands serious attention, and a keen exercise of the in- 

 tellect to fathom and appreciate, he has mingled much that is really popoUi 

 •od entertaining. — Rochester DeniocroL
