FIRST PRINCIPLES; 



IN TWO PARTS: 



L THE UNKNOWABLE. II. LAWS OF THE KNOW ABLE. 



In one Volume. 518 pages* 



&quot;Mr. Spencer lias earned an eminent and commanding position as a metaphysician, 

 tu \ his ability, earnestness, and profundity, are in none of his former volumes so con- 

 SI&amp;gt;,CTIOUS as in this. There is not a crude thought, a flippant fling, or an irreverent in 

 sinuation in this book, notwithstanding that it has something of the character of a 

 during and determined raid upon the old philosophies.&quot; Chicago Journal. 



&quot;This volume, treating of First Principles, like all Mr. Spencer s writings that have 

 fallen under our observation, is distinguished for clearness, earnestness, candor, and 

 that originality and fearlessness which ever mark the true philosophical spirit. His 

 treatment of theological opinions is reverent and respectful, and his suggestions and 

 arguments are such as to deserve, as they will compel, the earnest attention of all 

 thoughtful students of first truths. Agreeing with Hamilton and Mansel in the gene 

 ral, on the unknowableness of the unconditioned, he nevertheless holds that their being 

 is in a form asserted by consciousness.&quot; Christian Advocate, 



u The literary world has seen but few such authors as Herbert Spencer. There have 

 been metaphysical writers in the same exalted sphere who before him have attempted 

 to reduce the laws of nature to a rational system. But in the highest realm of philo 

 sophical investigation he stands head and shoulders above his predecessors ; not perhaps 

 purely by force of superior intellect, but partly owing to the greater aid which the 

 light of modern science has afforded him in the prosecution of his difficult task.&quot; 

 Boston Bulletin. 



&quot; Mr. Spencer is achieving an enviable distinction by his contributions to the coun 

 try s literature ; his system of philosophy is destined to become a work of no small 

 renown. Its appearance at this time is an evidence that our people are not all absorbed 

 tn war and its tragic events.&quot; Ohio State Journal. 



&quot; Mr. Spencer s works will undoubtedly receive in this country the attention they 

 merit. There is a broad liberality of tone throughout which will recommend them to 

 thinking, inquiring Americans. &quot;Whether, as is asserted, he has established a new sys 

 tem of philosophy, and if so, whether that system is better than all other systems, is 

 yet to be decided; but that his bold and vigorous thought will add something valuable 

 nd permanent to human knowledge is undeniable.&quot; Uttca Herald. 



&quot;Herbert Spencer is the foremost among living thinkers. If less erudite thas 

 Hamilton, he is quite as original, and is more comprehensive and catholic than Mail- 

 eel.&quot; Universalist.
