M'Cosh {].)~continued. 



This volume is not put forth by its author as a special reply to Mr. 

 Mill's "Examination of Sir fVilliam Hamilton's Philosophy." 

 In that work Mr. Mill has furnished the means of thoroughly 

 estimating his themy of mind, of which he had only givtn hints 

 and glimpses in his logical treatise. It is this theory which Dr. 

 M'Cosh professes to examine in this volume; his aim is simply to 

 defend a portion of primary truth which has been assailed by an 

 ^ acute thinker who has extensive influence in England. ^^ In 

 such points as Mr. Mill's notions of intuitions and necessity, he 

 laill have the voice of mankind with ^zVw."— Athenaeum. "Such 

 a work greatly needed to be done, and the author was the man to 

 do it. This volume is important, not merely in reference to the 

 views of Mr. Mill, but of the whole school of writers, past and 

 present, British and Continental, he so ably represents." — Princeton 

 Review. 



THE LAWS OF DISCURSIVE THOUGHT: Being a Text- 

 book of Formal Logic. Crown 8vo. -^s. 



The main feature of this logical Treatise is to be found in the More 

 thorough investigation of the nature of the notion, in regard to 

 which the views of the school of Locke and Whately are regarded 

 by the author as very defective, and the views of the school of Kant 

 and Hamilton altogether erroneous. The author believes thai 

 errors spring far more frequently from obscure, inadequate, indis- 

 tinct, and confused Notions, and from not placing the Notions in 

 their p'oper relation in judgment, than from Ratiocination. In 

 this treatise, therefore, the Notion (with the term, and the Relation 

 of Thought to Language) will be found to occupy a larger relative 

 place than in any logical work written since the time of the famous 

 Art of Thinking. "The amount of summarized information 

 which it contains is very great; and it is the only work on the very 

 important subject with which it deals. Never was such u work 

 so much needed as in the present day." — London Quarterly 

 Review.
