FALLACIES: ' 



A View of Logic from tlie Practical Side. 



By ALFBED SIDGWICK, B. A., Oxon. 

 12mo. Cloth, $1.75. 



This book is intended mainly for the general reader. That is to say, 

 it requires no previous technical training, and is written as much as pos- 

 sible from the unprofessional point of view. 



" A book intended for popular use, and one now very much needed in these days 

 of half education, when so many persons are the prey of illusions. It treats mainly 

 of the methods of proof, shows what evidence is, and the different sorts needed to 

 produce belief, and what are the fallacies most suited to deceive." — Hartford Cmirant. 



"Like all the others in this series, this volume is intended for the general reader, 

 but the trained logician will find it useful and suggestive." — New York Herald. 



"An important treatise on a topic that deserves the attention of all thinking people. 

 ITie author writes mainly for the general reader; no previous technical training, but 

 only a fair degree of intelligence and application, is needful to follow the train of his 

 thought." — Cultivator and Country Gentleman. 



" Even among educated men logic is apt to be regarded as a dry study, and to be 

 neglected in favor of rhetoric ; it is easier to deal with tropes, metaphors, and words, 

 than with ideas and arguments— to talk than to reason. Logic is a study; it re- 

 quires time and attention, but it can be made interesting, even to general readers, as 

 this work by Mr. Sidgwick upon that part of it included in the name of 'Fallacies' 

 shows. Logic is a science, and in this volume we are taught the practical side of it. 

 The author discusses the meaning and aims, the subject-matter and process of proof, 

 unreal assertions, the burden of proof, non-sequiturs, guess-work, argument by exam- 

 ple and sign, the reductio ad absurdum, and other branches of his subject ably and 

 fully, and has given us a work of real value. It is furnished with a valuable appendix, 

 and a good index, and we should be glad to see it in the hands of thinking men who 

 wish to understand how to reason out the truth, or to detect the fallacy of an argu- 

 ment" — The Churchman. 



"Its perusal would save many a man from being misled." — Louisville {Ky.) Chris- 

 tian Observer. 



"The author has bestoAved much labor upon the production, and the originality of 

 his ideas is refreshing. lie holds that to combat fallacy is the raison d'^etre of logic, 

 hence, instead of touching logic directly, he treats, in a systematic manner, of those 

 fallacies which logic combats." — Ilarrisburg {Pa.) Telegraph.
