INTRODUCTION. 13 



assigned where their experience has taught them 

 that the limits of classes are inexact or variant a 

 fact which Universology not only points out but ac- 

 counts for, (as they are unable to do), if they would 

 be patient to study it ; but they have no patience for 

 such novelties. This first apparent discrepancy 

 with what they already know is enough for them, 

 and with, perhaps, five minutes examination of a 

 great new subject, and Method, in science, they de- 

 cide adversely ; and imagine they have investigated 

 it, and that their opinions should be the guide of 

 others who have not done so. 



17. The fact is, that, for the true appreciation, or, 

 with many, for any appreciation whatever, of Scien- 

 tific Analogy, a special training of a set of mental 

 faculties previously neglected is requisite, as much 

 so as when we would develop the Musical Ear, or the 

 Artistic Eye ; and the ordinary training of the Spe- 

 cialists in Science is adverse rather than favorable to 

 the ready acquisition of this new kind of knowledge. 

 This order of men, eminently respectable in their 

 own sphere, will have to be induced by various 

 means, some of them, perhaps, somewhat stringently 

 coerced, into a respectful deference for the subject to 

 be studied, When, however, they shall have ac- 

 quired the new point of view and the requisite new 

 habits of thought, and shall have become truly pos- 

 sessed of the facts and principles of the New Science, 

 their old and present habits of exactitude and pre- 

 cision will supervene, and will be invaluable as aids 

 to their own better understanding of the subject, and
