268 Objective Treatment of Logic. [CHAP. XL 



I for this omission of all reference to the subjective side of 

 I inference so long as we are dealing with Inductive Logic. 

 The inductive discoverer is of course in a very different 

 position. If he is worthy of the name his mind at every 

 moment will be teeming with notions which he would be as 

 far as any one from calling facts : he is busy making them 

 such to the best of his power. But the logician who follows 

 in his steps, and whose business it is to explain and justify 

 what his leader has discovered, is rather apt to overlook this 

 mental or uncertain stage. What he mostly deals in are the 

 complete inductions and well-grounded generalizations 

 and so forth, or the exploded errors which contradict them: 

 the prisoners and the corpses respectively, which the real 

 discoverer leaves on the field behind him whilst he presses 

 on to complete his victory. The whole method of science, 

 expository as contrasted with militant, is to emphasize the 

 distinction between fact and non-fact, and to treat of little 

 else but these two. In other words a treatise on Inductive 

 Logic can be written without any occasion being found to 

 define what is meant by a notion or concept, or even to employ 



such terms.

4. And yet, when we come to look more closely, signs 

 may be detected even within the field of Inductive Logic, 

 of an occasional breaking down of the sharp distinction in 

 question ; we may meet now and then with entities (to use 

 the widest term attainable) in reference to which it would 

 be hard to say that they are either facts or conceptions. 

 For instance, Inductive Logic has often occasion to make use 

 of ^Hypotheses : to which of the above two classes are these 

 to&quot; be referred ? They do not seem in strictness to belong to 

 either ; nor are they, as will presently be pointed out, by any 

 means a solitary instance of the kind. 



It is true that within the province of Inductive Logic
