NOTES TO THE INTRODUCTION. 



A HISTORY OF THE INDUCTIVE SCIENCES. This title has 

 the fault of seeming to exclude from the rank of Inductive 

 Sciences those which are not included in the History ; as 

 Ethnology and Glossology, Political Economy, Psychology. 

 This exclusion I by no means wish to imply ; but I could 

 find no other way of compendiously describing my sub- 

 ject, which was intended to comprehend those Sciences in 

 which, by the observation of facts and the use of reason, 

 systems of doctrine have been established which are uni- 

 versally received as truths among thoughtful men ; and 

 which may therefore be studied as examples of the manner 

 in which truth is to be discovered. Perhaps a more exact 

 description of the work would have been, A History of the 

 principal Sciences hitherto established by Induction. I may 

 add that I do not include in the phrase " Inductive Sci- 

 ences," the branches of Pure Mathematics, (Geometry, 

 Arithmetic, Algebra, and the like,) because, as I have 

 elsewhere stated (Phil. Ind. Sc., B. n. c. 1), these are 

 not Inductive but Deductive Sciences : they do not infer 

 true theories from observed facts, and more general from 

 more limited laws : but they trace the conditions of all 

 theory, the properties of space and number; and deduce 

 results from ideas without the aid of experience. The 

 History of these Sciences is briefly given in Chapter 13 of 

 the Book just referred to.
