DEMONSTRATION, AND NECESSARY TRUTHS. 293 



We have now proceeded as far in the theory of Deduction 

 as we can advance in the present stage of our inquiry. Any 

 further insight into the subject requires that the foundation 

 shall have heen laid of the philosophic theory of Induction 

 itself; in which theory that of deduction, as a mode of 

 induction, which we have now shown it to be, will assume 

 spontaneously the place which belongs to it, and will receive 

 its share of whatever light may be thrown upon the great 

 intellectual operation of which it forms so important a part.
