HUMAN NATURE A SUBJECT OF SCIENCE. 431 



science of Human Nature may be said to exist, in proportion 

 as the approximate truths, which compose a practical know 

 ledge of mankind, can be exhibited as corollaries from the 

 universal laws of human nature on which they rest ; whereby 

 the proper limits of those approximate truths would be 

 shown, and we should be enabled to deduce others for 

 any new state of circumstances, in anticipation of specific 

 experience. 



The proposition now stated is the text on which the two, 

 succeeding chapters will furnish the comment.
