3^6 On Natural and Moral Pkilosojyln/. 



M true, it connects ab origine the theories of 

 body and mind, it'suggestsa common mode of 

 investigating the theories of both, and by one 

 and the same process establishes a sound and 

 true philosophy in both. It will not be -neces- 

 sary therefore, to dwell long on the object pre- 

 sented m the title of this essay. The connec-

 rect inference from the conclusion that I have 

 endeavoured to establish. If the ceconomy of 

 the natural and moral world be in the de- 

 si^nina: mind of the Creator conducted in one 

 common mode, there can be but one mode to 

 man of entering into the views of the Creator, 

 of investigating the nature, the characteristic 

 difference, the end> the fitness of every being 

 whom he has subjected to the view of man. 

 The rational world is atJength convinced that 

 in natural philosophy notruetheoryisto.be 

 derived from bold conjecture. To a*rrive at 

 truth, man must reason ; upwards, ahd not 

 downwards. He miistj begin with what he 

 does know, in order to discover what d priori 

 it' 13 rK)t possible that he should know ; he must 

 .retrace the steps of i the great artificer,:. by fol* 

 lowing him in his works. He must store up 

 facits ; 'compare,- digest them ;' separate tliose 

 which are conseciuent from those wl^ich are an- 

 tecedent, and,tj},us iaa regular grad^tiojira^ive
