62 EVOLUTION OF LIFE. 



cation of the appetite is the object to which all 

 their actions tend, and the motive by which 

 they are impelled ; by sense without reason, by 

 blind impulse, by fatal necessity, by brutal 

 instinct ; the final cause of which seems to be, 

 the gratification of the appetite as the MEANS, 

 and tJie propagation of the species as the END. 



With the human species, it is far otherwise. 

 The inferiority of the organs of sense, in man, 

 with relation to those belonging to animals, in- 

 general, and the lower order in particular ; as 

 well as the inferiorty of his faculties of strength 

 and of motion, of sensation, and of propaga- 

 tion, evidently prove, that a mere animal ex- 

 istence is not his true destination. If the end 

 of human existence depended on the extent and 

 perfection of living power, man would, in that 

 case, not only be inferior to the brute, but 

 the brute itself would be inferior to the vege- 

 table species : if it depended on the extent 

 and perfection of the organs of sense, the 

 condition of the brute would be far supe- 

 rior to the condition of man, since the or- 

 gans of sense in the one, are far more per- 

 fect than they are found to exist in the other. 

 What man is there whose digestive organs are 

 equal, in power, to those of animals in general ? 

 I have seen the stomach of a cod contain a 

 large haddock, the haddock to .have within 

 its stomach a whiting, and the whiting a smelt.
