it, yet he would readily understand its nature 

 and purport; and if the problem involved in that 

 question were explained to him, he would have no 

 difficulty in comprehending it. But not so with 

 the science of health and disease, or rather that 

 which teaches the nature of health and disease : and 

 the reason clearly is, because he knows nothing 

 whatever of the fundamental laws upon which life 

 depends nothing whatever of the several actions 

 which constitute life nothing whatever of the inti- 

 mate structure of the living organs. He knows 

 neither how he lives, nor how he moves, nor how 

 he breathes neither the " how " nor the " why" 

 The very language of the science is a dead letter to 

 him ; being borrowed, I verily believe, from every 

 tongue that was ever spoken, and, for aught I know, 

 from some that were never spoken at all. It is 

 true, he has some notion of the general appearance 

 of a few of the larger organs, because he has seen 

 similar organs in dead animals. For instance, he 

 has seen a great reddish mass of flesh, and has heard 

 it called a liver; and he has been told, that in 

 the liver the bile is made ; but beyond this vague 

 and meagre notion he knows literally nothing. As
