The physician will not indulge in useless dialectics, 136 but if he 

 knows his art he will prefer to show it by deeds rather than 

 words. 137 Life is fleeting, art is long, 138 and a cure may depend 

 upon the moment. 139 Hence the physician must not restrict his 

 attention to rational inference but must resort to the rule of rote to- 

 gether with reason ; 14 ° he must therefore have a knowledge of prac- 

 tice as well as of theory. 141 The main object of medicine is to effect 

 a cure; 142 above all the physician should avoid making much ado and 

 accomplishing nothing. 143 The art of medicine is not, however, a 

 mere routine ; a good share of the ability of the physician is shown in 

 his capacity to judge correctly touching what has been written ; 144 for 

 science is constituted by observations drawn from every quarter and 

 brought into a unity. 145 An art or science attests its reality by what 

 it accomplishes. 146 The art of medicine cannot always arrive at 

 absolute certainty ; but far from disputing the reality of medicine as 

 an art or science because it does not attain strict accuracy in all things, 

 one ought to praise it because of its desire to approximate it and to 

 admire it because from extreme ignorance it has proceeded to great 

 discoveries well and rightly made, and not by chance. 147

 This and several other matters incline me to the opinion that II. r^x^s belongs to 

 the fcurth century, though its general value for our purposes is not thereby appreci- 

 ably affected.
