Galenus saw a fool hanging on with his hands to the collar of a learned man and insulting him, whereon he said: `If he were learned he would not have come to this pass with an ignorant man.?

 Two wise men do not contend and quarrel 
 Nor does a scholar fight with a contemptible fellow. 
 If an ignorant man in his rudeness speaks harshly 
 An intelligent man tenderly reconciles his heart. 
 Two pious men keep a hair between them untorn 
 And so does a mild with a headstrong man. 
 If however both sides are fools 
 If there be a chain they will snap it. 
 An ill-humoured man insulted someone. 
 He bore it and replied: `O man of happy issue, 
 I am worse than thou canst say that I am 
 Because I know thou art not aware of my faults as I am.
