-  I come to bury Caesar, not to praise him.        
-  The evil that men do lives after them,           
-  The good is oft interred with their bones;       
-  So let it be with Caesar. The noble Brutus       
-  Hath told you Caesar was ambitious;              
-  If it were so, it was a grievous fault,          
-  And grievously hath Caesar answer'd it.          
-  Here, under leave of Brutus and the rest-        
-  For Brutus is an honorable man;                  
-  So are they all, all honorable men-              
-  Come I to speak in Caesar's funeral.             
-  He was my friend, faithful and just to me;       
-  But Brutus says he was ambitious,                
-  And Brutus is an honorable man.                  
-  He hath brought many captives home to Rome,      
-  Whose ransoms did the general coffers fill.      
-  Did this in Caesar seem ambitious?               
-  When that the poor have cried, Caesar hath wept; 
-  Ambition should be made of sterner stuff:        
-  Yet Brutus says he was ambitious,                
-  And Brutus is an honorable man.                  
-  You all did see that on the Lupercal             
-  I thrice presented him a kingly crown,           
-  Which he did thrice refuse. Was this ambition?   
-  Yet Brutus says he was ambitious,                
-  And sure he is an honorable man.                 
-  I speak not to disprove what Brutus spoke,       
-  But here I am to speak what I do know.           
-  You all did love him once, not without cause;    
-  What cause withholds you then to mourn for him?  
-  O judgement, thou art fled to brutish beasts,    
-  And men have lost their reason. Bear with me;    
-  My heart is in the coffin there with Caesar,     
-  And I must pause till it come back to me.""";
