| 30 "Friends, Romans, countrymen, lend me your ears! \ |
| 31 I come to bury Caesar, not to praise him. \ |
| 32 The evil that men do lives after them, \ |
| 33 The good is oft interred with their bones; \ |
| 34 So let it be with Caesar. The noble Brutus \ |
| 35 Hath told you Caesar was ambitious; \ |
| 36 If it were so, it was a grievous fault, \ |
| 37 And grievously hath Caesar answer'd it. \ |
| 38 Here, under leave of Brutus and the rest- \ |
| 39 For Brutus is an honorable man; \ |
| 40 So are they all, all honorable men- \ |
| 41 Come I to speak in Caesar's funeral. \ |
| 42 He was my friend, faithful and just to me; \ |
| 43 But Brutus says he was ambitious, \ |
| 44 And Brutus is an honorable man. \ |
| 45 He hath brought many captives home to Rome, \ |
| 46 Whose ransoms did the general coffers fill. \ |
| 47 Did this in Caesar seem ambitious? \ |
| 48 When that the poor have cried, Caesar hath wept; \ |
| 49 Ambition should be made of sterner stuff: \ |
| 50 Yet Brutus says he was ambitious, \ |
| 51 And Brutus is an honorable man. \ |
| 52 You all did see that on the Lupercal \ |
| 53 I thrice presented him a kingly crown, \ |
| 54 Which he did thrice refuse. Was this ambition? \ |
| 55 Yet Brutus says he was ambitious, \ |
| 56 And sure he is an honorable man. \ |
| 57 I speak not to disprove what Brutus spoke, \ |
| 58 But here I am to speak what I do know. \ |
| 59 You all did love him once, not without cause; \ |
| 60 What cause withholds you then to mourn for him? \ |
| 61 O judgement, thou art fled to brutish beasts, \ |
| 62 And men have lost their reason. Bear with me; \ |
| 63 My heart is in the coffin there with Caesar, \ |
| 64 And I must pause till it come back to me."; |
