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.";
