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.
