Aristotle's Credibility

Overall, I agree with Aristotle when he says that having a good moral character and establishing credibility is an important part of being successful in persuasive speaking. I believe that if someone is passionate and knowledgeable about the topic they are discussing they would be able to establish credibility with their audience. I also agree when Aristotle says that credibility needs to be earned during the speech. However, it would be challenging for a speaker who in the past has been known to not be a credible source for information to change the views of an audience who already has bad judgement of him or her. In vice versa a speaker who has been credible in the past would not have as hard of a time convincing an audience of his credibility.
