According to Aristotle the Ethos deals with the character of speaker and the speaker should appear credible during public speaking. He considered <em>competence, good intention and empathy</em> to be necessary for a speaker to appear credible. The ethos is transmitted through self portrayal, mostly through nonverbal and verbal factors, so a speaker should be aware of both verbal and nonverbal factors. He also said that there is no good or bad self portrayal as it depends on the context.
