A good grasp of rhetoric is also needed ethos: The speaker is perceived by the audience as credible (or not). •pathos: The speaker attempts to persuade the audience by making them feel certain emotions. •logos: The speaker attempts to persuade the audience by the use of arguments that they will perceive as logical.
