Final answer:
Pathos, ethos, and logos are terms that define methods of persuasion involving emotion, credibility, and logic, respectively. Ethos involves the authority of the speaker, pathos appeals to the audience's emotions, and logos relies on logical reasoning and evidence.
Step-by-step explanation:
Pathos, ethos, and logos are modes of persuasion used to convince audiences. They are also known as the three artistic proofs (Aristotle coined the terms) and are all represented in successful persuasive arguments.
Ethos is an appeal to the authority or credibility of the presenter. It is how well the presenter convinces the audience that he or she is qualified to speak on the particular matter. Evidence of ethos includes having expertise in the subject matter or having a respected title or reputation. For instance, in the given example of the pizza, the roommates claiming they have tried all other pizzerias in town to support their recommendation would be an appeal to ethos.
Pathos is an appeal to the audience's emotions. It can be achieved through storytelling, vivid imagery, or an emotional tone. The elements related to pathos in the pizza example are the appeal to the pleasure of eating good pizza and the desire to join others in enjoyment, as well as the adverse emotional consequences of letting the pizzeria go out of business.
Logos is an appeal to logic and reason. It often involves using data, facts, and evidence to support an argument. When we talk about the value for money and leftovers provided by Emiliano's pizza in the example, we are using logos to convince others through logical reasoning.
