What is an appeal to logic and reason called?

The correct choice is logos, which refers to an appeal to logic and reason in persuasive writing or speech. Logos is used to convince the audience through logical reasoning, facts, statistics, and rational arguments. By employing logos, a speaker or writer effectively engages the audience's intellect, leading them to conclusions based on logical progression.

The other options represent different rhetorical appeals. Ethos is about establishing credibility and ethical appeal. It focuses on the trustworthiness of the speaker or writer. Pathos appeals to the audience's emotions, aiming to elicit feelings that support the argument. Rhetoric encompasses the overall art of persuasion, which includes all these appeals but does not specifically denote an appeal to logic and reason. Understanding these distinctions helps clarify the pivotal role that logos plays in crafting convincing arguments.
