Which term describes an appeal based on logic or reason?

The term that describes an appeal based on logic or reason is logos. In rhetoric, logos refers to the use of logical arguments, facts, statistics, and clear reasoning to persuade an audience. This appeal relies on a structured argument where the audience can follow the reasoning and find the conclusion sound based on evidence and logical progression.

Logos is vital in effective persuasion because it engages the audience's rational thinking, allowing them to make informed judgments based on the information presented. In contrast, the other terms focus on different aspects of persuasion: pathos appeals to emotions, ethos relates to credibility or ethical appeal, and mythos refers to a narrative or cultural storytelling approach. Understanding these distinctions helps to effectively formulate arguments and analyze persuasive techniques in various contexts.
