What quality is based on the speaker's natural honesty, sincerity, and commitment to what is good and right?

The quality that is based on the speaker's natural honesty, sincerity, and commitment to what is good and right is known as Ethical Appeal. This concept, often referred to as ethos in rhetorical studies, emphasizes the credibility and ethical character of the speaker. When a speaker demonstrates genuine integrity and a strong moral foundation, they are likely to gain the trust and respect of their audience, which enhances their persuasive power.

An Ethical Appeal creates a connection between the speaker and the audience, fostering a relationship that encourages listeners to be more receptive to the message being conveyed. This form of appeal is essential in ethical communication as it assures the audience that the speaker is not just trying to persuade them for personal gain but genuinely cares about the truth and the well-being of others.

The other types of appeals, while important in their own right, do not focus specifically on the speaker's character. Emotional Appeal revolves around evoking feelings to persuade, while Logical Appeal focuses on reasoning and evidence. Practical Appeal relates to the tangible benefits or feasibility of an idea. None of these directly assess the speaker's integrity and ethical stance, which is central to Ethical Appeal.
