What term describes something that is appealing to the intellect and compelling?

The term "cogent" is used to describe arguments, reasoning, or ideas that are clear, logical, and convincing. When something is cogent, it effectively appeals to the intellect, as it presents information in a way that is easy to understand and persuasive. This characteristic is often crucial in fields such as law, philosophy, and debate where the ability to articulate a strong, compelling argument can significantly influence opinions and understanding.

In contrast, the other choices refer to different concepts. "Boorish" pertains to someone who is rude or insensitive, which does not convey appeal to the intellect. "Bourgeois" typically relates to the middle class or materialistic values, lacking the specific intellectual appeal implied in the question. "Canon" refers to a collection of works or rules recognized as authoritative, without necessarily indicating their intellectual engagement or compelling nature. Hence, "cogent" stands out as the most appropriate term to describe ideas that are intellectually appealing and compelling.
