The __ argument is discussed in this article. principal principle
The correct answer and explanation is:
The correct answer is: principle
Explanation (300 words):
In the sentence, “The __ argument is discussed in this article,” the correct word to use is principle, not principal.
Although principal and principle sound similar, they have different meanings and usages:
- Principle (noun): a fundamental truth, law, doctrine, or motivating force.
- Principal (noun/adjective): the most important or main; it can also refer to a person in a position of authority (like a school principal) or a sum of money in finance.
In the sentence provided, the context is discussing an argument—specifically, one that is likely based on an idea or rule. Therefore, “principle” fits best because it refers to a foundational concept or proposition that serves as the basis for reasoning or discussion.
Let’s break it down:
- “The principle argument” refers to an argument that is based on a principle—a foundational idea or belief.
- “The principal argument” would mean the main or most important argument. This might seem plausible, but the word “principle” is more accurate if the sentence refers to an argument centered on a guiding idea or rule.
Furthermore, the confusion is often highlighted in philosophical discussions through what is humorously known as the “Principal Principle”, a term coined by philosopher David Lewis. In that case, “principal” is used as an adjective meaning “most important,” and “principle” refers to a guiding rule. This helps demonstrate how both words might be used together but mean very different things.
To sum up: in the original sentence, the word needed is principle because the argument being discussed is likely grounded in a fundamental concept, not identified as the most important.
