Completing the Sentence: Selecting the Right Phrase

The question asks to fill in the blank in the sentence: "I shall consider, __________, the narrow lines of argument articulated by philosophers." This requires selecting the phrase that best modifies the verb "consider," indicating the manner or focus of consideration.

Analyzing the Options

Let's examine each option to see how it fits the context:

• 1. $sui generis$: This Latin phrase means "of its own kind" or unique. It doesn't fit grammatically or logically in this sentence. It describes something's uniqueness, rather than specifying focus.
• 2. $in particular$: This phrase means "specifically" or "especially." It fits perfectly, indicating that the consideration will focus specifically on the "narrow lines of argument articulated by philosophers."
• 3. $matter of fact$: This phrase means "actually" or "in reality." It implies stating a fact, which doesn't fit the context of how the arguments will be considered.
• 4. $serendipitously$: This adverb means "occurring or discovered by chance in a happy or beneficial way." Consideration of philosophical arguments is usually a deliberate act, not a chance occurrence.

Explanation of the Correct Choice

The phrase $in particular$ is the most suitable choice because it acts as an adverbial phrase specifying the focus. The sentence intends to convey that the speaker will pay special attention to the specific, narrow lines of argument put forth by philosophers. Using $in particular$ clarifies this focused consideration.

Therefore, the completed sentence reads: "I shall consider, in particular, the narrow lines of argument articulated by philosophers." This highlights that the consideration is not general but specifically targets the detailed arguments discussed.
