Final answer:
Direct expression, including direct quotes, is valuable for adding specificity and credibility to writing, while indirect expression, like paraphrasing, is beneficial for simplifying complex ideas and subtly conveying judgments. The choice between the two depends on the context and desired impact of the communication.
Step-by-step explanation:
The uses or values of direct and indirect expression are essential in communication, writing, and analysis. Direct expression, such as a direct quote, offers concrete evidence that enhances credibility and specificity in writing. They are powerful because they can establish ethos and provide solid backing to one's argument, often using the original author's distinctive wording to add weight to a point.
On the other hand, indirect expression involves paraphrasing or summarizing the original material, which can simplify complex ideas and highlight the most significant points without the density of the original text. Indirect expressions are useful for connecting descriptive claims with evaluative claims, subtly conveying a stance or judgment. For instance, in saying 'This knife is too dull to cut anything,' one indirectly evaluates the knife's quality in relation to its purpose.
When choosing between direct and indirect expressions, it is critical to consider the context. For expressive purposes, direct expressions such as exclamations ('holy cow!', 'ouch', 'hooray!') can strongly convey the speaker's emotions. In writing, direct quotations serve best when the exact wording is particularly powerful or apt, while indirect expressions allow writers to assert their interpretation and better integrate sources into their analysis or narrative.
