More generally, rhetorical phrasing can:

• make writing more engaging,
• make ideas more memorable,
• create emphasis,
• help readers follow the flow of an argument,
• evoke emotion or vivid imagery.

For example:

"Life moves forward."

is shorter, more vivid, and easier to remember than:

"Current political arrangements may deserve greater normative weight than ancient occupancy under certain theories of political legitimacy."

The first sentence is rhetorically powerful; the second is analytically precise. In academic writing, rhetorical language may enhance presentation, but it does not replace the need for explicit reasoning and supporting evidence.
