I feel like these concepts don't go well together in a single list. There's a big leap from "using logic" to using repetition, e.g., "of the people, by the people, for the people."

repeating something you want to emphasize seems like a logical choice to me, quite logical in fact.

The difference is whether you are appealing to the listener's logical faculties. Reasoning with someone feels somehow more respectful and authentic than pulling linguistic tricks to bypass their psychological barriers.
