The commentary mentions ethical refinement and matters of religion and everyday life. Rhetoric is useful because a full demonstrative treatment may not be practicable for every audience or situation.
Example 1: encouraging parents to support consistent schooling.
Example 2: motivating a neighborhood to conserve water using accessible considerations.
Example 3: explaining the benefit of patient conduct during disagreements.
These applications focus on premises suited to an audience and useful guidance, not on pretending that such considerations equal a rigorous demonstration.
