Sometimes I wish eastern Congo would suffer an earthquake or a tsunami, so that it might finally get the attention it needs. The barbaric civil war being waged here is the most lethal conflict since World War II and has claimed at least 30 times as many lives as the Haiti earthquake.

Yet no humanitarian crisis generates so little attention per million corpses, or such a pathetic international response.

-Nicholas Kristof, NY Times Columnist writing in 2010

Allusion

• A reference to a well-known person, place, or thing.

• E.G. Nick Jans describing Chris McCandless:• “Such willful ignorance… amounts to disrespect for

the land, and paradoxically demonstrates the same sort of arrogance that resulted in the Exxon Valdez spill—just another case of underprepared, overconfident men bumbling around out there and screwing up because they lacked the requisite humility.”

Page 10: Persuasion. Appeals Logical Ethical Emotional Logical appeals (logos) Appeals to reason Use statistics Use cause and effect “The National Safety Council

Hyperbole

• The use of exaggeration for persuasive effect

supported, and emotionally moving.• Or…• His words were sparkling jewels; his sentences

were intricately carved; his paragraphs were solid as blocks of granite.

Antithesis

• Contrary ideas expressed in a balanced sentence.

• It can be a contrast of opposites: “Evil men fear authority; good men cherish it.”

• Or it can be a contrast of degree: “One small step for man; one giant leap for mankind.”

• Examples: almost, often, usually, maybe, most, frequently, many, frequently…

Concessions
