When Lincoln says, “The world will little note, nor long remember what we say here, but it can never forget what they did here,” what is his purpose for using brevity? to avoid having to give additional details about why the world will not remember and why people should never forget
to show how he really does hope that his speech will become something everyone remembers
to use words with strong connotations that suggest heroism and forgetfulness
to convey that his speech is not as important as the actions of the people who fought for their country
