this is because he honors the people who died in the war and he inspires others to look back at the morals the country started with (liberty and all men would be created equal) and he does this to remind the people of who they are and who they should be.

President Abraham Lincoln's speech at Gettysburg is one that addresses the need for those listeners and the common mass to honor the sacrifices the soldiers made. They died while fighting for their country and their rights, defending the others even at the cost of their own lives.
Based on the two excerpts, it is evident that Lincoln uses the image of the fathers building the nation on the basis of equality and liberty for all. And it is upon them to see whether that nation made can stay united for long. In an effort to inspire the people, he emphasized on the need to honor the dead and the sacrifices of others. The actions of "<em>the brave men</em>" will never be forgotten what they did. And it is this that the people need to know and remember when they think of how the great nation of America came to be. It is a form of reminder for them about who they are and how they came to be.
