Explanation: The common theme that is shared by both speeches is <u><em>freedom for all</em></u>. What Abraham Lincoln's Gettysburg Address, and Martin Luther King's Jr. Nobel Prize acceptance speech share is the fight for freedom for all. Lincoln refers to the soldiers who have fought at Gettysburg and King refers to "humble children of God" who worked for freedom and equality for all.
"But if that is so," he said to himself, "and I am leaving this life with the consciousness that I have lost all that was given me and it is impossible to rectify it—what then?"
