Answer:
In the Gettysburg Address, Abraham Lincoln subtly addressed his audience's possible rejection of his ideas. He does this through the rhetorical device of pathos.
Explanation:
In spite of the great war being fought between the North and the South, and the huge emphasis on the issue of slavery, there were still those, even in the North, who found nothing wrong with owning slaves. Lincoln addresses this right away with his statement that "all men are created equal." This was an appeal to human emotion, or pathos, specifically to one's love for his fellow men. His reference to the creation of man here also alludes to the Creator God, Who, in fact, DID create all men equally. It is likely that most, if not all, of those present on the field that day at least claimed some form of belief in God. Given this, how could they argue with the Biblical fact that God created all men equally, which is so clearly in opposition to slavery?
