Final answer:
The implied premise in Lincoln's speech is that both Northerners and Southerners desire an end to the war's troubles, reflecting the overarching goal of peace despite divergent views on slavery. Emancipation became a strategic and moral aspect of the Union's war efforts.
Step-by-step explanation:
An example of a premise implied in Lincoln's speech is the idea that Northerners and Southerners both pray for the end of the war's troubles. This reflects the mutual desire for peace despite differing viewpoints on slavery and the direction of the nation. Lincoln himself acknowledged the divided state of the country in his speeches, emphasizing the principle that the United States could not endure as a nation half slave and half free, suggesting the inevitability of resolving these internal conflicts. Importantly, Lincoln's goal was to preserve the Union, and although he did not explicitly state an initial intent to end slavery at the outset of the war, the moral and political pressures, including those from abolitionists, led to its eventual inclusion in the Union's objectives through the Emancipation Proclamation.
Throughout the Civil War, Lincoln had to balance a range of political, military, and social considerations, leading to his decision to proceed with emancipation as a strategic war measure and a commitment to the broader moral imperative of ending slavery. Despite the difference in motivations among various groups in the North, the prevailing anti-slavery sentiment and the strategic advantages of emancipation played key roles in shaping Lincoln's policies and the outcome of the war.
