Final answer:
Abraham Lincoln aimed to include and heal the nation by promoting diversity and unity as well as fostering collaboration and reconciliation, particularly through his policies related to emancipation and reconstruction.
Step-by-step explanation:
Including and healing, according to President Abraham Lincoln, involved promoting diversity and unity, as well as fostering collaboration and reconciliation. During his presidency, Lincoln faced the challenging task of balancing the political and military goals of the Union with the process of emancipation and reconstruction. He initially proposed gradual compensated emancipation and sought to reconnect the rebelling states to the Union through policies that recognized the transition from a slave labor system to a free labor system. However, his approach didn't always receive strong support from Congressional Republicans, who sought more direct control over reunification. Nevertheless, Lincoln's intent was clear; he wanted to avoid revenge and conflict in the aftermath of the Civil War and instead aimed to heal the nation's wounds and promote unity.
