What are the similarities between northerners and southerners that Lincoln outlines in the speech?

In his speeches, Abraham Lincoln emphasized that both Northerners and Southerners share fundamental human qualities, such as a desire for freedom, family values, and a commitment to their respective ways of life. He highlighted that both regions are driven by a common purpose: the pursuit of happiness and prosperity. Additionally, Lincoln pointed out that both groups are part of the same nation, united by a shared history and collective aspirations, despite their differences. This commonality, he argued, should serve as a foundation for reconciliation and unity during the Civil War.
