Final answer:
Lincoln's speeches reveal his nuanced position on slavery and equality, opposing the expansion of slavery while recognizing legal inequalities. By 1861, he upheld the permanent nature of the Union and opposed secession with a blend of firmness and conciliation in his speeches, effectively communicating his leadership goals.
Step-by-step explanation:
The speech from Abraham Lincoln on August 21, 1858, in Ottawa, Illinois, articulates his position on the issue of slavery and equality between Black and White people. He discussed the different types of equality, suggesting equality in legal rights but also acknowledging that there may not be complete equality in all aspects of life.
By March 1861, during his inaugural address, Lincoln's public position had evolved. He still maintained his stance against interference with slavery where it existed, but he strongly opposed the secession of the Southern states. Emphasizing the permanent nature of the Union, he was prepared to use force if necessary to uphold federal laws and prevent the dissolution of the Union.
