Final answer:
The purpose of Lincoln's speeches was to honor the lives lost in the Civil War, to reaffirm the nation's commitment to freedom and equality, and to promote reconciliation and unity post-war.
Step-by-step explanation:
The purpose of William Lloyd Garrison's speech was to achieve one of the outcomes listed. However, the question seems to contain a typo, confusing Garrison with Abraham Lincoln. Lincoln's speeches during the Civil War, such as the Gettysburg Address and his second inaugural address, were delivered to honor the lives lost in the Civil War, to reaffirm the nation's commitment to freedom and equality, and to promote reconciliation and unity in the post-war period.
Specifically, in his Gettysburg Address, Lincoln aimed to commemorate the soldiers' sacrifices and to redefine the war as a means to secure a 'new birth of freedom' and to ensure that the democracy 'shall not perish from the earth'. His later speeches continued to focus on the themes of reconciliation, healing the nation, and the rights of freed slaves.
