From “Lincoln 365,” by Arnold Kunst:
'Slavery is founded in the selfishness of man's nature -- opposition to it is in his love of justice. These principles are in eternal antagonism; and when brought into collision so fiercely, as slavery’s extension brings them, shocks, and throes, and convulsions must ceaselessly follow. Repeal the Missouri Compromise -- repeal all compromises -- repeal the Declaration of Independence -- repeal all past history, you still cannot repeal human nature. It still will be the abundance of man's heart that slavery's extension is wrong; and out of the abundance of his heart, his mouth will continue to speak.'
- Abraham Lincoln
'Every significant achievement in human history started out being impossible.'
