William O. Blake, The History of Slavery and the Slave Trade (1861)
“ Does slavery add anything to the common defense? Sir, the strength of a republic is in the arm of freedom. But, above all things, do the blessings of liberty consist in slavery? If there is any sincerity in our profession, that slavery is an ill, tolerated only from necessity, let us not, while we feel that ill, shun the cure, which consists only in an honest avowal that liberty and equal rights are the end and aim of all our institutions, and that to tolerate slavery beyond the narrowest limits prescribed for it by the constitution, is a perversion of them all. ”
