"Moreover, though he does not make the point explicitly, again the very fact that Douglass is ably disputing this argument on this occasion celebrating a select few's intellect and will (or moral character) — this fact constitutes a living counterexample to the narrowness of the pro-slavery definition of humans."
Frederick Douglass (1855). The Anti-Slavery Movement, A Lecture by Frederick Douglass before the Rochester Ladies' Anti-Slavery Society. ციტირების თარიღი: October 6, 2010. From page 33: "My point here is, first, the Constitution is, according to its reading, an anti-slavery document; and, secondly, to dissolve the Union, as a means to abolish slavery, is about as wise as it would be to burn up this city, in order to get the thieves out of it. But again, we hear the motto, 'no union with slave-holders;' and I answer it, as the noble champion of liberty, N. P. Rogers, answered it with a more sensible motto, namely—'No union with slave-holding.' I would unite with anybody to do right; and with nobody to do wrong."
