"Not in any common lust for power did this uncommon tragedy have its origin. It is the rape of a virgin Territory,
compelling it to the hateful embrace of slavery; and it may be clearly traced to a depraved desire for a new
Slave State, hideous offspring of such a crime, in the hope of adding to the power of slavery in the National
Government.” …“The senator from South Carolina has read many books of chivalry, and believes himself a
chivalrous knight with sentiments of honor and courage. Of course he has chosen a mistress to whom he has
made his vows, and who, though ugly to others, is always lovely to him; though polluted in the sight of the
world, is chaste in his sight -- I mean the harlot, slavery. For her his tongue is always profuse in words. Let her
be impeached in character, or any proposition made to shut her out from the extension of her wantonness, and
no extravagance of manner or hardihood of assertion is then too great for this senator."
Sumner Butler Brooks
