The motive of _Uncle Tom's Cabin_ was an appeal to the heart of the American people. There was no reference to political action, far less any suggestion of servile insurrection, and there was no discussion of methods of emancipation. The book set forth an organized, monstrous wrong, which it was in the power of the American nation, and above all, of the Southern people, to remove. The effect at the North was immeasurably to widen and deepen the conviction of the wrong of slavery, and the desire to remove it. But the way to practical action did not open; and strangely enough there was at first no visible effect on politics. The political logic of the situation led straight, as a first step, to the support of the Free Soil party. But though _Uncle Tom's Cabin_ appeared (as a book) in April, 1852, and its popularity was instant, the Presidential election seven months later showed a Free Soil vote less by 100,000 than four years before. The political effect of the book was to appear only when public events two years later gave a sudden spur to the hesitating North.
The South turned a deaf ear to the appeal. It shut the book out from its borders as far as it could, and one who inquired for it in a Southern bookstore would probably be offered _Aunt Phillis's Cabin_ or some other mild literary anti-toxin. The South protested that the book's picture of slavery was untrue and unjust. It was monstrous, so they said, that their labor system should be shown as having its natural result in the whipping to death of a saintly negro for his virtuous conduct. Another reply was: "If the book is true, it is really a eulogy of slavery, for it depicts slavery as producing in Uncle Tom a perfect character."
To the objections to the fidelity of her portraiture Mrs. Stowe replied with _A Key to Uncle Tom's Cabin_,--a formidable array of proved facts, as to the laws of the slave States, and specific incidents which paralleled or exceeded all she had told. As now judged, the novel has some serious imperfections as a picture of slavery. Probably the most important of these was expressed by Judge Tourgee, para-phrasing the proverb about the Russian and the Tartar: "Scratch one of Mrs. Stowe's negroes, and you will find a white man." She failed adequately to differentiate the two races, and described the negro too much from such specimens as Uncle Tom and George and Eliza Harris. She had never lived in the South, and her knowledge was obtained from observation in the border town of Cincinnati, from acquaintance with fugitives, and from the reports of Northern travelers--all interpreted with the insight of genius and the impulse of philanthropy. Her avowed purpose was not to make a literal or merely artistic picture, but to show the actual wrongs and legalized possibilities of wrong which called for redress. It did not lessen the justice of her plea, that the mass of negroes were more degraded than she knew, or that their average treatment was kinder than her portrayal showed.
