That Walker's work is persuasive is clear from historical records. For written evidence shows that "The Appeal" provided a shot in the arm to the abolitionist movement, for according to Turner, it "crystallized the universal principles against slavery, and its influence was a crucial impetus to the antislavery crusade and its coherence and organization as a movement" (Walker 9). The nature of the theme advanced in the four-part "Appeal" -- enslavement and abolition -- should not to be considered the dominant factor in declaring "The Appeal" a literary classic, for indeed one can point to many other historical documents whose intent was to dismantle the slave state.
What makes Walker's work superior to other abolitionist writers is his ability to articulate his arguments against African enslavement in such a scholarly and literary manner that it moved people to take a position, and stimulated action. One can surmise that this quality moved the work beyond didacticism to the realm of proprogandist literature. Consequently, it is Walker's work alone that emerges as the mantra of the enslaved, so that it is he and not Harriet Beecher-Stowe, the white abolitionist, who authored Uncle Tom's Cabin that sets the agenda for change, with an awesome African-created deconstruction of the social, economic and political constitution of slavery. Were this not so why else would the enslaved risk their lives to read, or have "The Appeal" read to them? Why else would "The Appeal" inspire Nat Turner, a slave to revolution? Why else would the plantocracy offer rewards in the tens of thousands for Walker's capture - dead or alive? Clearly, the presentation of his themes resounded in a country in the throes of Civil War. Indeed, Walker's work had relevance in the vicious contumacious battle between Confederate and Union America.
Central to the Walker's writing is an uncanny ability to name, deconstruct, describe and define injustice.
