"Lincoln shared many of the prevailing prejudices of his era. But, he insisted, there was a bedrock principle of equality that transcended race. The equal right to the fruits of one's labor. There are many grounds for condemning the institution of slavery. Moral, religious, political, economic. Lincoln referred to all of them at one time or another. But ultimately he saw slavery as a form of theft, of one person appropriating the labor of another. Using a black woman as an illustration, he explained the kind of equality in which he believed, 'In some respects she certainly is not my equal; but in her natural right to eat the bread she earns with her own hands without asking leave of any one else, she is my equal, and the equal of all others'. Shortly before the 1860 election, Frederick Douglass offered a succinct summary of the dilemma confronting opponents of slavery like Lincoln, who worked within the political system rather than outside it. Abstractly, Douglass wrote, most northerners would agree that slavery was wrong. The challenge was to find a way of 'translating antislavery sentiment into antislavery action'. The constitution barred interference with slavery in the states where it already existed. For Lincoln, as for most Republicans, antislavery action meant not attacking slavery where it was but working to prevent slavery's westward expansion. Lincoln, however, did talk about a future without slavery. The aim of the Republican Party, he insisted, was to put the institution on the road to 'ultimate extinction, a phrase he borrowed from Henry Clay. Ultimate extinction could take a long time. Lincoln once said that slavery might survive for another hundred years. But to the south, Lincoln seemed as dangerous as an abolitionist, because he was committed to the eventual end of slavery. This was why his election in 1860 led inexorably to secession and civil war."
