One after another he took up and replied to the charges the South was making against the North at the moment:--Sectionalism, radicalism, giving undue prominence to the slave question, stirring up insurrection among slaves, refusing to allow constitutional rights, and to each he had an unimpassioned answer inpregnable with facts. The discourse was ended with what Lincoln felt to be a precise statement of the opinion of the question on both sides, and of the duty of the Republican party under the circumstances. This portion of his address is one of the finest early examples of that simple and convincing style in which most of his later public documents were written. "If slavery is right," he said, "all words, acts, laws, and constitutions against it are themselves wrong, and should be silenced and swept away. If it is right, we cannot justly object to its nationality--its universality; if it is wrong, they cannot justly insist upon its extension--its enlargement. All they ask we could readily grant, if we thought slavery right; all we ask they could as readily grant, if they thought it wrong. Their thinking it right and our thinking it wrong is the precise fact upon which depends the whole controversy. Thinking it right, as they do, they are not to blame for desiring its full recognition as being right; but thinking it wrong, as we do, can we yield to them? Can we cast our votes with their views, and against our own? In view of our moral, social, and political responsibilities, can we do this? "Wrong, as we think slavery is, we can yet afford to let it alone where it is, because that much is due to the necessity arising from its actual presence in the nation; but can we, while our votes will prevent it, allow it to spread into the national Territories, and to overrun us here in these free States? If our sense of duty forbids this, then let us stand by our duty fearlessly and effectively. Let us be diverted by none of those sophistical contrivances wherewith we are so industriously plied and belabored--contrivances such as groping for some middle ground between right and wrong: vain as the search for a man who should be neither a living man nor a dead man; such as a policy of 'don't care' on a question about which all true men do care; such as Union appeals beseeching true Union men to yield to Disunionists, reversing the divine rule, and calling, not the sinners, but the righteous to repentance; such as invocations to Washington, imploring men to unsay what Washington said and undo what Washington did. "Neither let us be slandered from our duty by false accusations against us, nor frightened from it by menaces of destruction to the government, nor of dungeons to ourselves. Let us have faith that right makes might, and in that faith let us to the end dare to do our duty as we understand it."
