单选题I received Everett"s Life of Washington which you sent me, and enjoyed its perusal. How his spirit would be grieved could he see the wreck of his mighty labors! I will not, however, permit myself to believe, until all ground of hope is gone, that the fruit of his noble deeds will be destroyed, and that his precious advice and virtuous example will so soon be forgotten by his countrymen. As far as I can judge by the papers, we are between a state of anarchy and civil war. May God avert both of these evils from us! I see that four states had declared themselves out of the Union; four more will apparently follow their example. Then, if the border states are brought into the gulf of revolution, one half of the country will be arrayed against the other. I must try and be patient and await the end, for I can do nothing to hasten or retard it. The South, in my opinion, has been aggrieved by the acts of the North, as you say. I feel the aggression and am willing to take every proper step for redress. It is the principle I contend for, not individual or private benefit. As an American citizen, I take great pride in my country, her prosperity and institutions, and would defend any state if her rights were invaded. But I can anticipate no greater calamity for the country than a dissolution of the Union. It would be an accumulation of all the evils we complain of, and I am willing to sacrifice everything but honor for its preservation. I hope, therefore, that all constitutional means will be exhausted before there is a resort to force. Secession is nothing but revolution. The framers of our Constitution never exhausted so much labor, wisdom, and forbearance in its formation, and surrounded it with so many guards and securities, for it was intended to be broken by every member of the Confederacy at will. It was intended for " perpetual union, " so expressed in the preamble, and for the establishment of a government, not a compact, which can only be dissolved by revolution or the consent of all the people in convention assembled. It is idle to talk of secession. Anarchy would have been established, and not a government, by Washington, Hamilton, Jefferson, Madison, and the other patriots of the Revolution ... Still, a Union that can only be maintained by swords and bayonets, and in which strife and civil war are to take the place of brotherly love and kindness, has no charm for me. I shall mourn for my country and for the welfare and progress of mankind. If the Union is dissolved, I shall return to my native state and share the miseries of my people; and, save in defense, will draw my sword on none.
