“While, then, every part of our country thus feels an immediate and particular interest in Union, all the parts combined cannot fail to find in the united mass of means and efforts greater strength, greater resource, proportionably greater security from external danger, a less frequent interruption of their peace by foreign nations; and, what is of inestimable value, they must derive from Union an exemption from those broils and wars between themselves, which so frequently afflict neighbouring countries not tied together by the same governments, which their own rivalships alone would be sufficient to produce, but which opposite foreign alliances, attachments, and intrigues would stimulate and embitter. Hence, likewise, they will avoid the necessity of those overgrown military establishments, which, under any form of government, are inauspicious to liberty, and which are to be regarded as particularly hostile to Republican Liberty. In this sense it is, that your Union ought to be considered as a main prop of your liberty, and that the love of the one ought to endear to you the preservation of the other.”

Context: We aspire to nothing that belongs to others. We seek no dominion over our fellow man, but man's dominion over tyranny and misery. But more is required. Men want to be a part of a common enterprise—a cause greater than themselves. Each of us must find a way to advance the purpose of the Nation, thus finding new purpose for ourselves. Without this, we shall become a nation of strangers.

1860s
Context: 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, if it was intended to be broken by every member of the Confederacy at will. It is 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 all 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 and the Government disrupted, I shall return to my native State and share the miseries of my people, and, save in defense will draw my sword on none.
