“Was it possible to lose the nation, and yet preserve the constitution? By general law life and limb must be protected; yet often a limb must be amputated to save a life; but a life is never wisely given to save a limb. I felt that measures, otherwise unconstitutional, might become lawful, by becoming indispensable to the preservation of the constitution, through the preservation of the nation.”

Context: Was it possible to lose the nation, and yet preserve the constitution? By general law life and limb must be protected; yet often a limb must be amputated to save a life; but a life is never wisely given to save a limb. I felt that measures, otherwise unconstitutional, might become lawful, by becoming indispensable to the preservation of the constitution, through the preservation of the nation. Right or wrong, I assumed this ground, and now avow it. I could not feel that, to the best of my ability, I had even tried to preserve the constitution, if, to save slavery, or any minor matter, I should permit the wreck of government, country, and Constitution all together.

1860s, First State of the Union address (1861)
Context: The war continues. In considering the policy to be adopted for suppressing the insurrection I have been anxious and careful that the inevitable conflict for this purpose shall not degenerate into a violent and remorseless revolutionary struggle. I have therefore in every case thought it proper to keep the integrity of the Union prominent as the primary object of the contest on our pan, leaving all questions which are not of vital military importance to the more deliberate action of the Legislature. In the exercise of my best discretion I have adhered to the blockade of the ports held by the insurgents, instead of putting in force by proclamation the law of Congress enacted. at the late session for closing those ports. So also, obeying the dictates of prudence, as well as the obligations of law, instead of transcending I have adhered to the act of Congress to confiscate property used for insurrectionary purposes. If a new law upon the same subject shall be proposed, its propriety will be duly considered. The Union must be preserved, and hence all indispensable means must be employed. We should not be in haste to determine that radical and extreme measures, which may reach the loyal as well as the disloyal, are indispensable.

Context: The great task of this generation, in my view, is to save democracy, to preserve it and to inspire it. The ideal of democracy is a very fine one, but no ideals can run of themselves... All government of the people can be presented, as it were, on the circumference of a wheel, and government runs in very varying degree from the most complete and absolute autocracy, step by step, to chaos, and you find instances in history of governments passing through every phase on that circumference... Now we are at a point in that wheel, and that point is Democracy, with representative government. We have to remember that the price of liberty is eternal vigilance, and, I may add, eternal knowledge, eternal sympathy, and eternal understanding; and it is our duty in this generation to keep the State steady at the point to which we have attained, knowing full well the risks that lie on either hand by slipping back in the one direction of the wheel or the other, the one direction drawing to a curtailment of our liberty, the other direction being that in which liberty tends to licence.
