“A nation lives forever through its concepts, honor, and culture. It is for these reasons that the rulers of nations must judge and act not only on the basis of physical and material interests of the nation but on the basis of the nation's historical honor, of the nation's eternal interests. Thus: not bread at all costs, but honor at all costs.”

Not by Lincoln, this is apparently paraphrased from remarks about honoring him by Hugh Gordon Miller: "I do not believe in forever dragging over or raking up some phases of the past; in some respects the dead past might better be allowed to bury its dead, but the nation which fails to honor its heroes, the memory of its heroes, whether those heroes be living or dead, does not deserve to live, and it will not live, and so it came to pass that in 1909 nearly a hundred millions of people [...] were singing the praises of Abraham Lincoln." — from [http://www.archive.org/details/reportsons00sonsuoft "Lincoln, the Preserver of the Union" (22 February 1911), an address to the Sons of the Revolution in the State of New York.

Judicial opinions
Context: National unity is the basis of national security. To deny the legislature the right to select appropriate means for its attainment presents a totally different order of problem from that of the propriety of subordinating the possible ugliness of littered streets to the free expression opinion through handbills.

1860s, First State of the Union Address (1869)
Context: As the United States is the freest of all nations, so, too, its people sympathize with all people struggling for liberty and self-government; but while so sympathizing it is due to our honor that we should abstain from enforcing our views upon unwilling nations and from taking an interested part, without invitation, in the quarrels between different nations or between governments and their subjects. Our course should always be in conformity with strict justice and law, international and local.

1963, Speech at Amherst College

1950s, Second Inaugural Address (1957)
Context: We look upon this shaken Earth, and we declare our firm and fixed purpose — the building of a peace with justice in a world where moral law prevails. The building of such a peace is a bold and solemn purpose. To proclaim it is easy. To serve it will be hard. And to attain it, we must be aware of its full meaning — and ready to pay its full price. We know clearly what we seek, and why. We seek peace, knowing that peace is the climate of freedom. And now, as in no other age, we seek it because we have been warned, by the power of modern weapons, that peace may be the only climate possible for human life itself. Yet this peace we seek cannot be born of fear alone: it must be rooted in the lives of nations. There must be justice, sensed and shared by all peoples, for, without justice the world can know only a tense and unstable truce. There must be law, steadily invoked and respected by all nations, for without law, the world promises only such meager justice as the pity of the strong upon the weak. But the law of which we speak, comprehending the values of freedom, affirms the equality of all nations, great and small. Splendid as can be the blessings of such a peace, high will be its cost: in toil patiently sustained, in help honorably given, in sacrifice calmly borne.
