“The Venezuelans ought to become inspired by the Honduran model, and strive for a change of government as soon as possible, through pacific, democratic, and constitutional means--and not just electoral--to avoid a national tragedy.”

Post-Presidency, Nobel lecture (2002)
Context: The world has changed greatly since I left the White House. Now there is only one superpower, with unprecedented military and economic strength. The coming budget for American armaments will be greater than those of the next fifteen nations combined, and there are troops from the United States in many countries throughout the world. Our gross national economy exceeds that of the three countries that follow us, and our nation's voice most often prevails as decisions are made concerning trade, humanitarian assistance, and the allocation of global wealth. This dominant status is unlikely to change in our lifetimes.
Great American power and responsibility are not unprecedented, and have been used with restraint and great benefit in the past. We have not assumed that super strength guarantees super wisdom, and we have consistently reached out to the international community to ensure that our own power and influence are tempered by the best common judgment.
Within our country, ultimate decisions are made through democratic means, which tend to moderate radical or ill-advised proposals. Constrained and inspired by historic constitutional principles, our nation has endeavored for more than two hundred years to follow the now almost universal ideals of freedom, human rights, and justice for all.

Essentials to Peace (1953)
Context: I believe our students must first seek to understand the conditions, as far as possible without national prejudices, which have led to past tragedies and should strive to determine the great fundamentals which must govern a peaceful progression toward a constantly higher level of civilization. There are innumerable instructive lessons out of the past, but all too frequently their presentation is highly colored or distorted in the effort to present a favorable national point of view. In our school histories at home, certainly in years past, those written in the North present a strikingly different picture of our Civil War from those written in the South. In some portions it is hard to realize they are dealing with the same war. Such reactions are all too common in matters of peace and security. But we are told that we live in a highly scientific age. Now the progress of science depends on facts and not fancies or prejudice. Maybe in this age we can find a way of facing the facts and discounting the distorted records of the past.

1860s, "If Slavery Is Not Wrong, Nothing Is Wrong" (1864)
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.
