“Harshness towards individuals who flout the laws and commands of state is for the public good; no greater crime against the public interest is possible than to show leniency to those who violate it.”

Context: Let us, as we value our own self-respect, face the responsibilities with proper seriousness, courage, and high resolve. We must demand the highest order of integrity and ability in our public men who are to grapple with these new problems. We must hold to a rigid accountability those public servants who show unfaithfulness to the interests of the nation or inability to rise to the high level of the new demands upon our strength and our resources. Of course we must remember not to judge any public servant by any one act, and especially should we beware of attacking the men who are merely the occasions and not the causes of disaster.

Context: Even after the end of the Cold War we are […] faced with the task of tearing down the walls between different concepts of life, in other words the walls in people's minds that make it difficult time and again to understand one another in this world of ours. This is why the ability to show tolerance is so important. While, for us, our way of life is the best possible way, others do not necessarily feel that way. There are different ways to create peaceful coexistence. Tolerance means showing respect for other people's history, traditions, religion and cultural identity. But let there be no misunderstanding: Tolerance does not mean "anything goes". There must be zero tolerance towards all those who show no respect for the inalienable rights of the individual and who violate human rights.

Order of Retaliation http://quod.lib.umich.edu/l/lincoln/lincoln6/1:755?rgn=div1;view=fulltext (30 July 1863); quoted in Roy P. Basler, ed., The Collected Works of Abraham Lincoln, vol. 7 (New Brunswick, N.J.: Rutgers University Press, 1953), p. 357
1860s
Context: It is the duty of every government to give protection to its citizens, of whatever class, color, or condition, and especially to those who are duly organized as soldiers in the public service. The law of nations and the usages and customs of war as carried on by civilized powers, permit no distinction as to color in the treatment of prisoners of war as public enemies. To sell or enslave any captured person, on account of his color, and for no offence against the laws of war, is a relapse into barbarism and a crime against the civilization of the age. The government of the United States will give the same protection to all its soldiers, and if the enemy shall sell or enslave anyone because of his color, the offense shall be punished by retaliation upon the enemy's prisoners in our possession. It is therefore ordered that for every soldier of the United States killed in violation of the laws of war, a rebel soldier shall be executed; and for every one enslaved by the enemy or sold into slavery, a rebel soldier shall be placed at hard labor on the public works and continued at such labor until the other shall be released and receive the treatment due to a prisoner of war

1900s, Address at the Prize Day Exercises at Groton School (1904)
Context: You often hear people speaking as if life was like striving upward toward a mountain peak. That is not so. Life is as if you were traveling a ridge crest. You have the gulf of inefficiency on one side and the gulf of wickedness on the other, and it helps not to have avoided one gulf if you fall into the other. It shall profit us nothing if our people are decent and ineffective. It shall profit us nothing if they are efficient and wicked. In every walk of life, in business, politics; if the need comes, in war; in literature, science, art, in everything, what we need is a sufficient number of men who can work well and who will work with a high ideal. The work can be done in a thousand different ways. Our public life depends primarily not upon the men who occupy public positions for the moment, because they are but an infinitesimal fraction of the whole. Our public life depends upon men who take an active interest in that public life; who are bound to see public affairs honestly and competently managed; but who have the good sense to know what honesty and competency actually mean. And any such man, if he is both sane and high-minded, can be a greater help and strength to any one in public life than you can easily imagine without having had yourselves the experience. It is an immense strength to a public man to know a certain number of people to whom he can appeal for advice and for backing; whose character is so high that baseness would shrink ashamed before them; and who have such good sense that any decent public servant is entirely willing to lay before them every detail of his actions, asking only that they know the facts before they pass final judgment.
