“Well-intentioned men don’t run for office any more! They have too much sense to expose themselves to assassination, and only delusible idiots like our current chief executive can be persuaded to don the robes of high office. Nice guys don’t crave power.”

1870s, Eighth State of the Union Address (1876)
Context: It was my fortune, or misfortune, to be called to the office of Chief Executive without any previous political training. From the age of 17 I had never even witnessed the excitement attending a Presidential campaign but twice antecedent to my own candidacy, and at but one of them was I eligible as a voter.
Under such circumstances it is but reasonable to suppose that errors of judgment must have occurred. Even had they not, differences of opinion between the Executive, bound by an oath to the strict performance of his duties, and writers and debaters must have arisen. It is not necessarily evidence of blunder on the part of the Executive because there are these differences of views. Mistakes have been made, as all can see and I admit...

Letter to Lucy Webb Hayes, whose cousin was a prisoner and died at Andersonville prison (2 July 1864)
Diary and Letters of Rutherford Birchard Hayes (1922 - 1926)
Context: You use the phrase “brutal Rebels.” Don’t be cheated in that way. There are enough “brutal Rebels” no doubt, but we have brutal officers and men too. I have had men brutally treated by our own officers on this raid [to Lynchburg, Va. ]. And there are plenty of humane Rebels. I have seen a good deal of it on this trip. War is a cruel business and there is brutality in it on all sides, but it is very idle to get up anxiety on account of any supposed peculiar cruelty on the part of Rebels. Keepers of prisons in Cincinnati, as well as in Danville, are hard-hearted and cruel.

Inaugural address (1889)
Context: There is no constitutional or legal requirement that the President shall take the oath of office in the presence of the people, but there is so manifest an appropriateness in the public induction to office of the chief executive officer of the nation that from the beginning of the Government the people, to whose service the official oath consecrates the officer, have been called to witness the solemn ceremonial. The oath taken in the presence of the people becomes a mutual covenant. The officer covenants to serve the whole body of the people by a faithful execution of the laws, so that they may be the unfailing defense and security of those who respect and observe them, and that neither wealth, station, nor the power of combinations shall be able to evade their just penalties or to wrest them from a beneficent public purpose to serve the ends of cruelty or selfishness.

The Other World (1657)
Context: Most men judge only by their senses and let themselves be persuaded by what they see. Just as the man whose boat sails from shore to shore thinks he is stationary and that the shore moves, men turn with the earth under the sky and have believed that the sky was turning above them. On top of that, insufferable vanity has convinced humans that nature has been made only for them, as though the sun, a huge body four hundred and thirty-four times as large as the earth, had been lit only to ripen our crab apples and cabbages.
I am not one to give in to the insolence of those brutes. I think the planets are worlds revolving around the sun and that the fixed stars are also suns that have planets revolving around them. We can't see those worlds from here because they are so small and because the light they reflect cannot reach us. How can one honestly think that such spacious globes are only large, deserted fields? And that our world was made to lord it over all of them just because a dozen or so vain wretches like us happen to be crawling around on it? Do people really think that because the sun gives us light every day and year, it was made only to keep us from bumping into walls? No, no, this visible god gives light to man by accident, as a king's torch accidentally shines upon a working man or burglar passing in the street.

Context: Rick, I don't think I've ever hired an illegal in my life... We had a lawn company to mow our lawn, and they had illegal immigrants, and when that was pointed out to us, we let them go... So we went to the company and we said, "Look, you can't have any illegals working on our property. I'm running for office, for Pete's sake. I can't have illegals."
