“Silence will create respect and dignity; justice and fairplay will bring more friends; benevolence and charity will enhance prestige and position; courtesy will draw benevolence; service of mankind will secure leadership and good words will overcome powerful enemies.”

1860s, What the Black Man Wants (1865)
Context: In regard to the colored people, there is always more that is benevolent, I perceive, than just, manifested towards us. What I ask for the negro is not benevolence, not pity, not sympathy, but simply justice. The American people have always been anxious to know what they shall do with us... I have had but one answer from the beginning. Do nothing with us! Your doing with us has already played the mischief with us. Do nothing with us! If the apples will not remain on the tree of their own strength, if they are worm-eaten at the core, if they are early ripe and disposed to fall, let them fall! … And if the negro cannot stand on his own legs, let him fall also. All I ask is, give him a chance to stand on his own legs! Let him alone! If you see him on his way to school, let him alone, don't disturb him! If you see him going to the dinner table at a hotel, let him go! If you see him going to the ballot box, let him alone, don't disturb him! If you see him going into a work-shop, just let him alone, — your interference is doing him positive injury.

Context: I wish the art of benefiting men had kept pace with the art of destroying them; for though war has become slow, philanthropy has remained hasty. The most melancholy of human reflections, perhaps, is that, on the whole, it is a question whether the, benevolence of mankind does most good or harm. Great good, no doubt, philanthropy does, but then it also does great evil. It augments so much vice, it multiplies so much suffering, it brings to life such great populations to suffer and to be vicious, that it is open to argument whether it be or be not an evil to the world, and this is entirely because excellent people fancy that they can do much by rapid action — that they will most benefit the world when they most relieve their own feelings; that as soon as an evil is seen "something" ought to be done to stay and prevent it.

Draft of a letter to the Grand Lodge of Free Masons of the State of Maryland (8 November 1798) http://memory.loc.gov/mss/mgw/mgw4/113/0400/0495.jpg
1790s
Context: So far as I am acquainted with the principles & Doctrines of Free Masonry, I conceive it to be founded in benevolence and to be exercised only for the good of mankind. If it has been a Cloak to promote improper or nefarious objects, it is a melancholly proof that in unworthy hands, the best institutions may be made use of to promote the worst designs.

2010s, 2018, Farewell statement (2018)
Context: I have tried to serve our country honorably. I have made mistakes, but I hope my love for America will be weighed favorably against them.
I have often observed that I am the luckiest person on Earth. I feel that way even now as I prepare for the end of my life. I have loved my life, all of it. I have had experiences, adventures and friendships enough for ten satisfying lives, and I am so thankful. Like most people, I have regrets. But I would not trade a day of my life, in good or bad times, for the best day of anyone else’s.
I owe that satisfaction to the love of my family. No man ever had a more loving wife or children he was prouder of than I am of mine. And I owe it to America. To be connected to America’s causes — liberty, equal justice, respect for the dignity of all people — brings happiness more sublime than life’s fleeting pleasures. Our identities and sense of worth are not circumscribed but enlarged by serving good causes bigger than ourselves.
"Fellow Americans" — that association has meant more to me than any other. I lived and died a proud American. We are citizens of the world’s greatest republic, a nation of ideals, not blood and soil. We are blessed and are a blessing to humanity when we uphold and advance those ideals at home and in the world. We have helped liberate more people from tyranny and poverty than ever before in history. We have acquired great wealth and power in the process.

Variant: In the end, we will remember not the words of our enemies, but the silence of our friends.

Autobiography (1873)
Context: What we principally thought of, was to alter people's opinions; to make them believe according to evidence, and know what was their real interest, which when they once knew, they would, we thought, by the instrument of opinion, enforce a regard to it upon one another. While fully recognizing the superior excellence of unselfish benevolence and love of justice, we did not expect the regeneration of mankind from any direct action on those sentiments, but from the effect of educated intellect, enlightening the selfish feelings.
