“I don't know why it should be, I am sure; but the sight of another man asleep in bed when I am up, maddens me.”

1990s, Long Walk to Freedom (1995)
Context: It was during those long and lonely years that my hunger for the freedom of my own people became a hunger for the freedom of all people, white and black. I knew as well as I knew anything that the oppressor must be liberated just as surely as the oppressed. A man who takes away another man's freedom is a prisoner of hatred, he is locked behind the bars of prejudice and narrow-mindedness. I am not truly free if I am taking away someone else's freedom, just as surely as I am not free when my freedom is taken from me. The oppressed and the oppressor alike are robbed of their humanity.
When I walked out of prison, that was my mission, to liberate the oppressed and the oppressor both. Some say that has now been achieved. But I know that that is not the case. The truth is that we are not yet free; we have merely achieved the freedom to be free, the right not to be oppressed. We have not taken the final step of our journey, but the first step on a longer and even more difficult road. For to be free is not merely to cast off one's chains, but to live in a way that respects and enhances the freedom of others. The true test of our devotion to freedom is just beginning.

"Angel Surrounded by Paysans" (1949)
Context: I am one of you and being one of you
Is being and knowing what I am and know.
Yet I am the necessary angel of earth,
Since, in my sight, you see the earth again,
Cleared of its stiff and stubborn, man-locked set
And, in my hearing, you hear its tragic drone
Rise liquidly in liquid lingerings,
Like watery words awash; like meanings said
By repetitions of half-meanings. Am I not,
Myself, only half a figure of a sort,
A figure half seen, or seen for a moment, a man
Of the mind, an apparition appareled in
Apparels of such lightest look that a turn
Of my shoulders and quickly, too quickly, I am gone?

Comments to James H. Wilson (22 October 1864), as quoted in Under the Old Flag: Recollections of Military Operations in the War for the Union, the Spanish War, the Boxer Rebellion, etc Vol. 2 (1912) by James Harrison Wilson, p. 17.
1860s, 1864
Context: I am a damned sight smarter man than Grant. I know more about military history, strategy, and grand tactics than he does. I know more about supply, administration, and everything else than he does. I'll tell you where he beats me though and where he beats the world. He doesn't give a damn about what the enemy does out of his sight, but it scares me like hell. … I am more nervous than he is. I am more likely to change my orders or to countermarch my command than he is. He uses such information as he has according to his best judgment; he issues his orders and does his level best to carry them out without much reference to what is going on about him and, so far, experience seems to have fully justified him.
