“There is perhaps no truer sign that a man is really advancing than that he is learning to forget himself, that he is losing the natural thoughts about self in the thought of One higher than himself, to whose guidance he can commit himself and all men.”

Context: "Behold yon miserable creature. That Point is a Being like ourselves, but confined to the non-dimensional Gulf. He is himself his own World, his own Universe; of any other than himself he can form no conception; he knows not Length, nor Breadth, nor Height, for he has had no experience of them; he has no cognizance even of the number Two; nor has he a thought of Plurality; for he is himself his One and All, being really Nothing. Yet mark his perfect self-contentment, and hence learn this lesson, that to be self-contented is to be vile and ignorant, and that to aspire is better than to be blindly and impotently happy. Now listen."He ceased; and there arose from the little buzzing creature a tiny, low, monotonous, but distinct tinkling, as from one of your Spaceland phonographs, from which I caught these words, "Infinite beatitude of existence! It is; and there is none else beside It."

1850s, Speech at Peoria, Illinois (1854)
Context: "Fools rush in where angels fear to tread." At the hazard of being thought one of the fools of this quotation, I meet that argument — I rush in — I take that bull by the horns. I trust I understand and truly estimate the right of self-government. My faith in the proposition that each man should do precisely as he pleases with all which is exclusively his own lies at the foundation of the sense of justice there is in me. I extend the principle to communities of men as well as to individuals. I so extend it because it is politically wise, as well as naturally just: politically wise in saving us from broils about matters which do not concern us. Here, or at Washington, I would not trouble myself with the oyster laws of Virginia, or the cranberry laws of Indiana. The doctrine of self-government is right, — absolutely and eternally right, — but it has no just application as here attempted. Or perhaps I should rather say that whether it has such application depends upon whether a negro is not or is a man. If he is not a man, in that case he who is a man may as a matter of self-government do just what he pleases with him.
But if the negro is a man, is it not to that extent a total destruction of self-government to say that he too shall not govern himself. When the white man governs himself, that is self-government; but when he governs himself and also governs another man, that is more than self-government — that is despotism. If the negro is a man, why then my ancient faith teaches me that "all men are created equal," and that there can be no moral right in connection with one man's making a slave of another.

1950s, Conquering Self-centeredness (1957)
Context: I look at my little daughter every day and she wants certain things and when she wants them, she wants them. And she almost cries out, “I want what I want when I want it.” She is not concerned about what I think about it or what Mrs. King thinks about it. She wants it. She’s a child and that’s very natural and normal for a child. She is inevitably self-centered because she’s a child. But when one matures, when one rises above the early years of childhood, he begins to love people for their own sake. He turns himself to higher loyalties. He gives himself to something outside of himself. He gives himself to causes that he lives for and sometimes will even die for. He comes to the point that now he can rise above his individualistic concerns, and he understands then what Jesus meant when he says, “He who finds his life shall lose it; he who loses his life for my sake, shall find it.”’ In other words, he who finds his ego shall lose his ego, but he who loseth his ego for my sake, shall find it. And so you see people who are apparently selfish; it isn’t merely an ethical issue but it is a psychological issue. They are the victims of arrested development, and they are still children. They haven’t grown up. And like a modern novelist says about one of his characters, “Edith is a little country, bounded on the east and the west, on the north and the south, by Edith.” And so many people are little countries, bounded all around by themselves and they never quite get out of themselves. And these are the persons who are victimized with arrested development.
