“The happy and powerful do not go into exile, and there are no surer guarantees of equality among men than poverty and misfortune.”

1850s, The Present Aspect of the Slavery Question (1859)
Context: Such is the present aspect of the slavery question. For myself, I believe that the faith in which the government was founded still survives. I believe that the spirit of despotism which now says to the country, 'I will rule or ruin', will hear the imperial voice of the conscience of the American people, recognizing that justice and prosperity walk hand in hand, saying, 'You will do neither'. I believe that God did not hide this continent through all time as the spot whereon a nation should be planted upon the only principle that can render a nation as permanent as the race, to suffer the experiment to fail within a century. I believe these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain inalienable rights, that among these are life, liberty, and the pursuit of happiness. Do you believe it? If aye, let us go into the battle, and God speed the right.

Also quoted as: Doing what's right is no guarantee against misfortune. Paraphrased variant: "People don't ever seem to realize that doing what's right's no guarantee against misfortune."

Education (1902)
Context: I am not of those who believe in lackadaisical methods. On the contrary, I advocate a vigorous, thorough, exact mental training which shall fit the mind to expand upon and grasp large things and yet properly to perceive in their just relation the significance of small ones to discriminate accurately as to quantity and quality and thus to develop individual judgment, capacity and independence.
But at the same time I am of those who believe that gentleness is a greater, surer power than force, and that sympathy is a safer power by far than is intellect. Therefore would I train the individual sympathies as carefully in all their delicate warmth and tenuity as I would develop the mind in alertness, poise and security.
Nor am I of those who despise dreamers. For the world would be at the level of zero were it not for its dreamers gone and of today. He who dreamed of democracy, far back in a world of absolutism, was indeed heroic, and we of today awaken to the wonder of his dream.

Context: He was sick of having to be afraid. It was a situation to drive a man right out of his skull. If he stopped being afraid, even for an instant, he could be killed! But now, at least for the moment, he could stop listening for footsteps, stop trying to look in all directions at once. A sonic stunner was a surer bet than a hypothetical, undependable psi power. It was real, cold and hard in his hand.

Context: We have introduced the monetary factor not by necessity but by choice. Its advantages are obvious. Self-financed commodity units are not only interest free, but free also from dependence upon credit conditions. They are a step-desirable, it seems to us-in the direction of a goods economy as distinct from a money economy; but this step is taken without violence by merely identifying basic goods with money. It guarantees unfailing purchasing power where it is most needed-among the countless producers of raw commodities.
