“Slavery has left behind it a spirit that still delights in human blood. Outrage, murder, and assassination are the inheritance of the freed men and women of the South. Neither our government nor our civilization seems able to stop the flow of blood. As in the time of slavery, the Church is silent.”

1870s, Seventh State of the Union Address (1875)
Context: Our liberties remain unimpaired; the bondmen have been freed from slavery; we have become possessed of the respect, if not the friendship, of all civilized nations. Our progress has been great in all the arts—in science, agriculture, commerce, navigation, mining, mechanics, law, medicine, etc.; and in general education the progress is likewise encouraging. Our thirteen States have become thirty-eight, including Colorado (which has taken the initiatory steps to become a State), and eight Territories, including the Indian Territory and Alaska, and excluding Colorado, making a territory extending from the Atlantic to the Pacific. On the south we have extended to the Gulf of Mexico, and in the west from the Mississippi to the Pacific.

Context: I have just been talking about forces of potential destruction that mankind has developed, and how we might control them. It is equally important that we remember the beneficial forces that we have evolved over the ages, and how to hold fast to them.
One of those constructive forces is enhancement of individual human freedoms through the strengthening of democracy, and the fight against deprivation, torture, terrorism and the persecution of people throughout the world. The struggle for human rights overrides all differences of color, nation or language.
Those who hunger for freedom, who thirst for human dignity, and who suffer for the sake of justice — they are the patriots of this cause.
I believe with all my heart that America must always stand for these basic human rights — at home and abroad. That is both our history and our destiny.
America did not invent human rights. In a very real sense, it is the other way round. Human rights invented America.
Ours was the first nation in the history of the world to be founded explicitly on such an idea. Our social and political progress has been based on one fundamental principle — the value and importance of the individual. The fundamental force that unites us is not kinship or place of origin or religious preference. The love of liberty is a common blood that flows in our American veins.
