“I could not comprehend the justice of that law, or that religion, which upholds or recognizes the principle of slavery;”

1850s, The Present Aspect of the Slavery Question (1859)
Context: Our fathers, therefore, were fully alive to the scope of their words and their work; and thus, as I believe, the Constitution of the United States, in its essential spirit and intention, recognizes the essential manhood of Dred Scott as absolutely as it does that of the President, of the Chief Justice, or of any Senator of the United States. I think I have not unfairly stated the spirit of the age, the sentiments of the fathers, and the original doctrine of this government upon the question of slavery. The system was recognized by law, but it was considered an evil which Time was surely removing. And, as if to put this question at rest forever, to show that the framers of this government did not look forward to a continuance of slavery, Mr. Stephens of Georgia, the most sagacious of the living slavery leaders, says, in June of this year, 'The leading public men of the South, in our early history, were almost all against it. Jefferson was against it. This I freely admit, when the authority of their names is cited. It was a question which they did not, and perhaps could not, thoroughly understand at that time'.

1963, Civil Rights Address

1930s, Quarantine Speech (1937)
Context: Those who cherish their freedom and recognize and respect the equal right of their neighbors to be free and live in peace must work together for the triumph of law and moral principles in order that peace, justice, and confidence may prevail in the world. There must be a return to a belief in the pledged word, in the value of a signed treaty. There must be recognition of the fact that national morality is as vital as private morality.
