“All the world had been at cross-purposes, had misunderstood themselves and the situation, had followed wrong paths, drawn wrong conclusions, and had known none of the facts. One would have done better to draw no conclusions at all. One's diplomatic education was a long mistake.”

The Devil and Daniel Webster (1937)
Context: He started off in a low voice, though you could hear every word. They say he could call on the harps of the blessed when he chose. And this was just as simple and easy as a man could talk. But he didn't start out by condemning or reviling. He was talking about the things that make a country a country, and a man a man.
And he began with the simple things that everybody's known and felt — the freshness of a fine morning when you're young, and the taste of food when you're hungry, and the new day that's every day when you're a child. He took them up and he turned them in his hands. They were good things for any man. But without freedom, they sickened. And when he talked of those enslaved, and the sorrows of slavery, his voice got like a big bell. He talked of the early days of America and the men who had made those days. It wasn't a spread-eagle speech, but he made you see it. He admitted all the wrong that had ever been done. But he showed how, out of the wrong and the right, the suffering and the starvations, something new had come. And everybody had played a part in it, even the traitors.

The Great Infidels (1881)
Context: The greatest men the world has produced have known but little. They had a few facts, mingled with mistakes without number. In some departments they towered above their fellows, while in others they fell below the common level of mankind.
