Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), known by his pen name Mark Twain, was an American writer, humorist, entrepreneur, publisher, and lecturer. He was lauded as the "greatest humorist this country has produced", and William Faulkner called him "the father of American literature". His novels include The Adventures of Tom Sawyer (1876) and its sequel, the Adventures of Huckleberry Finn (1885), the latter often called "The Great American Novel".

Simone Weil once said, "I would like to achieve the kind of radiance that can bring about nonviolently what other people might have to do violently." And, of course, we see teachers like that. We see parents like that, who have a kind of radiance so that they don't have to raise their voice; they don't have to beat their children. . . . They simply make a different atmosphere.
