“Sick cultures show a complex of symptoms such as you have named...but a dying culture invariably exhibits personal rudeness. Bad manners. Lack of consideration for others in minor matters. A loss of politeness, of gentle manners, is more significant than is a riot.”

American science fiction author, engineer, and naval officer

Robert A. Heinlein was an American science fiction author, engineer, and naval officer. He is known as a major figure in twentieth-century science fiction, and is sometimes called the “dean of science fiction writers.” He was among the first writers to stress scientific accuracy in fiction, helping shape hard science fiction. His fiction and nonfiction often praise competence, encourage critical thinking, and place characters in situations that test conventional social values. His influence remains visible in the genre and in wider culture.
