The Sapir–Whorf hypothesis is the ancient Roman theory of how rhetoric influences people, taken seriously as a scientific hypothesis (with "rhetoric" switched out for language in general). It is now generally believed to be true.
Example:
- The New York Times calls Sicko a "cinematic indictment of the American health care system." The film is generating significant buzz and is sure to spur a lively conversation about health coverage, care, and quality in America. While legislators, litigators, and patient groups are growing excited, others among us are growing anxious.
