The words automatic pilot or automatic transmission bring to mind mechanical devices that operate with minimal human intervention. Yet the word automatic, which goes back to the Greek word automatos, “acting of one's own will, self-acting, of itself,” is made up of two parts, auto-, “self,” and -matos, “willing,” is first recorded in English in 1748 with reference to motions of the body; such as, the peristaltic action of the intestines: “The Motions are called automatic from their Resemblance to the Motions of Automata, or Machines, whose Principle of Motion is within themselves.”
Although the writer had machines in mind, automatic could be used as a reference to living things, a use we still have. The association of automatic chiefly with machinery may represent one instance of many in which we have come to see the world in mechanical terms.
Technologies normally considered part of auto-ID include bar codes, biometrics, and voice recognition.
