The principal characteristic of intelligent agency is choice. “Intelligent” derives from two Latin words, the preposition inter, meaning between, and the verb lego, meaning to choose or select. Thus, according to its etymology, intelligence consists in choosing between. For an intelligent agent to act is therefore to choose from a range of competing possibilities. . . . Actualizing one among several competing possibilities, ruling out the rest, and specifying the one that was actualized encapsulates how we recognize intelligent agency, or equivalently, how we detect design, (W. A. Dembski)
