Etymology: Willard Van Orman Quine, the American logician, gave his name to a computer program that prints its own source code. The honour came from Douglas Hofstadter, who in his 1979 book Gödel, Escher, Bach described such programs but called them "self-reps." Quine's name was attached to a related idea: his study of self-reference, especially the statement "'Yields falsehood when preceded by its quotation' yields falsehood when preceded by its quotation," which produces a paradox when read closely. The name stuck because it fit a wordplay Quine had himself explored. Quine's work on self-reference is the root of the term's logic, and the programs echo the way a sentence can refer to, and reproduce, its own form. The word itself comes through Latin "quīnī," meaning "five at a time," and ultimately from a Proto-Indo-European root meaning "five" and "hand." The Latin sense of grouping by fives is not connected to the computing meaning, which owes its existence entirely to the surname.
