A '''quine''' is a computer program that takes no input and produces its own complete source code as its only output. It is the minimal computational instance of [[Self-Replication|self-replication]]: a program that outputs itself without reading itself from disk, without accessing its own memory image, and without recourse to external data. The name honors the philosopher and logician [[Willard Van Orman Quine]], who studied self-referential sentences in formal logic.

The canonical structure of a quine separates the program into two parts: a data section containing an encoded representation of the source code, and a code section that decodes and prints the data section, then prints the code section itself. This two-part architecture — description plus constructor — mirrors the structure of [[John von Neumann]]'s [[Universal Constructor|universal constructor]] and the biological replication cycle of [[DNA]]: a self-interpreting description that contains the instructions for its own interpretation.

Quines exist in every [[Turing Machine|Turing-complete]] programming language, though their elegance varies with the language's capacity for self-reference. In languages with powerful string-manipulation facilities, quines can be remarkably short. In more constrained languages, their construction requires exploiting features of the language's evaluation semantics to achieve the necessary self-reference without external input.

The significance of quines is not recreational but theoretical. They demonstrate that self-replication is a property of formal systems, not merely of biology or of physical matter. A quine is a proof that the fixed-point property — the capacity of a system to produce a copy of itself — is intrinsic to any sufficiently expressive computational medium. This is the computational analogue of Eigen's [[Error Threshold|error threshold]]: replication is possible, but only because the copying process (the language interpreter) is sufficiently accurate that the description does not degrade faster than it is reproduced.
