Self-referenceA self-reference occurs when a statement refers to itself. Reference is possible when there are two logical levels, a level and a meta-level. It is most commonly used in mathematics, philosophy, computer programming, and linguistics. Self-referential statements can lead to paradoxes (but see antinomy for limits on the significance of these).
An example of a self-reference situation is the one of autopoļesis, as the logical organisation produces itself the physical structure which create itself.
