self-reference

Self-reference refers to the concept where something refers to itself in some way. In general knowledge, this can be seen in statements or works that discuss their own nature or characteristics. For example, a book about books or a sentence that talks about itself, like "This sentence is five words long." Self-reference often raises interesting questions about meaning, truth, and contradiction, and can be found in various fields, including literature, mathematics, and philosophy. It invites deeper reflection on the relationships between concepts and their representations.
