Umberto Eco (1932–2016) was an Italian semiotician, philosopher, literary critic, and novelist. His theoretical work spanned semiotics, aesthetics, and the philosophy of language. His novels, including The Name of the Rose (1980), apply semiotic themes in narrative form.
Core ideas
- A Theory of Semiotics (1976): Eco’s attempt at a unified semiotic theory. He distinguished a theory of codes (how sign systems are organized) from a theory of sign production (how signs are made and used). He proposed that semiotics should study everything that can be used to lie — because if a sign can be used to state something false, it is genuinely a sign and not merely a causal trace.
- Unlimited semiosis: drawing on Peirce’s concept that every interpretant is itself a sign, Eco argued that meaning is never final — each interpretation opens further interpretations. He explored the cultural and practical constraints that prevent interpretation from being merely arbitrary.
- The encyclopedia vs. dictionary model: Eco argued that meaning is organized not as a dictionary (fixed definitions) but as an encyclopedia (a network of interconnected cultural knowledge). The meaning of a sign is not a single concept but the entire web of interpretive possibilities that the sign activates in a given cultural context.
- The role of the reader: in The Role of the Reader (1979) and The Limits of Interpretation (1990), Eco analyzed how texts cooperate with readers to produce meaning. The “model reader” is the interpretive competence that a text presupposes; the “open work” is a text that deliberately invites multiple valid interpretations.
- Overcoding and undercoding: Eco distinguished situations where existing codes are applied in novel ways (overcoding) from situations where signs are interpreted without established codes (undercoding). Undercoding is the semiotic situation of encountering the genuinely new.
