Eco, Umberto (1932-) Italian semiotician and novelist who claims that, while the interpretation of a text may indeed be influenced by tradition and reader whims, there is nevertheless

a meaning in the text that transcends these factors and cannot be simply discarded (as deconstructionsists claim). Perhaps his most influential works in the area

of text interpretation are The Role of the Reader (1979) and The Limits of Interpretation (1990).
