I've just finished reading "The name of the rose" by Umberto Eco, a postmodern philosopher. At the end of the book he explains that according to him, titles should not be clear. Which is why he chose "The name of the rose", because the word rose has so much meanings, that it loses any specific meaning.
According to Eco titles should not explain the book. I believe he says this would influence the reader too much. Also, he argues against authors explaining their work. He says that ideally, the author would die after writing a book, so as not to influence any potential readers.
I've frequently encountered a similar sentiment amongst other postmodern philosophers, and I don't really understand where their aversion to explanation, or clarity (as in: an obvious singular meaning) comes from. Why is explaining your work, or guiding your audience a faux pas in postmodernism?
