Who stated A classic is a book that has never finished saying what it to say?

The quote, "A classic is a book that has never finished saying what it has to say," is often attributed to Italo Calvino, though it is difficult to definitively say if he was the original author.

Here's what we know:

* Calvino's essay: The quote appears in Calvino's essay "Why Read the Classics?" (1981). He doesn't directly claim authorship of the quote, but uses it as a starting point for his discussion on the enduring value of classic literature.

* Other sources: Some sources claim the quote originated from T.S. Eliot, or perhaps from Ezra Pound, although no definitive evidence supports this.

* Common phrase: The core idea that classics have a timeless quality and continued relevance is a common sentiment among literary critics and enthusiasts.

Therefore, while the quote is often linked to Calvino, its exact origin remains somewhat unclear. Regardless, Calvino's essay and his own insights on classics are well worth exploring.
