The name of the finch
Did you read The name of the rose? I read it and saw the movie long time ago (when I was a teenager, a favorite). Some days ago, I found in Twitter a thread about the movie and there was a picture of the cover and on it there was this sentence: "Everything left from a rose is just its name". It sticked to my mind... I thought Humberto Eco chose the name of the book as a reply (contradictory) of the sentence said by Juliet by Shakespeare, so I went to dig up a little bit. I didn't find that was the case, but I ended up with two nice ideas. The first one is that I thought about The ship of Theseus, and about it I came to the conclusion that the ship of Theseus remains being the ship of Theseus only while it is still the ship of Theseus. I mean, it does no matter how much the ship change, if it is still defined by being a ship and belong to Theseus, as long as these two conditions are met (as long as the name is the same) the ship is still the same. That links with the rose because what I thought was a contradictory answer, Shakespeare saying that roses are the same even if we change the name, and Eco saying that roses are ephemeral (the individuals) and what remains is what we know about them (their name, the species name). A little bit the idea that only what we name is real (or we only value what we know, what we can name. That is also the reason why I name things, for them to be or appear more valuable). It seems that Eco with the title of the book was not trying to disagree with Shakespeare but it seems that for him titles (names) "should mix ideas, not regulate them" and from there I came out with the second idea. Eco thought that historians (like us with evolution) rebuild history from "pictures", small pieces of information (text for instance) that are only a glimpse of what reality is, and we (the historians) understand them as best as we can (given who we are and what we know, it means subjetively, https://www.historytoday.com/rose-any-other-name-umberto-eco-1932-2016). In that sense history only can be what we tell about it, I mean the idea, the idea of reality that we have in our minds (hence he wrote fiction). Therefore, the rose (the name) is also a picture, it is not permanent, is ephemeral and incomplete. The rose (the name, the species) is only a model that does not have all the information (about all individual roses) and it only lasts because we name it, because of what we know about the rose, because we use the name. I think that in the case of birds' names both apply: the names of the birds (or any species) have power because (and when) we use them, and their meaning change with the historical context, therefore if the historical context change it is possible (and sometimes necessary) changing the names, and still even if the name change it is still the same bird (species) that was before, unless the bird change (speciation) and if so we also need a new name.
