Wittgenstein: Die Grenzen meiner Sprache bedeuten die Grenzen meiner Welt.
Passer-by: Where's that guy from? Is he Dutch?
I've never thought much of the Wittgenstein's argument. First, there's non-verbal thinking that can be used to escape the limits of the language. Second, once the knowledge is gained by non-verbal thinking, it can be used to extend the language itself and thus extend the limits of everyone's world.
However, I've been writing newspaper articles and a blog in Slovak lately and the experience made me think of the Wittgenstein quote.
Namely, I had hard time expressing some ideas and making some arguments. Slovak, you see, is a language of 5 million speakers, with ~200 years of history as a literary language. A lot of terms that one can use in English simply do not exist.
I can't say, for example:
I support policy X because it enables economies of scale and I am against policy Y because it introduces a single point of failure.
There are no widely accepted equivalents to "economies of scale" and "single point of failure".
I can say:
Som za X, pretože umožňuje úspory z rozsahu a som proti Y, pretože zavádza jediný bod zlyhania.
It's hard to relate how that sounds. Enough to say that "úspory z rozsahu" doesn't literally translate to "economies of scale" but rather to "savings from the extent". One gets an impression of a crackpot speaking gibberish, making a crackpot argument.
It should be said that this is not a problem in one-to-one conversations. One can use the English term if the other is aware of it, or, if not, he can clarify the meaning of the term in advance. Where the problem hits is the public discussion. There you can't expect the prior knowledge or afford extensive explanations. Attention span in public discussion is, after all, very limited. If you waste your one minute of public attention by explaining what a single point of failure is, you've already lost.
It can be argued that the problem lies not with the language, but rather with the language speakers: Slovaks are simple people, uneducated, they don't have the concept of economies of scale. Therefore, they should be educated and the term would force its way into the language all by itself.
But that, while true, is missing the point.
Most English speakers don't know what economies of scale are either. Yet, with 1.5 billion English speakers there's a large enough minority that does. They use the term, they write about it, they discuss it. If you encounter the term and you are not sure what it means you can google it and find out that there's a lot of hits, that some pretty serious people are discussing it, you can even learn what it means yourself. In any case, there's none of this "lonely crackpot" perception that you get if using a small language.
All in all, in small language communities, the limits of the language are the limits of the Overton window. Some policies are not on the table not because people are opposed to them but because they can't even discuss them.
It reminds me of what Joe Henrich says about small populations:
There are these great cases in the ethnohistorical record of groups like the Polar Inuit who get cut off from the rest of the Inuit population. Then they begin to lose valuable tools and technology because their own brains remain the same size, but their collective brain became severed. They’re not able to maintain as much know-how in the population.
I think you are on the wrong track. Of course, in the end you can find the equivalent term that someone used somewhere.
But look at it from a different perspective.
Take a term that is used and understood in the rationalist community. Say "Moloch".
Now try to write an opinion piece to The Washington Post. If you want to refer to the concept of "Moloch" you can either explain it, wasting your allotted 3000 characters quickly, or just say "Moloch" and hope someone would get it. In the latter case one or two people may get it and the rest would think you are a crackpot referring to the ancient Phoenician deity in a completely unrelated context.
The problem is that the rationalist community is too small for its terminology "to be in the Overton window". Not so with economic terminology. That community is large enough and the terms like "economies of scale" are admissible in public discourse.
Now scale that down to a small language community. Suddenly, the rationalist community is so small that it, for all practical purposes, does not exist. The economists are now in the position that the rationalists were in in the anglosphere. There are few of them and their terminology is not widely understood and accepted.
In other words: In the US you can't make an argument in public discussion involving rationalist concepts. But you can use economic terminology and get away with it. In Slovakia, you often can't.
