You must be blind or something because I linked real data that goes directly against what you said about Spanish scientific output. In fact, you were raving about all the "philosophy" Spanish doesn't have, despite Spain with its Spanish language literature often being one of the most important and highest-producing countries in terms of publications in philosophy and other humanities. Convenient for you to ignore it I guess.

You also said this:

The languages with the most intellectual capital are Western European languages like English, German. East Asian languages like Mandarin are growing intellectual capital.

Very clearly you thought that Mandarin has less intellectual capital than English and German, and that Mandarin was just "growing" but not actually ahead. Which is just not true, definitely not for German.

I can tell you have no idea about how rich scientific literature in other languages is, because you aren't involved in scientific literature and you don't speak other languages.

... evidence that Spain is in Western Europe? Or that throughout history, diversity in scientific ideas and the progress brought by said diversity have come in large part from language divides? You know, like, the entirety of medical history and modern-day biodiversity sciences? Or evidence that China surpasses the US and Germany in scientific production? Or how Spanish-language publications are extremely prevalent in many subjects, like linguistics, philosophy, social sciences, and humanities like archeology where they tend to surpass othern non Chinese/English speaking countries, and where Spain tends to have more importance than every country other than China, the US, and occasionally the UK?

It's easy to tell from the actual data that there's plenty of science in non-English languages, including Spanish, and many primarily Spanish-speaking countries have their own niches that they occupy (with Spain being one of the most influential forces in a lot of social sciences, humanities, and related subjects, and Argentina, Mexico, and Chile each especially pulling more than their weight in specific subjects).

Where exactly are you confused?

Western European languages like English, German

... and Spanish? Do you forget that Spain exists, is in Western Europe, and is where Spanish spread from, or? Spain alone produces around as many scientific publications as France, Italy, Japan, Australia, Canada, Russia, etc. depending on the year – impressive considering it's both less populated and poorer than those countries – and including Latin American countries like Chile, Mexico, and Colombia makes Spanish surpass all languages other than Chinese and English in amount of scientific literature. I'm also not sure where you got the idea that the German language contributes more to human knowledge than Chinese, China produces far more scientific output than the US and around 4-5x as much as Germany.

Something tells me you don't speak any 2nd language, you've never left the country, nor are you involved in academia or qualified scientific research at all, and you're trying to speak about things you don't know about. You're some sort of pseudo-intellectual who has no qualifications or talents, but thinks you're on the same level as actual philosophers by copy-pasting links of news articles about problems you don't actually know anything about to Reddit and Lemmy.

I work in a computational natural science and much of the general humanities, philosophy, linguistics, and psycholinguistics literature I've read from the modern era is in Spanish, and plenty of Spanish papers are incredibly rich & high quality despite them. It's impossible to ignore non-English languages' significant contributions to scientific knowledge, and especially the Spanish-speaking world's impact on modern science.

Regardless of that, the amount of papers about iguana mating written in a language isn't relevant at all to migrants. If anything, a population speaking different languages is a good thing for science, because that kind of separation encourages thinking about and discussing problems in a different way, and adopting different focuses or techniques. Throughout history, many divides in science coincided with language divides, with the most prominent scientific breakthroughs often coming from people in different "camps" which coincided with the language they spoke, e.g. the Arabic-speaking world would have their own views on a specific problem or field which eventually turned out to be the dominant view, and the Italian-speaking world, and the Greek-speaking world, and the Latin-speaking world, and the German-speaking world, and the Judeo-Spanish-speaking world, and the Akkadian-speaking world, Hebrew & Aramaic speaking world, and the Chinese-speaking world, and the French-speaking world... many languages encourages many forms of thinking, and encourages innovation.

The dominant languages in the US/UK/Canada, China, Germany, and France have the most scientific literature available because those countries' governments are able to spend an extremely large amount of money to subsidize and drive scientific research, and have large relatively well-off and well-educated populations to become scientists. With the US seeing an increasing number of Spanish-speakers in their population, it's likely it'll eventually see a large rise in Spanish-language scientific literature produced in the country at some point.
