so, my postulation is:
the knowledge we gain shapes our thinking. Language itself is the transportation medium for the knowledge. Is the medium is small, so the knowledge described with the medium is also "small" or "not destinctive enough". We can use a "second" language then to make the knowledge more exact and mor destinct/tdefined.
But the knowledge can also be gained with other means - learning by doing, as exmaple. So, a language is not necessary to gain knowledge (numb and deaf and blind people also think, but are somehow limited in their expression ...)
so based on that, I postulate, it's a coincidence when a language shapes our thinking, but the cause and the "affecting part" is the real "knowledge-transfer" by the language. No matter if its sign language, pointing towards .. speaking piraha or russian or finnish-english.
As a result thinking in Latin is absolutely different than thinking in English which has yes/no questions that could not exist in Latin. When asked a yes/no question without receiving a yes or no answer English speakers immediately assume deception and that assumption is almost always correct. The exception is when the answering party fully fails to grasp the question, or the question's intent if the question is vague or itself deceptive. In Latin language answers without a yes or no were the default and even though there is not an option to apply a direct yes or no answer many times deception was none the less assumed regardless due to differing cultural norms, especially in elevated classes.

For example, in one of the languages I speak, husban and wife literally means owner and woman. So a woman would say that he is her owner, while the man would say that she is his woman.
Some languages have different “you” meanings. There is a “you” for someone you know, a formal “you”, a “you” when addressing someone older than yourself.
While these things sound minor, I do believe they shape the thinking of individuals and societies.
I have a blog post draft about it, and now you reminded me that I should probably proofread it and publish.
That said the culture (relegion and other stories) we live in completely drive our cognition.
Culture & Ideology Are Not Your Friends (Terence McKenna) [FULL]
Presented at the Whole Life Expo, Denver, April 1999
Consciousness (existential inflection) and conscious (aware) are two separate things. Consciousness envelops one’s conscious experience, however there is much more (an entire mind technology.)
The mechanics of language and their influence on thought is yet another fascinating layer.
The apparatus of our minds which shape our thoughts are a technology. You shaping your thoughts is just as distinctive as your voice shaping your words. Many have a wide range of variability. There are many influences.
The technology of thought in our minds changes a great deal about who we are and how we interface with the world (more than just words and people.)
What is useful is not which language, for every modern language is mature through countless generations “polishing” it. What is useful is how much experience one has, and how they might articulate how this was processed.
The technology of the mind may at times seem like an arms race, though it is also like an ouroboros, devouring itself and reinventing through time.
If you want to think interesting thoughts, you need to think hard about things for a long time. That's the sine qua non of it. It can be in any language you want, or even in a nonlinguistic substrate like mental visualization. I would heavily caution people away from trying to shortcut this process by first spending 5 years studying e.g. ancient Assyrian and only then attempting to commune with pre-biblical demons (or whatever it is people think they want to do with this - if there's no particular goal in mind, I would say that's yet another red flag).
In general, I'm sorry to say, I think language learning is a tremendous waste of time and effort for almost everybody. Exceptions are mainly for hobbyists (even then, there are probably much more worthwhile hobbies you could take up), passing regulatory hurdles (all of mine so far), and integrating into a new culture (Finnish alone so far). If you want a pastime which will really push your brain to think hard and in new ways, philosophy and mathematics are both much better bang for your buck.
