a language might be a tool we use, but it absolutely shapes the way we see the world itself to a significant degree, even to the point where speakers of different languages might disagree on basic physical facts
eg: if you ask an english speaker how many fingers they have - they’ll answer 10. but if you answer a polish speaker - they’ll answer 20. polish makes little linguistic distinction between fingers, and how we call them, foot fingers
this is one example of many. i find it deeply fascinating and quite scary. it feels weird to realise that my understanding of the world is broadened and structured better thanks to the fact i use a language to describe it, but there might be things i’ll never notice, or will always confuse, simply because the tool i use is not perfect, and yet, that is the basis through which i perceive the world
