Toute l’expérience d’un individu est construit sur le plan de son langage.
[An individual’s experience is built entirely in terms of his language.]
[An individual’s experience is built entirely in terms of his language.]
The strong hypothesis says that language determines and bounds your thinking, the weak hypothesis is that it influences and conditions your thinking.

It's really unclear to me that much harm will be done if everyone speaks the same language, and it's clear to me that there will be great benefits. That's an easy position for me to take as a primary speaker of the world's dominant language. It's also no skin off my back if other language groups wish to continue maintaining their own languages. But I guess that those which aren't strong enough will fade over the centuries, as many already did in the past.
This is even true in math. Based on the set of axioms you allow, you can prove certain facts. A math with different axioms may have completely different theorems, and some observable real world behavior can be better modeled under one set of axioms than another.
Language could be described as a math for personal expression and everyday life, and each language has its own axioms and theorems.
I am very skeptical that this happens commonly, or that the necessary terms couldn't be ported over to the common language if needed.
