Language is not essential for the cognitive processes that underlie thought

>And in fact, most of the things that you probably learned about the world, you learned through language and not through direct experience with the world.

Most things we know, we are probably not aware of. And for most of us, direct experience of everything that surrounds us in the world certainly exceeds by several order of magnitude the best bandwidth we can ever dream to achieve through any human language.

Ok, there are no actual data to back this, but authors of the article don't have anything solid either to back such a bold statement, from what is presented in the article.

If most of what we know of the world would mostly be things we were told, it would obviously be mostly a large amount of phatic noises, lies and clueless random assertions that we would have no mean to distinguish from the few stable credible elements inferable by comparing with a far more larger corpus of self experiments with realty.
