It isn't easy to imagine our mind without language. We can't think, plan, or relate to other people if we lack words to structure our ideas.
Bertrand Russel stated that the task of language is to "make possible thoughts which could not exist without it."

A mind without language

Take language away, and the amount of information you can acquire decreases.
Many deaf children born into hearing families live in a world unable to communicate properly. They are never exposed to abstract ideas such as "justice" or "global warming." Unless the parents learn sign language, the child's language access will be delayed or missing entirely.

Language and acquiring information

The lack of language affects even functions like math. Keeping track of exact numbers above four requires knowing the words for these numbers. The language-number interdependency means many deaf children in industrialized societies fall behind in math because they did not learn to count.
Social cognition is another part of your mind that needs language to develop. Why is your mom upset? Understanding social situations requires inferring what people around you are thinking.

Non-linguistic limitations

Language can disappear after severe damage to the brain. It is known as aphasia - the inability to understand or produce speech.
Research on adults with aphasia has demonstrated that math, theory of mind, and other cognitive abilities are independent from language. Patients with aphasia perform comparably to the rest of us when asked to complete arithmetic tasks, reason about people's intentions, determine physical causes of actions, or decide whether a drawing represents a real-life event. Some can continue with creative tasks.

Adult individuals with aphasia

In adults, language is separate from other functions of the brain.
Our language is but a scaffold for our minds. It is indispensable during the formative years but can be done away with once the building is in place.

Can you think, plan, or relate to other people if you lack words to help structure your experiences?Many great thinkers have drawn a strong connection between language and the mind. Oscar Wilde called language “the parent, and not the child, of thought”; Ludwig Wittgenstein claimed that “the limits of my language mean the limits of my world”; and Bertrand Russell stated that the role of language is “to make possible thoughts which could not exist without it.”After all, language is what makes us human, what lies at the root of our awareness, our intellect, our sense of self. Without it, we cannot plan, cannot communicate, cannot think. Or can we?Imagine growing up without words. You live in a typical industrialized household, but you are somehow unable to learn the language of your parents. That means that you do not have access to education; you cannot properly communicate with your family other than through a set of idiosyncratic gestures; you never get properly exposed to abstract ideas such as “justice” or “global warming.” All you know comes from direct experience with the world.It might seem that this scenario is purely hypothetical. There aren’t any cases of language deprivation in modern industrialized societies, right? It turns out there are. Many deaf children born into hearing families face exactly this issue. They cannot hear and, as a result, do not have access to their linguistic environment. Unless the parents learn sign language, the child’s language access will be delayed and, in some cases, missing completely.<figure><img src="http://static.nautil.us/16436_3c8ebb190703254a2cb4ede547c4285c.png" width="733" alt="Ivanova_BREAKER" height="370"><figcaption dir="auto">INNER VOICES: A set of brain regions within the left hemisphere, shown in color, responds strongly and selectively to language, but not to other thought-related processes.</figcaption></figure>Does our mind develop normally under such circumstances? Of course not. Language enables us to receive vast amounts of information we would have never acquired otherwise. The details of your parents’ wedding. The Declaration of Independence. The entrée section of the dinner menu. The entire richness of human experience condensed into a linear sequence of words. Take language away, and the amount of information you can acquire decreases dramatically. The lack of language affects even functions that do not seem to be intrinsically “linguistic,” such as math. Developmental research shows that keeping track of exact numbers above four requires knowing the words for these numbers. Imagine trying to tell the difference between seven apples and eight apples. The task becomes almost impossible if you can’t count them—and you can’t count them if you never learn that “seven” is followed by “eight.” As a result of this language-number interdependency, many deaf children in industrialized societies fall behind in math, precisely because they did not learn to count early on.1<BLOCKQUOTE>Without language, we cannot plan, cannot communicate, cannot think.

Why did your friend go inside the house just now? Understanding social situations requires inferring what the people around you are thinking.

However, children with delayed language access have trouble imagining the mental state of other people.2 Moreover, brain regions involved in inferring others’ thoughts work differently in such children: They are active during all kinds of social situations, unable to properly distinguish scenarios that require mentalizing from those that do not.3 Theory of mind, therefore, is a prime example of a non-linguistic process that suffers if linguistic input is delayed.So far, the evidence we have seen does suggest that “the limits of my language mean the limits of my world.” However, what happens if language disappears once the mind is fully developed?

You look around the room, but no words come to mind to describe the objects you see. You’re starting to plan out your day, but no half-formed phrases rush through your mind. You unlock your smartphone, but, instead of text, you see a sea of squiggles.

In your case, let’s say that a dozen doctors examined you and said (or, you think they said) that nothing can be done. If the limits of your language mean the limits of your world, should you conclude the way you experience the world is now fundamentally limited?
