By listening, speaking, seeing and reflecting on words made by the alphabets of a language - one experiences the World. How far is this correct? Can any one experience the World without a language? if yes to what extent, if no, why not?
Good question, sorry for bad English! I can't answer by all means but here are two points.
It is well known that children, that grow up without a language,
get a fatal lack of human consciousness.
Buddhists assert that adult human beigns may (and should) spend a long time without
words and estimations and this even improve their minds.
I practise Vipassana more than 15 years (being high-educated in theoretical physics)
and just confirm it.
How else would you experience the world? Is the color red itself the same as the word 'red'?
Of course we use words to describe our experience to others.
One could examine the world out there as logos by Christianity, a system of signs by semiotics in European philosohy as inspired by linguistics or information as modern physics - but this is language of an entirely different order and amongst themselves are not commensurate. In this sense no-one escapes language in their structuring of experience.
