“Humans have only been using reading and writing for a very short time in our history, so how else do we communicate?”
A written sentence has tremendous power, but in my opinion, only when meaning is explicit. Transliteracy, a view of literacy that encompasses all human sense must have the power to invoke imagination and notion (conceptual understanding) beyond the written word.
So why such dependence on the written word? Is the written word a domain of the elite? If a person miss-spells then that person is chastised, chastised from a very early age. Spelling tests are still used to determine levels of literacy, when words, we know are mere empty entities until associated with meaning.
Elitism and power? Language is a code, many sects, professions and organisations have their own code (language), asking the question, do humanity have too much invested in the written word to embrace transliteracy?
Furthermore, I now ask the question why am I using the written word here to express a notion of transliteracy?
