Proposition: Knowledge cannot be effectively shared only through spoken language.
As humans, we are constantly sharing and gaining knowledge through communicating with others. The question is if the knowledge we are communicating is the same knowledge gained by another. Is communication ever fully effective? By definition, effectiveness is decided by successfully producing a desired or intended result. I would argue that no type of communication is ever fully interpreted correctly.
A main form of communication is through spoken word. Languages vary all over the world, with roughly 6500 spoken in the world today. Mandarin Chinese is the most popular language in the world, spoken by about 1.21 billion people. This is one of the main flaws in communication. There is not one universal language that all humans use to speak with one another. Translations between languages are never 100% accurate, already altering the meaning of the shared knowledge.
Again as humans, we are all unique individuals with different experiences, personalitities, opinions, and values. Anything that we observe, hear, or feel is different when compared to another human. Therefore, when interpreting knowledge, it will not be exactly the same as the knowledge outputted to us.
Some may argue that there is a universal language between humans, but not through spoken word.
All humans smile, laugh, and cry, despite where they live in the world. Our facial expressions, tone of voice, and body language definitely aid in communication, but cannot be solely relied on for sharing knowledge. This can also be interpreted incorrectly, and some people cannot comprehend this universal language. Some humans suffer from social-emotional agnosia, which is the inability to interpret facial expressions, body language and voice intonation. This disorder usually effects people with autisim or schizophrenia, and limits social interaction.
- If many languages are spoken all over the world and can never be translated 100% correctly,
- And humans are all unique indivuduals that interpret knowledge in their own way,
- And the universal language of facial expressions cannot be comprehended by everyone,
- Then knowledge cannot be effectively shared only through spoken language
