"All education starts with language."
Not all. Some animals teach their young by example. Humans also teach by example was well as with language.
Some might argue that language need not be vocal but simply a common frame of reference for the purposes of transmitting information.
@LenHazell53 that was the thought. Sign, written, spoken, visual representation. I guess that a visual representation isn't language. Would it be better to say "communication" instead? I still think it hits the mark well... starts with communication. I liked the way it sounded. Either way, hard to teach, or learn something without an appropriate way to communicate a new idea. And a new idea needs ways to be described.
@ownworstenemy "Communication" would be better, because it is hard to determine3 how much communication without spoken language is innate (instinctual or otherwise) and how much is learned.
