I believe that language is for communicating the shared part of experience, or sometimes for creating the illusion of shared experience. Whatever is unique about a person's experience is going to get lost if you try to communicate it through language.

Ok, that's maybe a little too harsh-sounding. I think some people are relatively similar to each other, so that language can resonate rfairly well between them.

Still, I believe in tacit knowledge. And even if a skillful person can find words for some of it-- turn the bike wheel towards the direction you're falling is sound advice, but how would you convey exactly what it's like to be you riding a bike on a particular day, or what it's like to know how to ride a bike before you have words for it?
