The entire foundation for the concept of wisdom is in knowing what you don’t know. It's wisdom that tells you, if you don't know how to fly a plane, stay the hell out of the cockpit.

While I can still have a conversation about what I think it would be like to be a pilot, I can't reasonably imagine it without having experienced operating a large vehicle, looking out a window at a horizon, and having the responsibility of not crashing.

I could imagine a far off planet, but to describe the colors of horsacs or the sounds the molfors make, I could only draw from those I'd seen and heard before.

Can I write what I do not know? Sure. ¥€|¤, for instance. Ask me what that is and I'll tell you, I have no clue, but writing means nothing without actually communicating with a reader, so to truly write, I cannot share words to which I do not know the meaning.
