In Through the Looking-Glass, Humpty Dumpty famously declares that words mean what he wants them to mean. I’ve known people to declare the same thing — that, for whatever reason, they can use their own meanings for words. (To be clear, Lewis Carroll was mocking the idea.)
While ideas matter more than the words used to express them, it’s a lot more challenging to communicate and discuss those ideas without a shared vocabulary. A common language that is rich and detailed makes the expression of ideas all the more precise and accurate.
This is why con artists prefer convoluted language: it’s a mask.
At one point in HBO’s Westworld (don’t worry, no spoilers) Robert Ford (Anthony Hopkins) gives a speech about stories, about the value of fiction. He references a belief that fiction elevates — or at least illuminates to good value — the human condition. The belief also holds that those who read a lot of fiction are in some sense “better” people.
The idea is controversial on several grounds. Firstly, it’s hard to define what makes people “better,” and you can’t measure or test what you can’t define. Secondly, even if “better” is defined, not everyone will agree with the definition. Thirdly, there’s a nature-nurture aspect that makes comparisons like this very hard to tease out of any data you can gather.
Maybe a place to start exploring the idea is to first define “fiction” and go from there…
