The difference between word meaning and reference

HostIt's funny how we use words to point at things, but the words we choose seem to change how those things feel. I was thinking about how we can call a car a ride, a junker, or a set of wheels. Even if we're looking at the same hunk of metal, each name feels like it's doing something different. How can one thing have so many names that don't feel the same?

GuestThat gets at a big split in how words work. On one side, you have the thing itself, like that hunk of metal in the driveway. But on the other side, you have the way we think about it. For a long time, people saw a bright light in the sky just before the sun came up and they called it the morning star. Then they saw a bright light just after the sun set and called it the evening star. For many years, everyone thought they were two different lights. Then we found out they're both just the planet venus.

HostSo we have two names for one rock in space.

GuestAnd here is where it gets interesting. If I tell you that venus is venus, that's a pretty dull thing to say. It's like saying a cat is a cat. But if I told someone a long time ago that the morning star is the evening star, that would be a huge find. Even though both names point to the same thing, they mean different things to our minds. One name is tied to the dawn and the other is tied to the dusk. The meaning is like the path your mind takes to get to the object. If the paths are different, the words feel different, even if they end up at the same spot.

HostBut does that not just mean we're confused? If the truth is that they're the same thing, the names are just a mistake we made.

GuestNot really. It's how we handle our thoughts. Think about a story with a hero like superman. He's the same guy as clark kent. He has the same heart and the same hands. But if someone in the story says they love superman but they think clark is a bore, they're not being silly. They just don't know that both names point to the same person. To that person, the name superman means a hero who can fly. The name clark means a guy who works at a desk. The meaning is what we know about the thing, not just the thing itself. Our feelings and our plans are tied to the meaning.

HostWait, I don't buy that. If I see a rock falling toward my head, I don't need a name for it to know I should move.

GuestSure, for a falling rock, your body takes over. But most of life isn't about dodging rocks. It's about deciding what a thing is for. Is a rock a tool, or is it a piece of art? Is it a border for your land? The name you give it tells you what to do next. The meaning is the bridge between the thing on the ground and the action you take. It's why we can talk about things that aren't even there, like dragons or unicorns.

HostBecause we have the name even if we don't have the thing to point at.

GuestRight. A word like unicorn has a very strong meaning. We can all picture the horn and the white hair. The word gives us a clear path for our minds to follow. But when we get to the end of that path, there's no animal there. We can have words that have meaning but no object. That's how we can talk about our dreams, or the future, or things we just make up. We're playing with the handles even when there's no door to open.

HostIt's like we have a map of a city, and some of the streets on the map lead to real buildings, while others lead to empty lots.

GuestThat's a great way to see it. We spend most of our time looking at the map, not the buildings. We use those meanings to sort out our world and decide what matters. If we only looked at the things themselves, we would lose all the flavor of life. We would just be pointing at things in silence. The meaning is what lets us share how we see those things with each other. It shows the route we took to get there.

HostSo when we argue about what a word means, we're really arguing about which map to use.

GuestWe can all point at the same hunk of metal in the driveway, but one person sees a pile of junk while another sees their first car.

HostThat car hasn't changed, but the handle we use to grab it changes whether we want to fix it up or tow it away.
