If we made up a word and we don't know what it means that means we "chose" not to know what it means. We made up the fact that we don't know. Ultimately all words in the english language are made up by humans.
The concept of consciousness itself doesn't exist. It exists because we made up a word for it. And the concept seems fuzzy because the word was made up and a fuzzy definition for it was chosen.
When you debate what "consciousness" is you are debating the definition of the word. This is not profound. The word is made up, the definition is arbitrarily chosen. You are debating a vocabulary problem what arbitrary definition should be attached to what arbitrary word. You are attempting to refine the fuzzy boundaries of a definition that we as humans already made fuzzy by our own choice.
Take a car and a boat. If I made some vehicle that can both drive on the road and sail on the water, is it a car or a boat? What you're not seeing is that it doesn't matter. It's just a vehicle, but the words "car" and "boat" lock you into this delusional debate that's attempting to classify the car-boat as one or the other. Do you understand? The concept of a car and a boat is poorly defined language influencing the way you think. Whether the vehicle is a car or a boat is meaningless. Same with consciousness.
If you still don't get it. How about this. I'll make up a new concept called Flurmo. Flurmo is something that is 30-40% a car and 60-70% a boat. Now when you debate whether the vehicle is a car or a boat you have to consider whether it's a flurmo as well. Car, boat or flurmo? It's easy to see how flurmo is made up, it's harder to see why car and boat are the SAME thing, they are also words that are made up. And so is consciousness. Consciousness is flurmo.
You stopped reading, because you made a false assumption. You then continued reading on my prompt and you came out with a conclusion based off of you misunderstanding the point. Hopefully you get what I'm saying now.
