chinese room
Thought experiment.
Imagine a person in a room with no knowledge of chinese, but with a rulebook on converting characters. Anyone outside would not be able to tell if they understand it.
This is used as an argument to show a computer program cannot have a mind.
I came across this while reading the Blindsight.
One interesting point is that any singular brain cell does not know a language, and could be said to just follow rules.
Does this make the human mind an illusion, and is similar to a program execution?
