The Chinese Room
Searle · Minds, Brains, and Programs · 1980
You are locked in a room. Through a slot, sheets covered in Chinese symbols are passed to you, symbols you do not understand in the slightest. But you have a thick rulebook, written in your own language, that tells you: "to this mark, reply with that one." You follow the rules, you pass sheets back, and outside a Chinese reader finds your answers flawless: to them, the room understands Chinese. You, though, have understood nothing. A machine that handles our words, a chatbot that answers so well, is it doing anything other than what you do in that room?
Is running a program, however flawless, enough to understand, or does handling symbols by their form alone stay blind to their meaning?
What it does in the debate
Objects to The substrate does not matterattacks the position
In the room the whole required organization is realized, and yet no one understands a word of Chinese: realizing the right program is therefore not enough to understand.
- In the room, everything functionalism asks for is assembled: the same inputs, the same intermediate states, the same outputs as a Chinese speaker. The organization is realized in full.
- Yet whoever applies the rules understands nothing: he does not even know what the sheets he hands back are about. He has the shape of the signs, never their meaning.
- If organization were what makes understanding, it would be there, present in the room. It is not.
Therefore So realizing the right organization is not enough to think: something is missing that the program, by construction, cannot supply.
