> Give me a precise definition for what you mean by "understanding" and I'll dismantle the Chinese Room for you.
You probably can't define "chair" in an exact enough sense. It would merely show the shortcoming of the definition rather than refuting the Chinese Room.
> a system not capable of intent
If I now would require a definition of "intent" I would be just as childish.
> That does not hold.
First, the system isn't stateless. It has the operator who has to remember what has happened before in order to come up with a correct translation.
Second, your argument implies that understanding requires intent. That alone is a tall order to prove. But it's the point of the Chinese Room: the mechanism doesn't understand, doesn't have intent, nothing. Yet it performs exactly as an intelligent, understanding, intentional translator. So would you not agree with the conclusion: you can't judge intent by only looking at I/O behavior?
Note that Searle (probably, this is just my understanding) doesn't mean that the Room is useless or "dumb" (in most senses of the word).
