If my friend is on a street corner with a life-like model of a dog and I drive past in my car so fast that I can't tell the difference between the fake dog and a real dog is there any point in me saying I saw a real or fake dog since, to me, the two are indistinguishable? The classes real dog and fake dog seem to combine to form the class dog-like object.
If this same analysis were applied to Searle's Chinese room then it seems pointless to say the room does or doesn't understand. If a person who is unaware of the room's setup (sort of like me in my car) goes up to the room and asks it questions then it provides answers that are consistent with the room understanding Chinese so from that persons point of view the room is just as understanding as any chinese person on the street. If we miniaturised the room and put it in someone's head and put a real Chinese speaker behind the Chinese room slot then the questioner will not be able to tell that any change has occurred.
