Finally there is a statement about what the Chinese Room proves that makes sense. I will agree that no physical entity in the Chinese Room understands, but I think it is because *physical entities* do not understand, *systems* do. Roger Penrose is simply wrong to say that is equivalent to postulating "mind-stuff". The systems reply takes it that a mind is a *pattern* produced by physical entities, and is not the entities themselves. This is no more dualism than is believing that sound is a vibration in physical matter, but is not itself matter, or that heat is a property of substances but is not itself a substance. When you say something like "I understand English", what is the "I" that understands? You (and Searle) seem to think it is a physical entity, a particular human body. I don't think that is right, at all. After all, as the old chestnut goes, you replace all the atoms in your body every seven years or so. Any mind that can remember back to your childhood cannot be completely associated with any particular physical entity. Daryl McCullough AKA Mr. Know-it-all
