The "part-of" principle is fallacious
The internalization reply rest on a fallacious "part-of" principle, whereby, if you can't do X, no part of you can do X. Just because the man who has internalized the Chinese Room can't speak Chinese, it does not follow that no part of him can speak
Jack Copeland, 1993.
