Full Idea
You should no more attribute understanding of Chinese to this one part of the system than you should ascribe the properties of the entire British Empire to Queen Victoria. This is the fallacy of division.
Gist of Idea
Searle is guilty of the fallacy of division - attributing a property of the whole to a part

A Reaction
This very nicely pinpoints what is wrong with the Chinese Room argument (nice analogy, too). If you carefully introspect what is involved when you 'understand' something, it is immensely complex, though it feels instant and simple.
