William's Syndrome is a genetic disease caused by a change in a gene on chromosome 11, in which affected children are very low in general intelligence, but have a vivid, rich and loquacious addiction to using language. They chatter on, using long words, long sentences and elaborate syntax. They have a heightened ability to learn language but at expense of sense. They are severely mentally retarded.
Their existence seems to undermine the notion that reason is a form of silent language.

None of this is made up, i swear. (almost) Scout's honor.
The syndrome thingy explains SO many things, it gives me a headrush.
