That's the whole point of quoting: quoting detaches the quoted text from its 
environment. Hence when unquoting, the environment of the original quotation 
is lost!
A horse is an animal and a "horse" is a word.
This is a statement, but "this" is a word that has nothing to do with the 
statement.
May be QQ Quin can help you (although his books are not easily read)
