I have trouble with you use of the word "represents" here.  It seems as
though you are using it in a manner such that the range of 'represents' is
the set of values {true, false}.  But then what word do we use for the
relationship between concepts and their reality ?  Please refer to Pierce's
diagram of  semiosis [1] .. well at least my version of it.   In other
words: 'Snow is white' represents that snow is white, it does not represent
'true'.  Please see diagram [2].
