In order to enter a meaningful discussion of "truth value" we must define
a common basis for it for at least the set we are considering (English
sentences).

Since an infinite number of sentences can be formed with the syntactic
rules provided by the English language, yes, I'll deny that the
syntactically correct sentences of English are enumerable.  I don't,
however deny the existence of your particular sentence.
 
You've come no closer to defining "truth value."

Without interpretation, truth value (however you may wish to define it) is
meaningless.  Even with interpretation, truth value is, at best,
inconsistent between interpretations.

What is the truth value of the above sentence?

It was circular in that truth value seemed to be defined by you saying
that your sentence was on a list that your sentence was on.  It was so
obvious that even you pointed it out.
