- 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.

- "The sky is green."
-
- What is the truth value of the above sentence?
-

- >has been pointed to.
-
- 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.
