No, I said that because there is not path to p, it would need to be false, but that was based on the assumption that it could exist.

No, so True(L, p) is false
and thus ~True(L, p) is true.

Right, but that has nothing to do with the problem with True(L, p) being false, because, since p in L is ~True(L, p) so that make True(L, ~false) which is True(L, true) false, which is incorrrect.

right, by your definitions, True(L, p) is False, but that means that True(L, true) is false, so your system is broken.

You understand that True(English, "a fish") is false

  True(English, "This sentence is not true") is false
False(English, "This sentence is not true") is false
Is saying the same thing that you already know.

You get stuck when we formalize: "This sentence is not true"
as "p defined as ~True(L, p)", yet the formalized sentence has
the exact same semantics as the English one.

No, YOU get stuck when you can't figure out how to make True(L, p) with p defined in L as ~True(L, p) work. If it IS false, then the resulting comclusion is that True(L, true) is false, whicn means your system is broken.

   True(L, true) is false
False(L, true) is false
 This is the Truth Teller Paradox
and is rejected as not a truth bearer.
 

No True(L, true) must be TRUE by definiition. The value of the value true IS true.
true is the logic value of statement tmentrs.
"This statment is true" is the truth teller paradox, not the logic value true.
This goes back to the ambiguity of trying to discuss logic with words.
