Re: Why Some Sentences Lack Truth Values

We will utilize the following three definitions.

Definition 1: A sentence is meaningful if and only if it is a picture
of a possible state of affairs.

Are you saying that every tautology is meaningful but its negation is
meaningless? This is different than what you've previously claimed, I
think. You've said

"There is a round square"

is meaningful and false, but

"There is a round square which is green."

is meaningless (right?).

In any case, "a picture of a possible state of affairs" is not very
illuminating and we seem to disagree on what it means. You say that
this test proves

"All round squares are green" (1)

is meaningless while

"Liberty is a fundamental value of democracy" (2)

is meaningful. This, despite the fact that others claim to know what
(1) means and the fact that you cannot come up with a picture for (2).

Thus, your definition doesn't seem to help understand what counts as
meaningful, since we don't know what counts as a picture of a possible
state of affairs.
