proof:
P1. Assume the laws of logic are true.
P2. All propositions are either true or false (Law of Excluded Middle, P1).
P3. The proposition “This proposition is false” is neither true nor false.
P4. There exists some proposition that is neither true nor false (P3, Existential Generalization)
P5. It is not the case that all propositions are either true or false (P4, Change Quantifier)
P6. It both is and is not the case that all propositions are either true or false (P2, P5 Conjunction).
C. Therefore the laws of logic are not true (1-6 Indirect Proof)

> The proposition "This proposition is false."
Is not infact a proposition but a description of a proposition/a statement about one. An english teacher would tell you that you have not described the subject. What is the proposition you are talking about when you say it is false, what is "this proposition"? If you try to write it out, you will not be able to because you infact have no subject. So you are trying to apply logic to something that is incomplete and cannot make sense.
Its like saying "This thing is red. Prove that it isn't." We can't because you have not assigned a definition to "This thing."

But "This proposition is false" isn't a proposition. It's a a statement with no inherent truth value since it doesn't define what "this proposition" is.
