Why is the statement 'This sentence is false' so confusing?
In the logical sense, sentences must be either true or false and not both. "This sentence is false" cannot be true because that would mean that it is false, and it cannot be both. It also cannot be false because that would mean that it is true, and it cannot be both. Therefore, if it is true or false, then it is both true and false. Therefore it is either neither true nor false or both true and false; therefore, in the logical sense, it is not a sentence. However, it says it is a sentence; therefore, it is lying; therefore, it is false.
This statement is false brain teaser?
Let us consider "This statement is false." This quotation could also be read as "This, which is a statement, is false," which could by extent be read as "This is a statement and it is false." Let's call this quotation P. The statement that P is a statement will be called Q. If S, then R and S equals R; therefore, if Q, then P equals not-P (since it equals Q and not-P). Since P cannot equal not-P, we know that Q is false. Since Q is false, P is not a statement. Since P says that it is a statement, which is false, P itself is false. Note that being false does not make P a statement; all things that are statements are true or false, but it is not necessarily true that all things that are true or false are statements. In summary: "this statement is false" is false because it says it's a statement but it isn't.

The answer depends on your definition of statement, It is a grammatical correct English declarative sentence which may be a statement by one definition. However, in logic, a statement is defined to be a sentence that is either true or false but not both. This sentence is not a statement by this definition.It is neither true nor false, because if is true, since it says it is false, it is false. If it is false. then is true since that is exactly what it says.Please see the related question for more about this famous paradox.
Paradox meaning of "Everything I say is a lie"?
The statement is paradoxical because it can not be true. If everything that you said was really a lie, then you would not be able to say, "Everything I say is a lie," because that would be a true statement. Therefore it can never be truthfully said. You could say, "everything that I say is a lie," and be lying, but that statement is still false at that point because you're lying while saying it, which means that you can tell the truth.
