People can be annoying.
We don't have the statement so we don't have the answer.
If the statement is false, then "This statement is false", is a lie, making it "This statement is true." The statement is now true. But if the statement is true, then "This statement is false" is true, making the statement false. But if the statement is false, then "This statement is false", is a lie, making it "This statement is true." The statement is now true. But if the statement is true, then... It's one of the biggest paradoxes ever, just like saying, "I'm lying right now."
This is not a true statement.
It depends on whether the statement is subjective (opinion) or factual (verifiable). If a majority voices the same opinion (e.g. abortion is wrong), it doesn't necessarily make it true - or false. If the same people say the earth is flat however, that is not true.
Circular logic would be a statement or series of statements that are true because of another statement, which is true because of the first. For example, statement A is true because statement B is true. Statement B is true because statement A is true
If a statement is true, then its negation is false. The negation of a statement is essentially the opposite of that statement; it asserts that the original statement is not true. Therefore, if the original statement holds true, the negation cannot hold true simultaneously.
