What is the liar paradox?

The Liar Paradox is a self-referential statement, most famously "This sentence is false," that creates a logical contradiction: if the sentence is true, then what it says must be true, meaning it must be false; but if it's false, then what it says is false, meaning it must be true, leading to an endless loop where the statement can't be assigned a consistent truth value (true or false). This paradox challenges fundamental principles of logic and has been debated in philosophy for millennia, with no single agreed-upon solution.

What is an example of a liar paradox?

"I said in my alarm, Every man is a liar!" Is David telling the truth or is he lying?
