Soren Kierkegaard wants to tell us the truth about human existence. Trouble is, by his own account, everything he writes is a lie! He says as much in his books. So is what he has written true or false? If it’s true, then because it’s written, it’s false. If it’s false, then because he claims it in writing, it’s true. Either way, it’s both true and false. Such is the liar’s paradox.
