Dialetheism is the view that some statements can be both true and false at the same time.[1] It is the opposite of the law of noncontradiction (LNC). Because of this dialetheism is completely opposite of what most philosophers call common sense.[1] Graham Priest defines it as believing there can be true contradictions.[2] Priest gives as an example the liar paradox (or liar's paradox).[3] If someone says "everything I say is a lie", then is the statement true or false? In this paradox it can be both.
