      The Pinocchio paradox arises when Pinocchio says: "My nose grows now", and is a version of the liar paradox.[1] In philosophy and logic, the liar paradox consists of the statement "This sentence is false." Any attempts to assign a classical binary truth value to this statement leads to a contradiction, or paradox. This occurs because if the statement "This sentence is false" is true, then it is false; this would mean that it is technically true, but also that it is false, and so on ad infinitum.
