"If Pinocchio lies, then his nose grows."
Thus, as Pinocchio lies, it follows that his nose grows. We can formulate the following set of possibilities and, based on the premise, eliminate impossible cases:
- Pinocchio lies and his nose does not grow: this possibility is discarded because whenever he lies, his nose grows.
- Pinocchio lies and his nose grows: this possibility is discarded, because if he lied in the sentence "my nose will grow now," it means that his nose should not grow.
- Pinocchio tells the truth and his nose does not grow: this possibility is discarded, because if he told the truth in the sentence "my nose will grow now," it means that his nose should grow.
- Pinocchio tells the truth and his nose grows: nothing prevents such a possibility from occurring, based on the premise.
- Pinocchio's nose shrunk.
So the only viable possibility is that the sentence is true and that his nose grows.
