Paradox of Pinocchio

If Pinocchio were to say the statement “My nose will grow now,” it would create a paradox.

Perhaps you haven’t heard of this before, but if Pinocchio were to say the phrase “My nose will grow now,” it would result in a paradox…

Allow me to explain…

We all know that Pinocchio’s nose grows when he tells a lie.

If he were to say “my nose will grow now” and his nose actually did grow, that would mean he wasn’t lying. However, if he wasn’t lying, his nose wouldn’t grow.

But then his statement would be a lie… so his nose would grow… but then the statement wouldn’t be a lie… so his nose wouldn’t grow… you get the idea.

In essence, for Pinocchio’s statement to not be a lie, his nose would have to grow. However, his nose can’t grow, or else the statement would be a lie.

Origins of the Paradox of Pinocchio

The Paradox of Pinocchio was first conceived in February 2001 by an 11-year-old named Veronique Eldridge-Smith, the daughter of Peter Eldridge-Smith, who specializes in the philosophy of logic.

The article was initially published in the journal Analysis, and the Paradox of Pinocchio quickly gained popularity on the internet.

“My nose will grow now” is the only paradox that Pinocchio can create by saying something.

For instance, if he were to say “I will sneeze now” and he didn’t, that would be a lie, and his nose would grow.

Hopefully, this makes sense to you, and if you have any more crazy paradoxes, let us know!


1. What is Pinocchio’s Paradox?

Pinocchio’s Paradox is a philosophical paradox that arises when Pinocchio, the fictional character from the children’s story, is asked the question, “My nose will grow now, is that true?” The paradox arises because if Pinocchio’s nose grows, then he has told a lie and therefore his nose should not grow. But if his nose doesn’t grow, then he has told the truth and his nose should grow. This creates a contradiction, and thus the paradox.
