The Ship of Theseus, also known as Theseus’s paradox. Sometimes also known as the Axe paradox
The axe version is that if you are given an Axe and replace the wooden handle is it the same axe? What if you then replace the blade? How many times can you repeat this process before the Axe is no longer the same Axe?
The cool thing about this is that your entire body is made up of a different set of cells every 7 years or so (as cells die). So can you really say you’re the same person you were 7 years ago?
