I came upon this idea of Theseus ship paradox recently.it made me think for a while and I came to a conclusion(which might not be right) that it is only a paradox when u look from 1 perspective. I use the word imagine a lot since I imagine a lot. Now imagine a person growing old and as he grow old. All the atoms in his body is being replaced. Now what makes a person a person is the memories he collected over time and so, his sense of being.so to me, if he retained all his memory he is he as a person but the body is not him when he was a child.his body he at the his current time. If his memory is retained partially of his childhood then he is not him as a whole when he was a child. Now the Theseus's boat after the travel is not his boat before the travel but to him it is to who he is now and the boat that was made from the scrap is his original boat before traveling but not the same boat after traveling. The scrap boat can also be his original boat if he deemed it worthy or if it is still in good condition. Lol. To understand this we need perspective what the original boat is and also time.please do comment if u see a plot hole and I will try to think more about it. Thank you Mr. James R for restoring my account or thank you miss James R. since he is in superposition right now to me. Jokes apart thank you.
