The ship of theseus is a classic philisophical paradox that has stumped people
for thousands of years. The paradox goes as follows
They are both no longer the same ship. This stance is that they are no longer the same ship because of the one simple reason that they are each unique and differnet from the original. They have different parts they have gone through differnt things, and much more, the only thing they have in common is the name, and possibly the look. This is much like how you are not the you of yesterday, you have different experiences you know different things and have gone through and faced different challenges. If you go back in time, you can see you, have a conversation with you, and you guys may not agree with each other, even though you are "The Same person". I belive we as humans have a need to define things as something. Thats an apple, thats a tree, and thats the ship of theseus. But I belive this is a superfcial concept amongst humans.
The original ship is the same ship. This next stance is the belive that no matter how many parts have been replaced, it is still the original ship. It's the same situation with the human body, you replace dead cells everyday, you do not have any of your original cells from when you were a fetus in your mothers woumb. So what are you now no longer a you? If the "old you" killed somebody, are you not responsible for your actions, just because it was the you of yesterday who killed the guy? The answer is that you are the same you and the ship is the same ship. So, what if we took all the old parts and recreated the ship, would it be the original ship. No The parts do not define what is the ship, but it is the experiences of the ship, and what the ship not what the ship pyhsically is. What if you had a carbon copy of yourself infront of you. Are you no longer the you of today, do you not have your own thoughts and experiences. Just because PHYSICALLY it has the same cells and MENTALLY it has the same memories, does not change who you are.
