What makes you you then? Why are you the same person you were 10 years ago and why does that exclude the copy?

If I took your biological brain and put in another person’s body, such that you had exactly the same memories, personality, likes and dislikes etc, would that still be you?

If I rearranged another person’s brain such that it had exactly your current state (ie same memories, personality as above) and in the process killed your original body, would that still be you?

At what point does it stop being you?

>the philosophy of Ship of theseus, is it still the same ship if you replace every part?

>Seems to be the same, clearly we think so

And what if I secretly take every original part and reconstruct the ship? Which is the original then?
