I like Locke but yeah, thinking’s progressed a bit. But he gives good food for thought. He works with the assumption that personalty doesn’t change when the body does, but the thing is, personality _does_ change as well. But whether it does or doesn’t, still a Ship of Theseus.
Thing is, Ship of Theseus isn’t really much of a paradox.
It’s just how it is. We’re both the same and different as we progress. The ship? Both same and different.
