Ok, imagine this - you have a vintage car. You replace all its parts through the years, it's still ur car, right? Then you use the old parts and build another car. Now you got two vintage cars or what? Originality ain't in the parts bro, it's in the story. For Theseus, the 'original' ship is the one with the most legit story, the rest is just a copy, even if it's made of the old parts.

How about we forget the material things for a sec and talk about identity in terms of function or purpose? Like, if a ship’s job is to sail and it's still sailing, then who cares about a few planks? But then, if all parts are replaced and the ship’s now in a museum, is its identify still intact if it lost its function? Purpose and function got to play a role in this puzzle.

If you think too hard about this, your head might just pop off and they'll have to replace it with someone else's. Then are you still you, or are you a whole new person? Don’t lose your head over it, eh?

Both ships are ships. Just call one Theseus 1 and the other Theseus 2 and be done with it.

The question hinges on what 'identity' means. If we define identity based on continuity and function, then the ship remains the same despite the replacement of its parts. However, from a materialist viewpoint that prioritizes substance, once the original planks are gone, the identity is lost. The reconstructed ship from old planks could arguably hold the original identity by virtue of original material. But personal identity is another beast. The crux there lies in psychological continuity - memories, consciousness. In people, unlike ships, the continuity of self is more abstract, tied to mind rather than matter.

Well, here's a scientific perspective for you. Consider the theory of quantum mechanics, where particles can be in a superposition of states until observed. Now, let's loosely apply this to the Ship of Theseus. Could it be that the ship too exists in a sort of philosophical superposition, both the same and not the same, until we 'observe' or define it with a criteria? Clearly, identity isn't as binary as we'd like it to be, it's more of a spectrum, possibly hinging on functionalism or informational patterns rather than a purely material makeup.

Idk man, the way I see it, everything's always changin', including us. Who's to say that 'original' thing ain't just a concept we're comfy with but doesn't really exist? Once those planks are off the ship, and you stick em somewhere else, they're part of something new. Both ships are Theseus' in a way, but also, neither of them are. 🤷‍♂️

Ship of Theseus always gets the brain juices flowing, doesn’t it? So my take is that what makes the 'original' ship isn’t just the planks but the structure, the form it had. Even if you replace all parts, as long as the structure remains same, it’s the ship. The old planks making a new one just gives us another ship, kind of like a twin, but not the Theseus. It’s all about continuity for me.
