> [!tldr] Is a ship that was rebuilt entirely, piece-by-piece, still the same ship? This is purely philosophy. But the Ship of Theseus is the name of the philosophical argument that a "ship" (or any other existential object) is not really just the sum of its parts. Every part of a ship can be replaced individually, such that no part of the original ship remains, but so long as that replacement is done gradually we tend *not* to think of it as a different ship. ## What is a Chair? The Ship of Theseus is an adjacent thought to "what is a chair"? I can't remember the exact location I first ran across the "what is a chair?" concept, but it's worth thinking about. - Is a chair legs and a seat? If that's the case, a horse with a saddle is a chair. - Is a chair simply something you sit on? If that's the case, the ground is a chair. When you start deconstructing a chair, at what point does it cease being "a chair". All I know is that [[This is not a chair]]. **** # More ## Source - various, including Wandavision, interestingly.
