The paradox of the Ship of Theseus describes a ship that can sail on the sea for hundreds of years. Once a piece of wood is rotted, it will be replaced until all the functional components are not the first ones. The question is whether the ship that was ultimately produced is still the original Ship of Theseus or an entirely different ship. If it is not the original ship, then when is it no longer the original ship? Philosophers Thomas Hobbes later extended it as if you use the old parts from the Ship of Theseus to rebuild a new boat, which of the two ships is the true Ship of Theseus?

One netizen claimed to be “das” answered the question and his answer was welcomed by netizens. He believed that the basis to determine a thing being itself is not the element that makes it up, but the internal structure which is the relationship between elements, and the temporal continuity of this matter. There is an identical principle in quantum mechanics, which tells us that particles of the same kind are inherently indistinguishable. The elements that make up your body have been replaced, but the particles of the same type are exactly the same and there is no difference in the nature. Replace this hydrogen atom in your body with that hydrogen atom, and your body's nature does not change. But if we break up a car into pieces and use it to make a metal statue, although its composition has not changed and it has continuity in time and space, its structure has completely changed. We cannot say that the statue is the original car. They do not have the same identity.

The second standard to judge identity is the continuity in space and time. If the two buildings have exactly the same structure, they are still two things because they are at different locations in space and do not have continuity in space and time.
This interpretation of das conforms to the idea of structuralist systems theory, and the basis for deter- mining identity is the structural feature, and the continuity of space-time is also the structural feature, because structure is the spatial positional relationship between things and components of things. The first part of the Taiji Evolutionism is System Theory of Structuralism, it states that structure is the essence of things, structure determines functions, and the essence of time, information, consciousness, and social relations are structures. However, this structuralist understanding is not the final answer to identity. Identity is an idea, which is the same as all other attributes of things.

There was a college students in philosophy department who returned to his rural hometown on vacation. The villagers all came to see him and felt that it was not easy for the village to produce a university student studying philosophy. Someone asked: “What did you learn?” The college student said, “Philosophy is about abstract things. For example, at the table, you see a chicken, but I see two chickens, a concrete chicken and an abstract chicken.” The villagers laughed aloud, the philosophy is all about this! The brother of the college student fel
