The Ship of Theseus paradox is one of the most famous paradoxes in all of philosophy. It is a thought experiment that raises the question of whether an object that has had all of its components replaced remains fundamentally the same object. Recently, I have heard about a potential solution to this paradox and it usually referred to as ‘Worm Theory’ and this is supposedly heavily related to the concept of four-dimensionalism. It seems that from my reading four-dimensionalism is also known as perduantism or worm theory.

Let me try to explain them:

In philosophy, four-dimensionalism (also known as the doctrine of temporal parts) is the ontological position that an object's persistence through time is like its extension through space. Thus, an object that exists in time has temporal parts in the various subregions of the total region of time it occupies, just like an object that exists in a region of space has at least one part in every subregion of that space. According to the worm theory, perduring objects are four–dimensional wholes occupying determinate regions of space–time and having temporal parts, or stages, each of them confined to a particular time. Simply, implicit assumption that worm theory therefore rejects is the notion that physical objects such as ships are merely three dimensional objects (where the three dimensions are spatial dimensions). Objects really do have four dimensions: three spatial and one temporal.

From all this we can see that its two main theses are: 1: Ordinary objects exist at more than one instant of time 2: Ordinary objects have temporal parts

So, is worm theory a good candidate to serve as a reasonable solution to the Ship of Theseus paradox? What are some good arguments in the theories favour? What are its benefits over other potential solutions to the Ship of Theseus also? Any recommendations would be greatly appreciated. Thanks everyone!
