Do Chairs Exist?

[Angrboda]

Vulcan can answer for himself, but mereology is the philosophy concerning parts and wholes.  Mereological nihilism is the position that there are no parts and wholes in the world, that identifying something as a part and something else as a whole is just an arbitrary convention that we adopt which has no basis in the features of reality.  So yeah, you can say this is a chair, or that these are simples behaving chair-wise, but mereological nihilism is the position that there is no objective fact of the matter.

Right now, I’m sitting on a four-legged, cushioned object that keeps my bony arse from colliding with the floor. Conventionally, this is called ‘a chair’. In fact, this convention is so widespread (I’m tempted to use the term ‘universal’) I think it’s safe to state that an object with this form and function is objectively a chair.

In what way is it a chair independent of convention? If it's only a chair by convention, that's a subjective fact, not an objective one.
