But objects aren't propositions. So alreadythere's a category error.I said what it means that an object is consistent. It means that it is identical to itself, or in other words, it has the properties it has. No square circle.Which, if I understand correctly, means every object is tautologically consistent.Every existent object is what it is. A square circle is not what it is, so it can't exist.You refer to the properties of the object. But those are mostly relational and we invent them, like my car that is insurable. They are no "of the object" per se. What else do we invent? The whole world around us?If you limit "the world" to it's description, yes.But only consistent descriptions correspond to the world, so in this sense the world is consistent.
I didn't say it wasn't. I was just pointing out that this is based on the premise that the world exists. So it is invalid to infer from "this world has a consistent description" that "all world's with consistent description exist".
And having a consistent description is not really that helpful. Before quantum mechanics everyone was sure that it was true of the world that nothing could be in two different places at the same time. It was/just/ logic.
