Newtonian gravity is a perfect example of two very different ontologies, very different sets of words about what the world is. In entonian mechanics, you have space and time separately, and thereis a field, the gravitational field, that pushes things around sos en language that you're speaking. And we're not comparing these two theories directly to each other. We're comparing both of them to our observations. So i think even though coon would have said they are in some sense incommensurable, it's not the perfect example of incommensurability, but it's in the same spirit.
