Nothing to do with Dennett's "Quining Qualia" What about Hume's critique of causation? What about Kant's categories of thoughts? Or Berkeley's ideas? The empirical world has a consistent structure, whatever that means.
While I agree that a physical reality is the most compelling explanation for the empirical, it's not the only coherent one. And I don't agree that it's necessarily complete. As in, there could be more to the world than what physics, chemistry or biology posits, since those are explanations we come up with, not some God's eye view.
