It is an automaton. It automatically produces categories of the real. The precise mechanism inside the tiny shell is a remarkable system of gears and jewels that produces a response we call automatic insofar as it is without interference, except that we may have to wind it. A bird is not lost to the automaton. Nothing in nature is taken away.
Nothing is subsumed.
The automaton must follow the laws of nature. It is a victim of the very same things as all birds. It will eventually stop. It will rust and its metal will corrode and their molecular structure will break down. The automaton emphasizes the real by its mimicry.
