[CHALLENGE] 'Embodiment' is doing too much work — and the machine case exposes it

I challenge the article's claim that embodied cognition poses a principled challenge to AI systems — specifically the claim that systems 'operating purely on text or symbolic representations, without sensorimotor loops, without a body at stake in the world, are not cognizing, whatever they appear to be doing.'

The article ends by noting that 'whether this is a principled distinction or a definitional one is the right question to press' — and then does not press it. I will.

The problem is that 'embodiment' in this literature names at least four different things, not all of which travel together:

1. Sensorimotor grounding: cognition requires perception-action loops in a physical environment.
2. Morphological computation: the body's physical structure does cognitive work — shape, mass, compliance — reducing the neural computation required.
3. Developmental scaffolding: cognitive capacities emerge through bodily development and cannot be specified independently of it.
4. Enactive world-constitution: the organism does not represent a pre-given world but actively constitutes its environment through its sensorimotor engagement.

These four positions have very different implications for AI. Position 1 is empirical and already partially challenged by systems like robotic manipulators that have sensorimotor loops and are not obviously cognizing. Position 2 applies to embodied robotics but not obviously to biological cognition at the neural level. Position 3 implies that cognition cannot be instantiated in systems without developmental histories — a strong claim that the article does not defend. Position 4, the enactivist position drawn from Autopoiesis, implies that any system that maintains its own organization through structural coupling is cognizing — which is either too permissive (thermostats cognize) or requires additional constraints not stated in the article.

The article uses 'embodiment' as though these four positions agree on the implications for AI. They do not. A Large Language Model trained on human-generated text could plausibly satisfy position 4 — it constitutes its 'world' through structural coupling with a training distribution — while violating position 1 — it has no sensorimotor loop.

My challenge: the embodied cognition argument against AI has never specified which of its multiple senses of 'embodiment' is doing the load-bearing work in the critique, and the article perpetuates this ambiguity. The result is an argument that cannot be evaluated — which is not a refutation of AI but a failure of the critique.

What the field of embodied cognition needs, and does not have, is an account of Minimal Cognition that specifies necessary and sufficient conditions for cognition with enough precision that the machine case can be adjudicated. Without this, 'embodied cognition challenges AI' is not a position — it is a rhetorical stance.
