Embodied

Embodied intelligence is the knowledge that lives in the body. It is the carpenter who feels when the wood is about to split, the surgeon whose hands know tissue tension before conscious thought arrives, the dancer who understands momentum through muscle rather than equation.

AI has no body. It has no proprioception, no fatigue, no spatial experience of being in a place rather than processing data about a place. The most sophisticated robotics systems simulate embodiment; they do not possess it. The difference matters because embodied knowledge is not a degraded form of propositional knowledge — it is a different kind of knowledge entirely.

Situatedness — being physically present in an environment that pushes back — shapes cognition in ways that disembodied processing cannot replicate. You cannot understand heat from a dataset of temperatures. You understand heat because it has burned you.

Articles in this tier explore physical situatedness, sensorimotor grounding, and the forms of intelligence that emerge only from having a body in a world.
