Gabrielle Jackson (Harvard) presents a complete account of Merleau-Ponty's notion of motor-intentionality, as it appears in Phenomenology of Perception. In order to do this, she first poses a problem for cognitive science, concerning what we can learn about the normal from the pathological.

Merleau-Ponty believed that his neuropathological patient's intentions and bodily movements had become uncoupled, and concluded that such a disunity could not be the model that all, or even most, actions follow. Instead, his motor-intentional theory of action asserted that, for the vast majority of actions, intentions and bodily movements enjoy an inseparable unity.
