Space, Motility, The Body

The title of one chapter in Merleau-Ponty's Phenomenology of Perception is 'The Spatiality of One's Own Body and Motility'. Despite the novelty of the study, the title expresses two of its flaws. First, it implies that a human body is distinct from its motions. Second, what distinguishes Motility from Mobility is that it is active, self-generating motion, and not merely passive moveability, which is what the latter connotes. But, to actively set oneself in motion requires Will, and Will entails an at least rudimentary mental component. Hence, Body alone is incapable of Motility. So, while Merleau-Ponty correctly attributes Spatiality to Motility, he compromises that attribution by deriving it from the Spatiality of inert, mindless Body, which reduces to the Spatiality of the sedentary Perception of Body, as the title of the whole book indeed articulates.
