This chapter examines enactivist views, particularly Alva Noë's, which hold that spatial perception is constituted by the exercise of sensorimotor skills—a position called Sensorimotor Knowledge (SMK) views. The author discusses different versions of the view and offers an ability-based interpretation of the central notion of an 'implicit grasp' of sensorimotor correlations. Two main objections are considered.
The sense of touch, or haptic touch, is structured by an external spatial field called peripersonal space, which functions similarly to the visual field. Peripersonal space meets the necessary conditions for a spatial field, making it the external spatial field of haptic touch. This argument clarifies structural similarities and differences between the senses, focusing on how touch, like vision, operates within a spatial framework.
