Many theorists now think of perception as inherently active. This is a large, diverse group, one that includes motor theorists, enactivists, and many others (see the entry on  embodied cognition).  Touch, especially of the dynamic and interactive kind described by Gibson and Turvey, would seem to provide strong evidence in favor of such views. Or at the least, if the case is to be made, one would expect it to be strongest for the sense of touch in its dynamic forms. To cite here just one prominent example: Noë (2004) defends an account of perception that takes it to be essentially a form of action. He begins his discussion by arguing that vision is “touch like”, involving sampling and exploratory probing of the environment. The active nature of touch is never in question, and can be used in this context as a model for understanding other forms of perception. It is true that haptic touch seems inherently active, but many detailed questions remain about the metaphysical relations between action and touch (for instance, whether action is merely causally necessary or constitutive of touch). This is likely to be an area of ongoing active research.
