The relation between touch and agency reveals more interesting areas for further investigation. In particular, it seems plausible that the sense of touch has a closer connection to our agential actions. This is partially a result of the fact that touch seems to require active exploratory movements, and these movements are often guided and voluntary. Given these close connections, it is probably not surprising that touch has such a close connection to agency.  One could even use of this close connection between touch and agency to address epistemological problem of perception (see Smith (2002), and the entry on the  problem of perception). When we press against a solid object, the resistance to our agential act of pressing gives our experience a more solid epistemic foundation than what we experience through the other sensory modalities. Only in touch do we seem to come into direct contact with reality, a reality that actively resists our voluntary actions.
