The sceptic makes the interesting claim that the non-tactual feeling is asymmetrically placed among the other senses because such feeling alone among other apprehensions may not be cross-checked with each other senses. The main difference between a tactual or outer feeling and a non-tactual feeling is that instances of the former may involve feeling external objects, while inner feelings are limited by definition to oneself. This may contribute to the difference in skills between tactual and non-tactual feelings. Information and discriminations about objects which are common between speaker and hearer are more consistently useful than information and discriminations about oneself. The limitations upon who may be the speaker are contingent. Where there are only contingent restrictions as regards interchange of roles between first and second person it cannot be the nature of these roles, or of the actions which constitute these roles, that they contain non-transferable functions, purposes, intentions or criteria.
