  Accordingly, Tye holds that anyone seeking to account for our ability to directly apprehend change by appealing to a unifying relationship between experiences is also misguided: there simply aren’t the token experiences there to be unified; a given period or stretch of consciousness is not composed of successive perceptions or experiences (203: 102). By way of an alternative he offers a one experience view of streams of consciousness: ‘The simplest hypothesis compatible with what is revealed by introspection is that, for each period of consciousness, there is only a single experience – an experience that represents everything experienced within the period of consciousness as a whole.’ (2003: 97) As for the manner in which succession itself is represented in the vehicles of phenomenal content, since introspection provides us with no access to these vehicles, Tye leaves the issue entirely open.
