 So far, the discussion of how to provide functional characterizations of individual mental states has been vague, and the examples avowedly simplistic. Is it possible to do better, and, if so, which version of functionalism is likely to have the greatest success? These questions will be the focus of this section, and separate treatment will be given to experiential (often called 'qualitative' or 'phenomenal') states, such as perceptions and bodily sensations, which have a distinctive qualitative character or “feel”, and intentional states, such as thoughts, beliefs, and desires, which purport to represent the world in various ways To be sure, there is increasing consensus that experiential states have representational contents and intentional states have qualitative character and thus that these two groups may not be mutually exclusive (see Horgan and Tienson, 2002). Nonetheless I will discuss them separately to focus on what all agree to be the distinctive features of each.
