 Views on the nature of the mental in mental disorder come from both philosophical accounts and, implicitly, from cognitive psychology. In some philosophical accounts including those stemming from phenomenological traditions, the mental is distinguished by particular features: it bears a special relationship to conscious awareness, and to persons, for example, or may be taken to exhibit the distinctive “aboutness” or intentionality exclusive to mental attitudes (see  §5).  Some theorizing about meaning and language similarly emphasizes the reasons-responsiveness of all human thought and action, by which disorder can alone be explained and understood (Campbell 1999, 2001, 2013; Thornton 2007).
