 One other aspect of the Frege-Russell tradition of theorizing about content that impinges on the consciousness/intentionality connection is this. If content is identified with the sense or the truth-condition determiners of the expressions used in the object-clause reporting intentional states of mind, it will seem natural (even if it’s not inevitable) to suppose that possession of mental content requires the possession of conceptual capacities of the sort involved in linguistic understanding—“grasping senses”. Here, however, another issue rears its head: is there not perhaps a form of sensory intentionality that does not require anything as distinctively intellectual or conceptual as is needed for the grasping of linguistic senses or propositions? (This would be a kind of intentionality that could be had by the pre-linguistic (e.g., babies) or by non-linguistic creatures (e.g., dogs).) Advocates of varying versions of the idea that there is a distinctively “non-conceptual” kind of content include Bermúdez (1998), Crane (1992), Evans (1982), Kelly (2001), Peacocke (1992), and Tye (1995). For “conceptualist” voices of opposition to this trend, see Brewer (2005), McDowell (1994), and Speaks (2005). A deep difficulty in assessing these debates lies in getting an acceptable conception of concepts (and of concept possession) to work with (see Wright 2015).
