Sometimes ideas are difficult to grasp. At other times they might go right over my head or be simply too hard, too thorny, too slippery, or too big to get my head around. These choices of terms that we use to describe the experience of difficulty we face when confronted by such ideas is suggested of a particular kind of relationship, or rather lack of relationship, between these ideas and ourselves.
The philosopher J.J. Gibson (1977, 1979) proposed a theory of perception (and by extension, cognition) in which the repertory of basic elements that we draw upon when visual engaging with the world is not the abstract logical world of geometrical shapes and forms but the potential for physical action that objects and spaces presented. When we see a table, for example, we do not see a set of connected rectangular solids which we mentally assemble and subsequently recognise as a piece of furniture that we might then choose to lay for dinner. Rather, Gibson would claim, we percieve primarily a ’supportable surface’ which only later might we decompose into its logical constituent parts. He termed these primary perceptual qualities ‘affordances’ and the objects and spaces to which we relate ‘affordance structures’. Clearly, the affordance of an object is dependent largely on the form of the living body and on the needs, habits, and preferences of the entity possessing that body. An object which is recognisable as a ’supportable surface’ by one entity, and might therefore be subsequently thought of as a table, might not afford the possibility of that kind of use by a differently-bodied entity, and cannot be recognised in the same way. (Some artworks play with these affordance differences to generate specific effects, for example, the work of Claus Oldenberg.)
Recognition therefore, at its most basic level, is a function of seeing the use of an object or space, and is an embodied, felt sense. If we return to the difficulty associated with trying to grasp ideas which are too hard, or trying to get our head around theories which are too deep etc. one possible interpretation for what is going on in those moments is that the difficulty is one not of intelligence or concentration but of perception. In order to recognise an object in real space one needs to imagine physicaly engaging with it, one needs to imagine this protrusion as a handle and this surface as supportable. Similarly, in the theoretical, metaphorical space of ideas, one needs to be able to imaginatively perceive the affordances of those ideas. One needs to be able to imagine holding firmly to a conveniently placed axiom as one steps across a syllogistic divide; narrowly avoiding a paradox by stepping back and containing the contradictory terms within a greater explanatory framework. It should be remembered that abstract thinking of the type that makes up all theoretical ideas, is always ultimately made up of embodied metaphor, because embodied metaphor is the language of cognition. So if complex ideas are to be grasped, stood under, held, or deconstructed, then we need to treat them as Gibsonian affordance structures.
