The structure of our concepts: A critical assessment of Conceptual Metaphor Theory as a theory of concepts

Abstract

Abstract George Lakoff and Mark Johnson’s Conceptual Metaphor Theory is by and large a theory of what (abstract) concepts are, how they are structured, and how this structure is acquired — i.e., by mapping of structure from one more concrete or sensory-motor specific domain to another more abstract domain. Conceptual metaphors therefore rest on “cross-domain mappings.” The claims to the effect that our abstract concepts are metaphorically structured and that cross-domain mappings constitute one of the fundamental cognitive meaning-making processes are empirical and can therefore be put to the test. In this paper, I will critically assess Conceptual Metaphor Theory as a theory of concepts in light of recent experimental findings. Many such findings provide evidence for the psychological reality of cross-domain mappings, i.e., that structure activated in one domain actually can perform cognitive tasks carried out in another domain. They do not, however, support the claim that the structure of our (abstract) concepts is still metaphorical, as Lakoff and Johnson claim — that is to say, that our mind actually does perform cross-domain mappings when we process conventional conceptual metaphors such as “Death is Rest” or “Love is a Journey.” Two conclusions can be drawn from this: (1) it is necessary to distinguish between cross-domain mappings (which are psychologically real) and the metaphoric structure of our concepts (which is not, in the sense that such concepts do not any longer activate cross-domain mappings when processed); (2) Conceptual Metaphor Theory is not an adequate theory of concepts. I will therefore sketch another more viable theory of concepts where the structure of our concepts is defined as the full ecology of their situations of use, which includes the kind of situations (objects, agents, interactions) they apply to and the kind of emotional, cognitive, bodily, and behavioral responses they elicit. On this view, the contents of our concepts are to be considered as vague predicates, with vague extensions, which take on a specific form in their situation of use.
