Duality is a newly-discovered phenomenon.
The person who first discovered it in the event structure system was Jane Espenson, a graduate student at Berkeley who who stumbled upon it in the course ofher research on causation metaphors. Since Espenson's discovery, other extensive dualities have been found in the the English metaphor system. However, at present, it is not know just how extensive dualities are in English, or even whether they are all of the location-object type. At this point, I will leave off discussing the metaphor system of English, even though hundreds of other mappings have been described to date. The major point to take away from this discussion is that metaphor resides for the most part in this huge, highly structured, fixed system.
