intensional knowledge and processing. The other towards 
day-to-day, heuristic intensional knowledge and processing. 
This notion of dual semantic processing modes arises from 
several sources. Putnam (1975) has established that a term 
can be used by people without them knowing the full 
extension or the correct intension of the term. For 
example, many people may use the word "gold" correctly, but 
only a few experts know the real extension and the correct 
intensional criteria for defining that extension. There is 
no reason to believe that other concepts, including 
"ownership", should be any different. Socio-linguistically 
we can function in two semantic modes, the more informal, 
casual way or the more formal exact way. Further, this 
implies that a linguistic division of labor is necessary for 
those "terms whose 'criteria' are known only to a substrate 
of the speakers who acquire the terms, and whose use by the 
other speakers depends upon a structured cooperation between 
them and the speakers of the relevant subsets" (Putnam, 
1975, pp. 146). With property, the experts probably are 
property lawyers and "structured cooperation" probably is 
legal proceed ings. 
This would be consistent with Thorngate's (1976, 1979) 
arguments that, generally, social cognitive processing 
capitalizes on the strengths of long term memory and takes 
advantage of heuristics, to avoid computational cognitive
