4. With regards to the formula 211 (McLaughlin (37)), it is interesting to note that T. Parsons (41), the eminent sociologist, demonstrated that institutionalized organiza tions also possess an increasing number of simultaneous variables with increasing degrees of complexity and essentially possessing a structure describable by 2n. Piaget (44) speaks of isomorphism in his important study of genetic epistemology where he draws a sort of parallel between ‘La pensée psychologique, la pensée sociologique et la logique’. The use of the 2n model in analysing processes in psychotherapy may prove to be a useful avenue to explore (Fried (21)).
