It is tempting to try to assimilate whole cultures to the general outlook of individuals dropping to near zero. But sparsity conceals too many variables; better to stick to those on the diagram. There is ample material there for explaining the similarity between the world view of pygmies in the Ituri forest and that of certain Londoners deeply implicated in industrial society. First we should turn to the media of social relations. If the pattern of social relations put their stamp upon speech forms, as Bernstein’swork shows, they no doubt put a pattern upon non-verbal forms of communication as well. If the speech forms thus produced themselves control the kind’of social responses possible in a given social environment, we should expect the usage of the body for communication to exert a parallel constraint.
