the theory has a number of implications for communication,for the representation of information,and for the basis and location of objective knowledge.With regard to communication,the theory imposes severe limits on the possibility of communicating meanings by linguistic or other means.Since the subjective meanings of individuals are uniquely constructed (with certain constraints accommodated in view of their genesis),it is clear that communication cannot be correctly described as the transfer of meanings.Signals can be transmitted and received,but it is impossible to match the meanings that the sender and recipient of the signals attach to them,or even talk of such a match.However,the ways in which linguistic competence is acquired,mean that a fit between sender and receiver meanings can be achieved and sustained,as evidenced by satisfactory participation in shared language games.This view of communication is fully consistent with the Communication Theory of Shannon (cited in Glasersfeld,1989).
