An epistemological perspective rooted in social constructionism helps to temper
theoretical tendencies toward naive realism. All knowledge and all truths implicate
some kind of social agreement. It is through communication that ideas are accepted
or rejected; truth is not discovered or unearthed and cannot be determined in any
a priori way. Communication is involved when something is declared to be a fact,
in the interpretation of that fact, and also in how it is used to justify action. This
also extends to discourse communities that often try to deny that communication
plays a role – for instance, economics and branches of science dealing with objective
facts. Nevertheless, all types of knowledge must rest upon some kind of human
consensus and, thus, there is a need for communication
