In philosophy, postpositivism is, as the prefix indicates, a metatheoretical stance following positivism. One of the main
supporters of positivism was Sir Karl R. Popper. Other mentioned in connection with postpositivism are John Dewey and Nicholas Rescher.
In the Social Sciences, Postpositivism is used to refer to a group within political theory (mostly comprised of feminists and postmodernists) who do not believe it is possible to view politics from an objective point of view. They also value language, speech, and culture when dealing with rational political decisions. It encompasses the group of political theorists who believe that theory both shapes reality and follows it. It is the opposite of Positivism
