Social theory is an essential tool use by scholars in the analysis of society; through the use of theoretical frameworks social structures and phenomena are analyzed and placed in context within a particular school of thought. The field is interdisciplinary, drawing ideas from and contributing to such disciplines as anthropology, economics, history, human geography, literary theory, mass communications, philosophy, sociology, and theology. It is argued by many that the beginnings of social theory are difficult to pinpoint, many arguments return to Ancient Greece. Berch Berberlogu cites Plato, Socrates and Aristotle as some of the totemic figures amongst the Greek thinkers and traces their influence upon social theory throughout the enlightenment up to the late nineteenth and early twentieth century (Berberlogu 2005, p. xi). "Critical" social theories, such as neomarxist theories and feminist theories, argue that as theories are generally based on premises that entail normative positions, it is necessary to critique the ideological aspects of theories and related oppressive social relations.
