Metatheory
Typology
According to George Rizter, from the Wikipedia:
"Metatheory can be defined as the attainment of a deeper understanding of theory, the creation of new theory, and the creation of an overarching theoretical perspective. There are three types of metatheorizing: Mu, Mp, and Mo. Through the application of the three subsets of metatheory, Ritzer argues that the field of sociology can create a stronger foundation, experience "rapid and dramatic growth", and generally increase not only the knowledge of metatheory but social theory in general.[39]
The first category of metatheory (Mu), aims at being a means of attaining a deeper understanding of theory. Within the greater category of Mu, Ritzer establishes four other subsets: internal-intellectual, internal-social, external-intellectual, and external-social. The internal-intellectual sector of Mu identifies the "schools of thought" and the structure of current sociologists and social theories. The internal-social subtype identifies connections between sociologists and connections between sociologists and society. The last two subsets of Mu are looking more at the macrolevel of sociology than the other two subsets. The third subtype of Mu is the external-intellectual view of sociology; it looks at different studies and their concepts, tools, and ideas in order to apply these aspects to sociology. The fourth, and final, subset is external-social where the impact of social theory in a larger societal setting is studied.[39]
The second (Mp), aims at being a prelude to theory development. New social theory is created due to the complex study and interpretation of other sociologists. For example, Karl Marx's theories are based on Hegel's theories. The theories of the American sociologist, Talcott Parsons, are based on the theories of Émile Durkheim, Max Weber, Vilfredo Pareto, and Alfred Marshall.[39]
The last (Mo), aims at being a source of perspectives that overarch sociological theory.[39] Influenced by Thomas Kuhn’s The Structure of Scientific Revolutions (1962), Ritzer has long advocated the view that social theory is improved by systematic, comparative and reflexive attention to implicit conceptual structures and oft-hidden assumptions.[40]
Key works include Sociology: A Multiple Paradigm Science (1975), Toward an Integrated Sociological Paradigm (1981), Metatheorizing in Sociology (1991), and Explorations in Social Theory: From Metatheorizing to Rationalization (2001). See also Ritzer’s edited Metatheorizing (1992)."
