Critical theorist

While all philosopher do critical theory, not all critical theorists are philosophers. Socrates is reported in Plato's ouvre (c. 400 BC) to have defined philosophy as a method essentially striving for the Divine. According to this definition thus not everyone who does critical theory is a philosopher.
Critical Theory is a school of thought that stresses the reflective assessment and critique of society and culture by applying knowledge from the social sciences and the humanities. As a term, Critical Theory has two meanings with different origins and histories: the first originated in sociology and the second originated in literary criticism, whereby it is used and applied as an umbrella term that can describe a theory founded upon critique; thus, the theorist Max Horkheimer described a theory as critical insofar as it seeks "to liberate human beings from the circumstances that enslave them".[1]
