as opposed to, national integration. His early work on education contributed to his creation of critical race theory, alongside Kimberlé Crenshaw, Alan Freeman, Cheryl Harris, Patricia J. Williams, Charles R. Lawrence, Mari Matsuda, and Richard Delgado. In the 1970s, Bell and these other legal scholars began using the phrase "critical race theory" (CRT) as a takeoff on critical legal studies, a branch of legal scholarship that challenges the validity of concepts such as rationality, objective truth, and judicial neutrality. Critical legal theory was itself a takeoff on critical theory, a philosophical framework with roots in Marxist thought. Bell continued writing about critical race theory after accepting a teaching position at Harvard University. He worked alongside lawyers, activists, and legal scholars across the country. Much of his legal scholarship was influenced by his experience both as a black man and as a civil rights attorney. Writing in a narrative style, Bell contributed to the intellectual discussions on race. According to Bell, his purpose in writing was to examine the racial issues within the context of their economic and social, and political dimensions from a legal standpoint. In addition to this, Bell's critical race theory was eventually branched off into more theories, describing the hardships of other groups, such as AsianCrit (Asian), FemCrit (Women), LatCrit (Latino), TribalCrit (American Indian), and WhiteCrit (White). His theories were based on the following propositions: racism is ordinary, not aberrational. white-over-color ascendancy serves important purposes, both psychic and material, for the dominant group. ("social construction" thesis) race and races are products of social thought and relations. dominant society racializes different minority groups at different times, in response to shifting needs such as the labor market. "intersectionality and anti-essentialism" thesis. No person has a single, easily stated, unitary identity. Everyone has potentially conflicting, overlapping identities, loyalties, and allegiances. For example, a person who has parents with different religious views, political views, ethnicity, etc. "voice-of-color" thesis) because of different histories and experiences to those of white counterparts, matters that the white people are unlikely to know must be communicated to them by the racialized minorities. CRT has also led to the study of microaggressions, paradigmatic kinship, the historical origins and shifting paradigmatic vision of CRT, and how in-depth legal studies show law serves the interests of the powerful groups in society. Microaggressions are subtle insults (verbal, nonverbal, and/or visual) directed toward people of color, often automatically or unconsciously. For
