Adorno was a leading member of the Frankfurt school, whose general stance he shared. His work belonged mainly to sociology, and was especially concerned with the contradictions and distortions imposed upon people by the post-Enlightenment world, with its sacrifice of life to instrumental, technological reasoning. Perhaps his best-known general work is The Authoritarian Personality (1950), describing the rigid, conformist personality-type, submissive to higher authority and bullying towards inferiors. Adorno’s celebration of paradox and ambiguity, as well as his pessimistic take on the Enlightenment, have been influential in post-modernist literary and cultural criticism. Other works include The Dialectic of Enlightenment (1941) and Negative Dialectics (1966).
