The appointment of Roberto Mangabeira Unger as Brazil's Minister of Strategic Affairs in 2007 and again in 2015 marked a dual career in academic philosophy and active national politics. Born in Rio de Janeiro in 1947, he established his scholarly reputation while operating within the Harvard University faculty and shaping social theory through extensive writing on law and institutions.
Early Education and Career
He entered Harvard Law School in 1969, earning his LLM before transitioning into the doctoral program. By age 23, he was teaching jurisprudence to first-year students. In 1976, at age 29, he secured a tenured position at Harvard Law School, becoming one of the youngest faculty members to reach that rank.

Take the IQ test →Critical Legal Studies
Unger rose to prominence during the 1970s following the release of his books Knowledge and Politics and Law in Modern Society. Alongside colleagues Duncan Kennedy and Morton Horwitz, he co-founded the Critical Legal Studies movement. This academic initiative disrupted established methodology within American law schools, initiating intense internal debates throughout the 1980s that pitted his cohort against traditionalist legal scholars.
Constructive Social Theory
His primary work, the three-volume series Politics: A Work in Constructive Social Theory, was published in 1987. The text challenged contemporary social theory by arguing that society is an artificial creation rather than a collection of necessary institutional arrangements. By rejecting the view that historical transitions, such as the shift from feudalism to capitalism, follow a predetermined path, he proposed an anti-necessitarian theory aimed at individual and collective empowerment.
Political Engagement
Outside of his academic duties, Unger has been a participant in Brazilian opposition politics. He served as a founding member of the Brazilian Democratic Movement Party and drafted its manifesto. He directed presidential campaigns for Leonel Brizola and Ciro Gomes and launched two exploratory bids for the Brazilian presidency. His political career included service in the second Luiz Inácio Lula da Silva administration.
