Some context: Roberto Mangabeira Unger (; born 24 March 1947) is a philosopher and politician. He has developed his views and positions across many fields, including social, political, and economic theory. In legal theory, he is best known by his work in the 1970s and 80s while at Harvard Law School as part of the Critical Legal Studies movement, which is held to have helped disrupt the methodological consensus in American law schools. His political activity helped the transition to democracy in Brazil in the aftermath of the military regime, and culminated with his appointment as Brazil's Minister of Strategic Affairs in 2007 and again in 2015.
Unger's critique of economics begins with the identification of a key moment in economic history, when the analysis of production and exchange turned away from social theory and engaged in a quest for scientific objectivity. In Unger's analysis, classical economics focused on the causal relations among social activities, which were connected with the production and distribution of wealth. Classical economists asked questions about the true basis of value, activities that contributed to national wealth, systems of rights, or about the forms of government under which people grow rich. In the late-nineteenth century, in response to attacks from socialist ideas and debates about how society works, and as a means to escape the conundrums of value theory and to answer how values could become prices, marginalist economics arose. This movement in economics disengaged economics from prescriptive and normative commitments to withdraw the study of economies from debates about how society worked and what kind of society we wanted to live in. For Unger, this moment in the history of economics robbed it of any analytical or practical value.  Unger's critique of Marginalism begins with Walras' equilibrium theory, which attempted to achieve a certainty of economic analysis by putting aside normative controversies of social organization. Unger finds three weaknesses that crippled the theory: foremost, the theory claimed that equilibrium would be spontaneously generated in a market economy. In reality, a self-adjusting equilibrium fails to occur. Second, the theory puts forth a determinate image of the market. Historically, however, the market has been shown to be indeterminate with different market arrangements. Third, the polemical use of efficiency fails to account for the differences of distribution among individuals, classes, and generations.  The consequences of the marginalist movement were profound for the study of economics, Unger says. The most immediate problem is that under this generalizing tendency of economics, there is no means by which to incorporate empirical evidence and thus to re-imagine the world and develop new theories and new directions. In this way, the discipline is always self-referential and theoretical. Furthermore, the lack of a normative view of the world curtails the ability to propose anything more than a policy prescription, which by definition always assumes a given context. The discipline can only rationalize the world and support a status quo. Lastly, Unger finds that this turn in economics ended up universalizing debates in macroeconomics and leaving the discipline without any historical perspective. A consequence, for example, was that Keynes' solution to a particular historical crisis was turned into a general theory when it should only be understood as a response to a particular situation.

Some context: Browning was born as Charles Albert Browning, Jr., in Louisville, Kentucky, the second son of Charles Albert and Lydia Browning, and the nephew of baseball star Pete Browning. As a young boy, he put on amateur plays in his backyard. He was fascinated by the circus and carnival life, and at the age of 16 he ran away from his well-to-do family to become a performer. Changing his name to "Tod", he traveled extensively with sideshows, carnivals, and circuses.
Browning's feature film debut was Jim Bludso (1917), about a riverboat captain who sacrifices himself to save his passengers from a fire. It was well received.  Browning moved back to New York in 1917. He directed two films for Metro Studios, Peggy, the Will O' the Wisp and The Jury of Fate. Both starred Mabel Taliaferro, the latter in a dual role achieved with double exposure techniques that were groundbreaking for the time. He moved back to California in 1918 and produced two more films for Metro, The Eyes of Mystery and Revenge.  In the spring of 1918 he left Metro and joined Bluebird Productions, a subsidiary of Universal Pictures, where he met Irving Thalberg. Thalberg paired Browning with Lon Chaney for the first time for the film The Wicked Darling (1919), a melodrama in which Chaney played a thief who forces a poor girl (Priscilla Dean) from the slums into a life of crime and possibly prostitution. Browning and Chaney would ultimately make ten films together over the next decade.  The death of his father sent Browning into a depression that led to alcoholism. He was laid off by Universal and his wife left him. However, he recovered, reconciled with his wife, and got a one-picture contract with Goldwyn Pictures. The film he produced for Goldwyn, The Day of Faith, was a moderate success, putting his career back on track.  Thalberg reunited Browning with Lon Chaney for The Unholy Three (1925), the story of three circus performers who concoct a scheme to use disguises to con and steal jewels from rich people. Browning's circus experience shows in his sympathetic portrayal of the antiheroes. The film was a resounding success, so much so that it was later remade in 1930 as Lon Chaney's first (and only) talkie shortly before his death later that same year. Browning and Chaney embarked on a series of popular collaborations, including The Blackbird and The Road to Mandalay. The Unknown (1927), featuring Chaney as an armless knife thrower and Joan Crawford as his scantily clad carnival girl obsession, was originally titled Alonzo the Armless and could be considered a precursor to Freaks in that it concerns a love triangle involving a circus freak, a beauty, and a strongman. London After Midnight (1927) was Browning's first foray into the vampire genre and is a highly sought-after lost film which starred Chaney, Conrad Nagel, and Marceline Day. The last known print of London After Midnight was destroyed in an MGM studio fire in 1967. In 2002, a photographic reconstruction of London After Midnight was produced by Rick Schmidlin for Turner Classic Movies. Browning and Chaney's final collaboration was Where East is East (1929), of which only incomplete prints have survived. Browning's first talkie was The Thirteenth Chair (1929), which was also released as a silent and featured Bela Lugosi, who had a leading part as the uncanny inspector, Delzante, solving the mystery with the aid of the spirit medium. This film was directed shortly after Browning's vacation trip to Germany (arriving in the Port of New York, November 12, 1929).
