Background: 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.
Context: The beginning of Unger's academic career began with the books Knowledge and Politics and Law in Modern Society, published in 1975 and 1976 respectively. These works led to the co-founding of Critical Legal Studies (CLS) with Duncan Kennedy and Morton Horwitz. The movement stirred up controversy in legal schools across America as it challenged standard legal scholarship and made radical proposals for legal education. By the early 1980s, the CLS movement touched off a heated internal debate at Harvard, pitting the CLS scholars against the older, more traditional scholars.  Throughout much of the 1980s, Unger worked on his magnum opus, Politics: A Work In Constructive Social Theory, a three volume work that assessed classical social theory and developed a political, social, and economic alternative. The series is based on the premise of society as an artifact, and rejects the necessity of certain institutional arrangements. Published in 1987, Politics was foremost a critique of contemporary social theory and politics; it developed a theory of structural and ideological change, and gave an alternative account of world history. By first attacking the idea that there is a necessary progression from one set of institutional arrangements to another, e.g. feudalism to capitalism, it then built an anti-necessitarian theory of social change, theorizing the transition from one set of institutional arrangements to another.  Unger devoted much of the following decades to further elaborating on the insights developed in Politics by working out the political and social alternatives. What Should Legal Analysis Become? (Verso, 1996) developed tools to reimagine the organization of social life. Democracy Realized: The Progressive Alternative (Verso, 1998) and What Should the Left Propose? (Verso, 2005) put forth alternative institutional proposals.
Question: Did the books help his career?
Answer: These works led to the co-founding of Critical Legal Studies (CLS) with Duncan Kennedy and Morton Horwitz.

Problem: Background: Oystein Aarseth (Norwegian: ['oystein 'os@t]; 22 March 1968 - 10 August 1993), better known by his stage name Euronymous, was a Norwegian guitarist. Euronymous was a founder of and central figure in the early Norwegian black metal scene. He was a co-founder of the Norwegian black metal band Mayhem. He was also founder and owner of the extreme metal record label Deathlike Silence Productions and record shop Helvete.
Context: Euronymous said that the term black metal can apply to any kind of metal, so long as it is "Satanic" and "heavy". He said "If a band cultivates and worships Satan, it's black metal" and that "In a way, it can be ordinary heavy metal or just noise. What's important is that it's Satanic; that's what makes it black metal". He rejected bands like Immortal being called black metal, "as they are not Satanists", but supported the band nonetheless. As noted earlier, bands who had LaVeyan beliefs were also rejected. When it was pointed out that Venom (the band who coined the term 'black metal') only used 'Satanism' as a gimmick, Euronymous said that he and the 'Black Circle' "choose to believe otherwise".  Likewise, Euronymous said that the term death metal can apply to any kind of metal, so long as the band "cultivates and worships death". Euronymous lamented the commercialization and loss of extremity within death metal. He said "Real Death Metal should be something normal people are afraid of, not something mothers can listen to" and "Death Metal is for brutal people who are capable of killing, it's not for idiotic children who want to have [a] funny hobby after school".  Like many others in the black metal scene, Euronymous originally believed that black metal should stay underground. However, he later changed his mind and said the idea should be got rid of. He believed that the idea of staying underground came from hardcore punk and said "Those who scream most about being in 'underground' is also often those who make so bad music that they don't have a chance to get big themselves". He added: "I wouldn't mind making DSP big and earn a million, as long as I don't change my ways of thinking and being [...] If there were one million black metal fans in the world, most of them would be jerks, but there would be really many true and brutal people as well. The bigger we get, the more we can manipulate people into thinking like us".
Question: What were his feelings for bands if they were not "Satanists"?
Answer:
Euronymous lamented the commercialization and loss of extremity within death metal.
