input: 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.
