This article points out that Michael Burawoy's call for a renewal of commitment to a public sociology has had a massive impact. Writing in the tradition of C. Wright Mills's clarion call, Burawoy seeks to defend the critical and reflexive role of the sociologist through his or her autonomous engagement in the public sphere of political decision. His argument has had a mixed reception in the United States. For the most part his views have been welcomed as re-emphasizing an important dimension of sociological activity that has, perhaps, been lost or submerged in the current political and financial climate of conservatism and retrenchment. Within the universities, many have found it easier to keep their heads down and get on with purely academic work, lest political involvement bring unwanted attention. Burawoy has been seen as re-asserting the political legitimacy of public participation. In some quarters, however, his views have met with a more negative reaction and have been seen as a scarcely concealed attempt to abandon impartiality and to advocate a leftist radicalism. This mixed reception was, perhaps, inevitable, given the political context in which Burawoy has intervened. He is, necessarily, critical of sociologists, other social scientists, the universities and the other institutions for which sociologists work, and also the wider structures of power in which these are enmeshed.
