An eminent and brilliant sociologist C. Wright Mills (1916-1962) was deeply concerned with the responsibilities of social scientists in the post-World War II (American) society. Therefore he advocated for engagement of intellectuals in public life in contrast to merely conducting distant observations. Mills’s research and writings had a significant impact on the Left and social movements of the 1960s.
“As a type of social man, the intellectual does not have any one political direction, but the work of any man of knowledge, if he is the genuine article, does have a distinct kind of political relevance: his politics, in the first instance, are the politics of truth, for his job is the maintenance of an adequate definition of reality. In so far as he is politically adroit, the main tenet of this politics is to find out as much of the truth as he can, and to tell it to the right people, at the right time, and in the right way. Or, stated negatively: to deny publicly what he knows to be false, whenever it appears in the assertions of no matter whom; and whether it be a direct lie or a lie by omission, whether it be by virtue of official secret or an honest error. The intellectual ought to be the moral conscience of his society at least with reference to the value of truth, for in the defining instance, that is his politics. And he ought also to be a man absorbed in the attempt to know what is real and unreal.” (1967: 611)
