… is from pages 153-154 of the 1975 HarperPerennial printing of the third (1950) edition of Joseph Schumpeter‘s 1942 volume, Capitalism, Socialism, and Democracy:
Labor never craved intellectual leadership but intellectuals invaded labor politics. They had an important contribution to make: they verbalized the movement, supplied theories and slogans for it – class war is an excellent example – made it conscious of itself and in doing so changed its meaning. In solving this task from their own standpoint, they naturally radicalized it, eventually imparting a revolutionary bias to the most bourgeois trade-union practices, a bias most of the non-intellectual leaders at first greatly resented…. Thus, though intellectuals have not created the labor movement, they have yet worked it up into something that differs substantially from what it would be without them.
