Glazer, Nathan. "Revolutionism and the Jews: 3 - The Role of the Intellectual." Commentary, September, 1971.
Excerpt: It is notoriously difficult to frame a definition of “intellectuals” that will serve for all times and all issues, but let me suggest a working one: Intellectuals are people who make a living from ideas, and are in varying degrees directly influenced by ideas. Thus they live off ideas and they live for ideas. Politically, as we know, the intellectuals have in general been critical of established institutions and values, sometimes from the Right, much more often from the Left.
