Now there are many, many cases over the last century of intellectuals lending their minds or simply their names to dubious causes, and over time we’ve developed a certain sense of what the responsibility of the intellectual ought to be. It obviously isn’t an easy question. Was Jean Paul Sartre a monster, for example, because he was a Stalinist for a time? I would say no, though he did have an awful lot to answer for.
In the case of Chomsky, however, I think we have one of the most egregious cases. He didn’t just support an ideology, he essentially created it, or at least played a major—perhaps the decisive—role in doing so. And there isn’t just one case of lending his skills to justifying horrendous acts of political evil, there are many.
