This chapter examines Noam Chomsky’s position as a public intellectual and his frequent usage of the trope of the doomsday clock. By discussing some ideas taken from cultural sociology, the author first contends that whatever the epistemic merits of their positions or the structure of the society they live in, intellectuals gain much of their public resonance from the performative strength of their interventions. One way in which they typically do that is by revising existing patterns of mythical thought like that of the apocalypse. In doing that, dramatic intellectuals provide the public with imageries of a mega-threat and construe similarly ambitious salvific solutions to the menace, hence abiding by a binary logic that sharply tells good from evil. With this in view, the chapter addresses how Chomsky has recently employed the metaphor of the doomsday clock to envision an existential mega-threat to humanity and has further identified the social actors who are to blame for the upcoming disaster.
