Great find from Ben Smith, who links to Whittaker Chambers's brutal takedown of Ayn Rand's 'Atlas Shrugged' in National Review in 1957 and notes that Chambers could really write:

Out of a lifetime of reading, I can recall no other book in which a tone of overriding arrogance was so implacably sustained. Its shrillness is without reprieve. Its dogmatism is without appeal. In addition, the mind which finds this tone natural to it shares other characteristics of its type. 1) It consistently mistakes raw force for strength, and the rawer the force, the more reverent the posture of the mind before it. 2) It supposes itself to be the bringer of a final revelation. Therefore, resistance to the Message cannot be tolerated because disagreement can never be merely honest, prudent, or just humanly fallible. Dissent from revelation so final (because, the author would say, so reasonable) can only be willfully wicked. There are ways of dealing with such wickedness, and, in fact, right reason itself enjoins them. From almost any page of Atlas Shrugged, a voice can be heard, from painful necessity, commanding: "To a gas chamber -- go!"
