Roark offers Toohey the ultimate put-down. He says: "But I don't think of you.”
Let’s imagine a scenario: Toohey gets transported to the fictional landscape of Atlas Shrugged, and he bumps into the novel’s hero, John Galt!
Toohey says: “Mr. Galt, we're alone here. Why don't you tell me what you think of me? In any words you wish. No one will hear us.”
How will Galt respond? I can’t imagine Galt saying, “But I don’t think of you,” to Toohey.
I have a feeling that Galt would be thinking of collectivist intellectuals like Toohey, because Galt is concerned with the social, political and economic situation in the country. Roark is a man with single purpose in life, architecture, but Galt is different, he is a multitasker—he is a talented scientist, and he has philosophical and political ambitions as well.
Galt does not aspire for political power but he wants to transform the character of society. He has a burning desire to create a society which is based on rational philosophical ideas.
In the area of science Galt succeeds in inventing an electric motor which produces limitless energy; in the area of politics he succeeds in stopping the motor of the world by persuading a significant number of talented industrialists, scientists and other professionals to go on strike.
