How we cite our quotes: (Chapter. Paragraph)
Quote #1
A person is defined solely by the extent of his influence over other people, by the sphere of his interrelationships; and morality is an utterly meaningless term unless defined as the good one does to others, the fulfilling of one's function in the sociopolitical whole. (5.7)
This is how Dr. Haber understands the relationship between people and morality. You want to keep this in mind, because later in the novel he finds himself alone. If the only way a person has any worth is by their influence on other people, what happens to them when they are alone? Well, what happens to Dr. Haber is that he loses all sense of who he is. Maybe Dr. Haber should have found a different way to define himself?
Quote #2
He would stop her at any cost. He turned to her, ready for violence, his hands clenched. (5.53)
So here we realize that Dr. Haber will do anything he needs to in order to retain power. If it means killing a young lawyer, he's totally down with it. Well, that's one way to have influence over other people, we guess.
Quote #3
"Do you remember the Plague Years?" [...] "Yes, I do. [...] And my parents died that year. My wife the next year. My two sisters and their children after that. Everyone I knew." Haber spread out his hands. "Yes, I remember those years," he said heavily. (5.82)
George is asking Dr. Haber what he remembers about the plague years, and Haber responds with this quote. Notice that the doctor's entire family died, and he doesn't even shed a tear thinking about it. Why? Because he thinks that the death of everyone he knows is fine as long as it's for the greater good. What do you think about that? Is it right?
