Peace at the bottom

The doctor, too, seems to feel at home as if among family or a community when in the prison. He comments to Mr. Dorrit in one of the important quotes from "Little Dorrit" by Dickens that all he wants is “A little more elbow room,” and he expounds upon the benefits of their incarceration and the prison environment: “We are quiet here; we don’t get badgered here… It’s freedom, sir, it’s freedom!....Elsewhere, people are restless, worried, hurried about, anxious respecting one thing, anxious respecting another. Nothing of the kind here, sir” (Dickens 78-79).
Quite paradoxically, the doctor concludes by proclaiming, “[W]e have got to the bottom, we can’t fall, and what have we found? Peace” (Dickens 78-79).
Mr. Dorrit recognizes that he actually agrees with the doctor, acknowledging that while he was “[c]rushed at first by his imprisonment, he had soon found a dull relief in it” (Dickens 79).
