Context

“—Do I think that the little villages have the conceit of the great towns?—I don't believe there is much difference. You know how they read Pope's line in the smallest town in our State of Massachusetts?—Well, they read it
«All are but parts of one stupendous Hull!»
—Every person's feelings have a front-door and a side-door by which they may be entered. The front-door is on the street. Some keep it always open; some keep it latched; some, locked; some, bolted,—with a chain that will let you peep in, but not get in; and some nail it up, so that nothing can pass its threshold.” source
