For [Jane Austen and the readers of Pride and Prejudice], as for Mr. Darcy, [Elizabeth Bennett's] solitary walks express the independence that literally takes the heroine out of the social sphere of the houses and their inhabitants, into a larger, lonelier world where she is free to think: walking articulates both physical and mental freedom.

Cities have always offered anonymity, variety, and conjunction, qualities best basked in by walking: one does not have to go into the bakery or the fortune-teller's, only to know that one might. A city always contains more than any inhabitant can know, and a great city always makes the unknown and the possible spurs to the imagination.

One lives in the whole world rather than in interiors built up against it.
