By the 1970s, Richard Sennett points out, anti-urban bias is not only observable in the right-wing, but on the revolutionary left, in the writings of Franz Fanon, and in Mao-Tse Tung and Fidel Castro's celebration of peasantry. Fanon held that "the necessity for bureacracy in a city an dthe anonymous character of human contacts were bound to destroy the feeling of closeness in men... these dense places would frighten men into pursuing safe routines where they knew they would not be overwhelmed. They would thus be pushed into private circles of security and eventually lost as revolutionaries" (Sennett, xv, Uses of Disorder - paraphrasing Fanon)

“Do you know, Watson,” said he, “that it is one of the curses of a mind with a turn like mine that I must look at everything with reference to my own special subject. You look at these scattered houses, and you are impressed by their beauty. I look at them, and the only thought which comes to me is a feeling of their isolation and of the impunity with which crime may be committed there.”

“Good heavens!” I cried. “Who would associate crime with these dear old homesteads?”

“It is my belief, Watson, founded upon my experience, that the lowest and vilest alleys in London do not present a more dreadful record of sin than does the smiling and beautiful countryside.”

“You horrify me!”

“But the reason is very obvious. The pressure of public opinion can do in the town what the law cannot accomplish. There is no lane so vile that the scream of a tortured child, or the thud of a drunkard’s blow, does not beget sympathy and indignation among the neighbours, and then the whole machinery of justice is ever so close that a word of complaint can set it going, and there is but a step between the crime and the dock. But look at these lonely houses, each in its own fields, filled for the most part with poor ignorant folk who know little of the law. Think of the deeds of hellish cruelty, the hidden wickedness which may go on, year in, year out, in such places, and none the wiser.”

Robert Smithson wrote an essay in the early 1970s entitled "Fredrick Law Olmsted's Dialectical Landscape," which considers the design of Central Park, it's naturalistic aesthetic lineage within 18th and 19th C. ideas about the picturesque, and contemporary uses of the park by hoods, homosexuals, graffiti writers and the like. Sounds very promising. Found here:
