Lewis Mumford Quote

Failing to divide its social chromosomes and split up into new cells, each bearing some portion of the original inheritance, the city continues to grow inorganically, indeed cancerously, by a continuous breaking down of old tissues, and an overgrowth of formless new tissue. Here the city has absorbed villages and little towns, reducing them to place names, like Manhattanville and Harlem in New York; there it has, more happily, left the organs of local government and the vestiges of an independent life, even assisted their revival, as in Chelsea and Kensington in London; but it has nevertheless enveloped those areas in its physical organization and built up the open land that once served to ensure their identity and integrity.
