The author argues for a world not in which technology reigns, but rather in which it achieves a balance with nature. His ideal vision is what can be described as an “organic city,” where culture is not usurped by technological innovation but rather thrives with it.
Mumford contrasts these cities with those constructed around wars, tyrants, poverty, etc. However, the book is not an attack on the city, but rather an evaluation of its growth, how it came to be, and where it is heading, as evidenced by the final chapter “Retrospect and Prospect.”
Mumford notes apologetically in his preface that his “method demands personal experience and observation,” and that therefore he has “confined [him]self as far as possible to cities and regions [he is] acquainted with at first hand.” (source Wikipedia).
