"The tale becomes utopian only when the writer leaves the sphere of technical organization – when, for instance, he tries to make us believe that these cities are inhabited by better and more perfect human beings; that envy, murder, and adultery are unknown; that neither law nor a police force is needed. For in so doing he steps outside the technical scheme within which he is spinning his fantasies, and combines it in a utopian manner with something different and alien which can never be developed out of the scheme itself."
