"Outline For A Viable Techno Sphere provides an informative condesnssed history of world culture, and examines all aspects of human life and society – psychological, physiological and anthropological. Sadler investigates man’s interaction with the biosphere – man’s place in the world – and anticipates further evolutionary developments. In his proposition for a “viable technosphere”, Sadler suggests a techno-culture formed in the light of a Darwinian, organic ideal, locating cities by means of systematic replacement, and integrating even one’s metaphysical existence with is exemplary criteria. Unlike most techno-visionaries, Sadler is also sensitive to the cultural repercussions of mans’ enlightenment, thus rendering his work the harbinger of a technological Renaissance. Functional aesthetics are given new resonance in his technological journey to the sublime. An ingeniously revealing read is set to stir the imagination with eye-opening insights and knowledge, and is a perfect addition to anyone’s collection."
