Although it seems obvious the fact is that the progressive mechanization of the world makes it look more and more like a huge mechanism. The historian of technology Lewis Mumford showed us the importance held by the watch at the dawn of the technified Europe (Technics and Civilization, 1934). Since then the world resembles more and more a huge clock, in which the inertia of the bigger wheels forces the unrelenting movement of the entire system. With the distinctive feature that some of these wheels expand as living beings crushing between them the smaller ones.
