The ideas included in this brief book continue, deepen, and also renew the analyses of the Decline of the West, the major work of Oswald Spengler. The central question that occupies this German philosopher is the emergence and multiple consequences of the dominance of industrial technique: on a social, economic, and spiritual level, within the very declining West; on a geopolitical level, regarding the relations of the West with non-Western peoples; finally, on an ecological level, as the author analyzes how the power and predatory and expansive nature of Western technique are used by humanity as the highest and most effective weapon in their Promethean struggle against Nature.
