The 'world wars' and their character of 'totality' are already a consequence of the abandonment of Being. They press toward a guarantee of the stability of a constant form of using things up. Man, who no longer conceals his character of being the most important raw material, is also drawn into this process. Man is the 'most important raw material' because he remains the subject of all consumption. He does this in such a way that he lets his will be unconditionally equated with this process, and thus at the same time become the 'object' of the abandonment of Being. The world wars are the antecedent form of the removal of the difference between war and peace.
