The historical phenomenological and ideological oscillations, characterized as a retreat from the senses into the abstract and ideal and then back again, is not just a reaction to a corrupting external world, but an ever-encroaching necessity. It is the equivalent of matter and energy rushing into a vacuum.
Our global dominance is predicated on cognition, and so material and environmental failures tend to encourage the proportional buildup of abstract and ideological structures to account for those failings and formulate responses.
The problem with this is that once stabilization is achieved, all of that energy wants to keep moving, and so the idea and the abstraction becomes the deity, and then the material world burns. And a new idea must be formulated, as escape vessel.
Like whirling bolas traveling through the air, angling downward.
