This philosophical text examines the 'performance of being,' asserting that the existence of any genuine entity cannot be grounded in or maintained by mere inertia. Instead, inertia provides the material that a subject-event must actively utilize to perform its being. Crucially, inertias are not self-sustaining; they tend toward decay and aging, requiring active maintenance. The text rejects the notion of being as 'dead material' or passive building blocks. Instead, it posits a hierarchical structure of events where each relative whole—whether a molecule, a cell, or an organism—must actively constitute and preserve its existence. Lower-level entities (sub-wholes) within these structures also perform their own 'sub-being,' yet they do so in functional alignment with the overarching whole. Ultimately, being is characterized as a continuous, active effort of integration and self-renewal across various levels of ontological complexity.
