This text presents a philosophical analysis of the concept of inertia in relation to real existence. The author argues that inertia is not a characteristic of actual being but applies only to two specific categories of non-existential phenomena. The first category consists of intentional objects, such as geometric shapes and mental models, which are inert due to the nature of their conceptual construction and the way they are intended. The second category comprises virtual realities and events that are isolated from the real world, although they retain a certain residual reactivity. It is this minimal capacity for reaction that distinguishes virtual events from purely abstract concepts. Although the fragment remains unfinished, it offers significant ontological insights into the boundaries between human intention, virtual space, and actual reality. The text illuminates how we understand passivity within the context of constructed systems versus lived reality, which is reactive by definition and integrated into the world's events.
