This reflection critically examines the relationship between motion and being, starting from the Aristotelian concept of motion as the actualization of potential. The author reflects on Rádl's interpretation, which paradoxically suggests that a moving subject appears inert or external to its own motion. However, this approach is challenged; motion is not merely an external attribute but an essential part of existence. The text argues that nothing in motion can remain truly indifferent to it. If a certain substrate appears unaffected by motion, it is only because this substrate is itself another type of motion that concerns it essentially. The paper emphasizes the need to distinguish between different forms of motion while simultaneously perceiving their inseparable connection. Motion is thus not something that happens to something static but is a process that defines the very essence of being. The goal is to overcome the dualism of the subject and its change in favor of a dynamic understanding of reality.
