This paper explores the concept of meontology as a philosophical discipline that both transcends and integrates traditional Aristotelian ontology. The primary objective is to demonstrate that the establishment of meontology can be viewed as an attempt at a modern reconstitution of Aristotle's Physics. Unlike static ontology, meontology focuses on the dynamic aspects of reality, specifically on that which is manifold and subject to constant change. The author argues that this perspective allows for a better understanding of being in its processual and plural nature, thereby rehabilitating the Aristotelian conception of nature (physis) as a sphere of movement and becoming. The text examines the relationship between non-being and being within the context of ontological difference and seeks to define meontology as a science of multiplicity that complements classical metaphysical reflections. This reconstitution represents a return to questions of motion and change as fundamental characteristics of reality, which were often sidelined in later metaphysical traditions in favor of static substance. The work thus contributes to the discussion on the possibilities of contemporary ontology and its capacity to reflect the dynamic nature of the world.
