This study explores the field of meontology, the philosophical investigation of non-being, and asserts the necessity of addressing its core problems. The author illustrates the relevance of meontological questions within everyday life, while highlighting their critical importance in scientific disciplines such as astronomy, astrophysics, cosmology, and subnuclear physics. The paper further emphasizes the role of meontology in the arts, specifically regarding artistic creation and the nature of artifacts. Once a conceptual foundation is established, the text shifts toward practical applications, examining the problems of norms, evaluative criteria, and the ontological condition of "what ought to be." These themes are subsequently applied to the fields of ethics and ethology. The primary objective is to demonstrate that understanding non-being is essential for a comprehensive interpretation of both physical reality and human conduct. By connecting metaphysical foundations with scientific inquiry and cultural expression, the work shows that meontology provides a vital framework for analyzing morality and social norms.
