Description
The concept of ENS - understood as “that which is” - belongs to the most fundamental and, at the same time, the most problematic categories of philosophy. It is unavoidable: no thinking, speaking, or denying is possible without already presupposing that “something is”. At the same time, ENS resists every attempt at final definition. Any definition turns it into yet another being, thereby losing sight of the fact that ENS is a condition of possibility for beings, not one of them. This dual character - necessity and indeterminacy - makes ENS a limit concept. Throughout the history of philosophy, various strategies have been developed to address this tension. Classical metaphysics treated ENS as the starting point of ontology; modern philosophy shifted it toward the conditions of knowledge; twentieth-century thought reframed it in terms of sense, language, and the disclosure of being. Despite these transformations, one feature remains constant: ENS cannot be closed without cost. Every attempt to absolutize it results in reduction - ontological, epistemological, or ideological.
