The text explores the nature of concrete reality, defining it as a 'true event.' Etymologically derived from the Latin verb concrescere (to grow together), the concept emphasizes the processual and developmental character of existence. Reality is not viewed as a static object but as a dynamic occurrence through which a subject actively establishes and maintains its own integrity and boundaries. Each event integrates multiple dimensions of reality, specifically the triad of current presence, past, and future. Furthermore, the realization of an event involves incorporating other, lower-level events or their remnants into its own progression. The resulting structure is a complex synthesis of elements from various origins, integrated with varying degrees of intensity and success. When an event concludes, it leaves behind relics that may persist beyond its duration. The text offers an ontological perspective on reality as a dynamic system of interconnected events that continuously emerge, integrate diverse components, and eventually dissolve, leaving traces for future processes.
