This text explores the significance and function of precise concepts within the context of linguistic communication and ontological identity. The author distinguishes between two primary functions of conceptualization: ensuring identity of meaning for mutual understanding and identifying the identity of reality itself amidst constant change. A central problem is how to define the unity of a being that evolves over time and reacts to external circumstances. The text critically evaluates classical Greek conceptualization, which projects unchanging mental models onto changing phenomena as guarantors of permanence. In contrast, the author argues for the necessity of a "new" conceptualization. This new form should move away from seeking unchanging substances as the basis for concrete event-based unity, without lapsing into nominalism that reduces such unity to a mere name or "flatus vocis." The objective is to find a way to conceptualize event-based unity as a process that maintains its identity through transformation and development, rather than being reduced to a static object or a mere sound.
