This text explores the philosophical and methodological foundations of quantification, focusing on its inherent limitations. The central argument is that the act of counting is not a mere recording of objective reality but requires a prior ontological decision regarding the nature of the observed entities. In order to quantify specific objects, we must first define them or decide how they are to be categorized. The author emphasizes that no two things in existence are ever perfectly identical. Therefore, quantification is only possible through a process of abstraction, during which we intentionally overlook the unique characteristics of individual elements and treat them as if they were uniform. This reductive process is essential for generating numerical expressions, but it also implies that every instance of measurement or counting necessarily ignores the concrete diversity of the world. The paper highlights that quantification is not a neutral operation but an active process of simplification that allows us to grasp reality through mathematical models at the cost of losing specific details.
