This study addresses the philosophical investigation of the relationship between the whole and its parts, a theme that has permeated human thought since its inception. The author analyzes two fundamental perspectives that emerge throughout the history of philosophy. The first approach emphasizes the dynamics of the whole, pointing out that the resulting entity can exhibit different characteristics even when composed of identical elements. Conversely, the second perspective focuses on the ontological stability of the whole, arguing that the identity of the whole can remain preserved even in situations where its individual parts undergo gradual replacement or change. The text reflects on these opposing approaches and suggests how these concepts influence our understanding of the structure of reality and the identity of objects over time. The analysis stems from historical context and aims for a deeper understanding of the dialectic between composition and unity, which forms a fundamental pillar of metaphysical reflections on the nature of being. The objective is to clarify how these distinct viewpoints complement or exclude each other within systematic philosophy.
