This text critically examines the issue of reductionism, rooted in ancient Greek philosophy. The author points out a fundamental error: the assumption that complex realities can be fully explained as mere assemblies of simpler elements. By comparing the ancient concept of atoms with modern physics, the text argues that despite our discovery of internal structures in subatomic particles, a reductionist tendency still persists in viewing higher contexts as external to their components. The central argument posits that individuals must possess an inherent capacity to respond to and integrate into higher, more complex contexts. Therefore, the world cannot be explained through physics alone, as if life, human consciousness, and history were mere side effects. Instead, higher levels of reality are fundamental aspects that require entities to have a cognitive relationship with the structures that enable their existence. The text advocates for a holistic ontological approach that transcends simple physicalist explanations.
