This text explores the relationship between humanity and nature (physis), drawing on the ancient Greek distinction between what occurs naturally and what is created or co-created by human intervention. The author critically reflects on the modern scientific approach, which strictly separates human traces from natural observations to ensure objectivity. The core of the inquiry questions the validity of this distinction: why are the constructions of animals, such as nests or anthills, considered natural, while human activities are excluded from this category? The reflection challenges anthropocentric dualism and raises questions about the ontological status of human beings within the universe. If humans themselves are "by nature," just like ants or birds, is it legitimate to view their actions as inherently separate from the natural world? This brief philosophical excursion encourages a reassessment of the boundaries between culture and nature, urging a deeper consideration of what it truly means to be part of the natural world in both scientific and general thought. The document serves as a catalyst for rethinking our fundamental categorizations of the environment.
