This text examines the fundamental concept of the uniqueness of every "true being." The author posits that every entity is ultimately non-interchangeable, despite the prevailing tendency in European philosophy and science to focus on similarities that allow for categorization and substitution. This dominant approach organizes beings into groups based on their commonalities, systematically neglecting the unique and unrepeatable qualities of the individual. The document highlights that our capacity to distinguish individual differences is often a result of long-term coexistence and a genuine interest in the specific nature of other beings. While such insights are frequently dismissed by scientific disciplines as subjective biases or anthropomorphic illusions, the author suggests that uniqueness might extend even to the subatomic level, where it remains hidden by statistical methods. Ultimately, the text warns against over-generalization and challenges the proactive exclusion of individual differences, urging a more attentive consideration of the inherent singularity of all existents.
