This text explores the problematic nature of human zoological classification, drawing a parallel with taxonomic disputes in the world of cactus collecting. The author observes that while botanical naming controversies are often seen as intellectual challenges for enthusiasts, the classification of humans as primates frequently triggers defensive or angry responses. The essay reflects on the historical resistance to Darwinian evolution and popular works like "The Naked Ape." It argues that although the shared ancestry with primates is scientifically accepted, a purely zoological categorization fails to capture the essence of what makes humans unique. Humans have emancipated themselves from the animal kingdom to inhabit a distinct "human world" that is not merely an extension of nature. The author suggests that those who refuse to acknowledge this qualitative difference and insist on a strictly biological reduction of humanity are often viewed as narrow-minded or ideologically biased, as they ignore the unique sphere of human existence and culture.
