This study critically reacts to the article “Etický význam lidství” (“The Ethical Significance of Humanity”) by Kamila Pacovská (Filosofický časopis, 62, 2014, No. 6, s. 863–875), and it discusses some relevant facts about the extrapolations of “human prejudice” to the domain of animal ethics that remain unnoticed in that article. It is shown that any attempt to found a responsible relation to animals on the basis of anthropomorphising criteria of “species” will be problematic, for the relevant concepts of “fairness” and “respect” will be applied with absurd consequences. An indiscriminate prohibition on killing all animals without distinction, although it may not be easy to justify philosophically, has the advantage of avoiding those absurd consequences.
