RT Article T1 On justifying arguments of species membership JF Bioethics VO 34 IS 2 SP 159 OP 165 A1 Rothhaar, Markus 1968- LA English PB Wiley-Blackwell YR 2020 UL https://www.ixtheo.de/Record/1727465865 AB In the debate about the moral status of human beings at the margins of life, arguments of species membership are often considered to be the least plausible ones. Against this backdrop, this article explores two possible ways to formulate feasible arguments of species membership. The first is an (in the broadest sense of the word) Aristotelian or neo-Aristotelian argument; the second is an argument from the intrinsic logic of human rights, which Robert Spaemann refers toas a ‘transcendental-pragmatic’ argument. On these grounds, the article proposes a philosophical justification for an at least moderate speciesism.
