 Neo-Aristotelians claim that to describe an organism, whether a plant or a non-human or human animal, as flourishing is to measure it against a standard that is specific to the species to which it belongs. To do so is to evaluate it as a more or less good “specimen of its species (or sub-species)” (Hursthouse 1999: 198). The key move is then to claim that moral evaluation is, “quite seriously” (Foot 2001: 16), evaluation of the same sort: just as a non-defective animal or plant exemplifies flourishing within the relevant species’ life form, someone who is morally good is someone who exemplifies human flourishing, i.e., the fully developed form of the species. This metaethical claim has provoked the worry as to whether such attributions to other organisms are really anything more than classifications, or at most evaluations of “stretched and deflated” kinds that are missing the key feature of authority that we require for genuine normativity (Lenman 2005: 46ff.).
