In this context, it sounds as though "qua" is being used to mean "considered as." So, for example, qua sentient being (i.e., considered as a sentient being) you have particular rights, while qua adult citizen (i.e., considered as an adult citizen) you have those rights plus additional rights, such as the right to vote. I see no contradiction here.
Hi, While reading aristotle and aquinas on part whole relationship i often read the phrase "something qua itself and qua something else" as in man qua headed or qua an animal, what do they mean by that ? and how can something be qua itself and at the same time be as something else ? Isnt that a contardiction ? Thanks in advance
