Abstract

The predicate “natural” is often used in a normative fashion, especially in Bioethics. But that something is natural does not alone suffice to explain its value. In this essay, I want to fulfil mainly two tasks: Firstly, to differentiate between several usages of the concept of naturalness and scrutinize whether they may serve a function in ethics; secondly, to argue for the (eudaimonistic, not moral) value of naturalness in certain respects. The value of the natural lies firstly in its significance for human wellbeing: specific natural functions form necessary elements and conditions of the ability to lead a good life. Secondly, the very feature of the natural, its being purposeless, which implies that we cannot read our aims out of nature, serves as the basis of its eudaimonistic value.
