The concept of autonomy as self-sovereignty is developed in this essay through an examination of the thought of American transcendentalist philosophers Emerson and Thoreau. It is conceived as the quality of living in accordance with one’s inner nature or genius. This conception is grounded in a transcendentalist moral anthropology that values independence, self-reliance, spirituality, and the capacity to find beauty in the world. Though still exerting considerable popular and academic influence, both the concept of autonomy as self-sovereignty and the underlying (...) anthropology diverge in important ways from counterparts that are prominent in contemporary bioethics. Autonomy as self-sovereignty calls into question the manifold ways that patients (and citizens) are brought to heel by institutional (and political) values they do not themselves affirm. It also emphasizes the inevitable deep plurality of moral visions of health and appropriate healthcare, rejecting tendencies (strong in mainstream bioethics) to regard “health” as a univocal concept or healthcare as a basic need, to attempt to conform “reasonable” clinical decision-making to a single model, and to appoint government as a guarantor of access to healthcare or a regulator of healthcare standards. Autonomy as self-sovereignty, like its competitors, can justify itself only in question-begging terms. Still, bioethics might do well to recognize it within the mix of moral visions. (shrink)
